believe that this is generally true, and that, if no great number of hens be kept, the eggs of each can almost always be recognised. The eggs of differently sized breeds naturally differ much in size; but, apparently, not always in strict relation to the size of the hen: thus the Malay is a larger bird than the Spanish, but generally she produces not such large eggs; white Bantams are said to lay smaller eggs than other Bantams;36 white Cochins, on the other hand, as I hear from Mr. Tegetmeier

It may naturally be asked whether these remarkable modifications in the form of the brain affect the intellect of Polish fowls; some writers have stated that they are extremely stupid, but Bechstein and Mr. Tegetmeier have shown that this is by no means generally the case. Nevertheless Bechstein69 states that he had a Polish hen which was crazy, and anxiously wandered about all day long. A hen in my possession was solitary in her habits, and was often so absorbed in reverie that she could be

head of an owl or barb, its most striking peculiarity being the extraordinary length of the tail and wing-feathers, the latter crossing beyond the tail, and giving to the bird the appearance of a gigantic swift (Cypselus), or long-winged hawk. Mr. Tegetmeier informs me that this bird weighed only 10 ounces, but in length was 15 1/2 inches from tip of beak to end of tail, and 32 1/2 inches from tip to tip of wing; now the wild rock-pigeon weighs 14 1/2 ounces, and measures from tip of beak to end

dark spots on the head and rump, with occasionally a longitudinal stripe (Dixon) on the back of the neck. I have seen only one chicken of the silver-spangled Hamburgh, and this was obscurely striped along the back. Gold-spangled Polish chickens (Tegetmeier) are of a warm russet brown; and silver-spangled Polish chickens are grey, sometimes (Dixon) with dashes of ochre on the head, wings, and breast. Cuckoo and blue-dun fowls (Dixon) are grey in the down. The chickens of Sebright Bantams (Dixon

flight-feathers. On the other hand, in carriers and runts, which have large bodies and long wings, eleven primary feathers have occasionally been observed. Mr. Tegetmeier has informed me of a curious and in explicable case of correlation, namely, that young pigeons of all breeds, which when mature become white, yellow, silver, (i. e. extremely pale blue), or dun-coloured, are born almost naked; whereas other coloured pigeons are born well clothed with down.

hardly at all pencilled, this kind of plumage being confined to the female. Another case of analogous variation is the occurrence of spangled sub-breeds of Hamburgh, Polish, Malay, and Bantam fowls. Spangled feathers have a dark mark, properly crescent-shaped, on their tips; whilst pencilled feathers have several transverse bars. The spangling cannot be due to reversion to G. bankiva; nor does it often follow, as I hear from Mr. Tegetmeier, from crossing distinct breeds; but it is a case of

In some Indian Game-cocks, received by Mr. Brent from Germany, there are, as he informs me, three, four, or even five spurs on each leg. Some Dorkings also have two spurs on each leg;53 and in birds of this breed the spur is often placed almost on the outside of the leg. Double spurs are mentioned in the ancient Chinese Encyclopædia. Their occurrence may be considered as a case of analogous variation

It may naturally be asked whether these remarkable modifications in the form of the brain affect the intellect of Polish fowls; some writers have stated that they are extremely stupid, but Bechstein and Mr. Tegetmeier have shown that this is by no means generally the case. Nevertheless Bechstein69 states that he had a Polish hen which was crazy, and anxiously wandered about all

of spangled sub-breeds of Hamburgh, Polish, Malay, and Bantam fowls. Spangled feathers have a dark mark, properly crescent-shaped, on their tips; whilst pencilled feathers have several transverse bars. The spangling cannot be due to reversion to G. bankiva; nor does it often follow, as I hear from Mr. Tegetmeier, from crossing distinct breeds; but it is a case of analogous variation, for many gallinaceous birds have spangled feathers, for instance, the common pheasant. Hence spangled breeds

neck, loins, and upper wing-coverts. Here again we have a more decided, though partial, reversion to the colours of G. bankiva. This second cock was in fact coloured like an inferior pile Game cock; now this sub-breed can be produced, as I am informed by Mr. Tegetmeier, by crossing a black-breasted red Game cock with a white Game hen, and the pile sub-breed thus produced can afterwards be truly propagated. So that we have the curious fact of the glossy-black Spanish cock and the black-breasted

domestication of the pigeon, and therefore would be likely still to vary; these variations moreover have been recently, and are still being accumulated by man's selection; therefore they have not as yet become firmly fixed. Fifthly.—All the domestic races pair readily together, and, what is equally important, their mongrel offspring are perfectly fertile. To ascertain this fact I made many experiments, which are given in the note below; and recently Mr. Tegetmeier has made similar experiments

be specifically distinct, and were named G. œneus. Mr. Blyth and others believe that the G. Temminckii18 (of which the history is not known) is a similar hybrid. Sir J. Brooke sent me some skins of domestic fowls from Borneo, and across the tail of one of these, as Mr. Tegetmeier observed, there were transverse blue bands like those which he had seen on the tail-feathers of hybrids from G. varius, reared in the Zoological Gardens. This fact apparently indicates that some of the fowls of Borneo

chickens are almost invariably black. According to Mr. Brent, black and white Cochins occasionally produce chickens of a slaty-blue tint; and this same tint appears, as Mr. Tegetmeier tells me, from crossing white Cochins with black Spanish fowls, or white Dorkings with black Minorcas.59 A good observer60 states that a first-rate silver-spangled Hamburgh hen gradually lost the most characteristic qualities of the breed, for the black lacing to her feathers disappeared, and her legs changed

another way; for Mr. Tegetmeier informs me that if chickens lately hatched be selected with a large bony protuberance, when adult they will have a large crest. There can be no doubt that in former times the breeder of Polish fowls attended solely to the crest, and not to the skull; nevertheless, by increasing the crest, in which he has wonderfully succeeded, he has unintentionally made the skull protuberant to an astonishing degree; and through correlation of growth, he has at the same time

The author, who remarks on the two negatives ('Journ. of Hort.,' 1862, p. 325), states that two broods were raised from a Spanish cock and Silver-pencilled Hamburgh hen, neither of which are incubators, and no less than seven out of eight hens in these two

and Frizzled, and shorter in the Silk and Bantam breeds, than in the wild G. bankiva; but in the latter, as we have seen, the tarsi vary in length. The tarsi are often feathered. The feet in many breeds are furnished with additional toes. Golden-spangled Polish fowls are said64 to have the skin between their toes much developed; Mr. Tegetmeier observed this in one bird, but it was not so in one which I examined. In Cochins the middle toe is said65 to be nearly double the length of the lateral toes

this colour appeared; and one magnificent bird, the offspring of a black Spanish cock and white Silk hen, was coloured almost exactly like the wild Gallus bankiva. All who know anything of the breeding of poultry will admit that tens of thousands of pure Spanish and of pure white Silk fowls might have been reared without the appearance of a red feather. The fact, given on the authority of Mr. Tegetmeier, of the frequent appearance, in mongrel fowls, of pencilled or transversely-barred feathers

; and this was likewise the case with a hybrid which I once saw between a jackal and terrier. I cannot doubt, from the observations of Colin and others, that the ass is prepotent over the horse; the prepotency in this instance running more strongly through the male than through the female ass; so that the mule resembles the ass more closely than does the hinny.16 The 13 'Physiology of Breeding,' p. 22; Mr. Hewitt, in 'The Poultry Book,' by Tegetmeier, 1866, p. 224. 14 Boitard and Corbi , 'Les

worker being almost always attacked when trying to enter another hive. But Mr. Tegetmeier has shown38 that this instinct does not apply to drones, which are permitted to enter any hive; so that there is no priori improbability of a queen receiving a foreign drone. The fact of the union invariably and necessarily taking place on the wing, during the queen's nuptial flight, seems to be a special provision against continued interbreeding. However this may be, experience has shown, since the

variability to work upon. We see in this country considerable diversity in size, some in the proportions of the body, and extreme variability in colouring. I have only lately attended to this subject, but have already heard of some singular cases of variation; one of a cat born in the West Indies toothless, and remaining so all its life.

one primitive form. The white Silk fowl with black skin and bones degenerates, as has been observed by Mr. Hewitt and Mr. R. Orton, in our climate; that is, it reverts to the ordinary colour of the common fowl in its skin and bones, due care having been taken to prevent any cross.

sometimes even possesses the eminently masculine character of spurs. Many cases are on record of hens bring furnished with spurs; and in Germany, according to Bechstein,56 the spurs in the Silk-hen are sometimes very long. He mentions also another breed similarly characterized, in which the hens are excellent layers, 54 Dixon,Ornamental and Domestic Poultry,p. 320. 55 Mr. Tegetmeier informs me that Game hens have been found so combative, that it is now generally the practice to exhibit each hen in a

aborted. A large crest of feathers, as Mr. Tegetmeier has remarked, seems always accompanied by a great diminution or almost entire absence of the comb. A large beard is similarly accompanied by diminished or absent wattles. These latter cases apparently come under the law of compensation or balancement of growth. A large beard beneath the lower jaw and a large top-knot on the skull often go together. The comb when of any peculiar shape, as with Horned, Spanish, and Hamburgh fowls, affects in a

Turning now to domesticated and confined birds, I will commence by giving what little I have learnt respecting the courtship of fowls. I have received long letters on this subject from Messrs.

It will be admitted by every one that these gentlemen, so well known from their published works, are careful and experienced observers. They do not believe that the

The males of some lizards, when fighting together during their courtship, expand their throat pouches or frills, and erect their dorsal crests.16 But Dr. Günther does not believe that they can erect their separate spines or scales.

With respect to the formation of wax, it is known that bees are often hard pressed to get sufficient nectar, and I am informed by Mr. Tegetmeier that it has been experimentally proved that from twelve to fifteen pounds of dry sugar are consumed by a hive of bees for the secretion of a pound of wax; so that a prodigious quantity of fluid nectar must be collected and consumed by the bees in a hive for the secretion of the wax necessary for the construction of their combs

An analogous case has actually occurred, for there are breeds of the pigeon in Belgium4 in which the males alone are marked with black stri So again Mr. Tegetmeier has recently shewn5 that dragons not rarely produce silver-coloured birds, which are almost always hens; and he himself has bred ten such females. It is on the other hand a very unusual event when a silver male is produced; so that nothing would be easier, if

Mr. Tegetmeier, at my request, stained some of his birds with magenta, but they were not much noticed by the others. Female pigeons occasionally feel a strong antipathy towards certain males, without any assignable cause. Thus MM. Boitard and Corbi , whose experience extended over forty-five years, state: Quand une

Mr. Tegetmeier has known a Brahma to weigh 17 pounds; a fine Malay cock 10 pounds; whilst a first-rate Sebright Bantam weighs hardly more than 1 pound. During the last 20 years the size of some of our breeds has been largely increased by methodical selection, whilst that of other breeds has been much diminished. We have already seen

crossing beyond the tail, and giving to the bird the appearance of a gigantic swift (Cypselus), or long-winged hawk. Mr. Tegetmeier informs me that this bird weighed only 10 ounces, but in length was 15½ inches from tip to beak to end of tail, and 32½ inches from tip to tip of wing; now the wild rock-pigeon weighs 14½ ounces, and measures from tip to beak to end of tail 15 inches, and from tip to tip of wing only 26¾ inches.

with the mottling partially and obscurely arranged in transverse lines. But the tendency to pencilling is probably much strengthened by the law of analogous variation, for the hens of some other species of Gallus are more plainly pencilled, and the hens of many gallinaceous birds belonging to other genera, as the partridge, have pencilled feathers. Mr. Tegetmeier has also remarked to me that, although with domestic pigeons we have so great a diversity of colouring, we never see either

The same kind of double selection has come into play with the carrier pigeon, for during their training the inferior birds fail to return home and are lost, so

I have seen only one chicken of the silver-spangled Hamburgh, and this was obscurely striped along the back. Gold-spangled Polish chickens (Tegetmeier) are of a warm russet brown; and silver

Mr. Tegetmeier has shown me the skull of a female cat with its canines so much developed that they protruded uncovered beyond the lips; the tooth with the fang being .95, and the part projecting from the gum .6 of an inch in length. I have heard of several families of six-toed cats, in one of which the peculiarity had been transmitted for at least three generations. The tail varies greatly in length; I have seen a cat which always carried its tail

whereas pigeons of other colours are born well-clothed with down. Mr. Esquilant, however, has observed that young dun Carriers are not so bare as young dun Barbs and Tumblers. Mr. Tegetmeier has seen two young birds in the same nest, produced from differently coloured parents, which differed greatly in the degree to which they were at first clothed with down. I have observed another case of correlation which at first sight appears quite inexplicable, but on which, as we shall see in a future

The facts hitherto given refer to the occasional appearance in pure races of blue birds with black wing-bars, and likewise blue Barb; and Mr. H. Weir, as I am informed by Mr. Tegetmeier, once bred a silver (which means very pale blue) Barb from two yellow birds. 25 Mr. Blyth informs me that all the domestic races in India have the croup blue; but this is not invariable, for I possess a

resembling the wild G. bankiva. Mr. Tegetmeier has been so kind as to repeat, at my request, the cross between a Spanish cock and Silk hen, and he obtained similar results; for he thus raised, besides a black hen, seven cocks, all of which were dark-bodied with more or less orange-red hackles. In the ensuing year he paired the black hen with one of her brothers, and raised three young cocks, all coloured like their father, and a black hen mottled with white. The hens from the six above-described

Osteological Differences.—I have examined twenty-seven skeletons and fifty-three skulls of various breeds, including three of G. bankiva: nearly half of these skulls I owe to the kindness of Mr. Tegetmeier, and three of the skeletons to Mr. Eyton. The Skull differs greatly in size in different breeds, being nearly twice as long in the largest Cochins, but not nearly twice as broad, as in Bantams. The bones at the

its colour and that of the legs are both slightly variable.28 This latter fact deserves attention, because the colour of the legs and beak is highly serviceable in discriminating the several closely allied wild forms.29 At our Shows two breeds are exhibited; viz., the Embden and Toulouse; but they differ in nothing except colour.30 Recently a smaller and singular variety has been imported from Sebastopol,31 with the scapular feathers (as I hear from Mr. Tegetmeier, who sent me specimens

These Runts are apt to tremble like Fantails. They are bad flyers. A few years ago Mr. Gulliver11 exhibited a Runt which weighed 1 lb. 14 oz.; and, as I am informed by Mr. Tegetmeier, two Runts from the south of France were lately exhibited at the Crystal Palace, each of which weighed 2 lbs. 2½ oz. A very fine rock-pigeon from the Shetland Islands weighed only 14½ oz. Sub-race IV. Tronfo of Aldrovandi (Leghorn Runt?).—In Aldrovandi's work published in 1600 there is a coarse woodcut of a great

femur considerably longer in the Spanish and Frizzled, and shorter in the Silk and Bantam breeds, than in the wild G. bankiva; but in the latter, as we have seen, the tarsi vary in length. The tarsi are often feathered. The feet in many breeds are furnished with additional toes. Golden-spangled Polish fowls are said64 to have the skin between their toes much developed: Mr. Tegetmeier observed this in one bird, but it was not so in one which I examined. Prof. Hoffmann has sent me a sketch of

magnificent bird, the offspring of a black Spanish cock and white Silk hen, was coloured almost exactly like the wild Gallus bankiva. All who know anything of the breeding of poultry will admit that tens of thousands of pure Spanish and of pure white Silk fowls might have been reared without the appearance of a red feather. The fact, given on the authority of Mr. Tegetmeier, of the frequent appearance, in mongrel fowls, of pencilled or transversely-barred feathers, like those common to many

We thus see that there is almost complete unanimity with poultry-breeders that, when fowls are kept at the same place, evil quickly follows from interbreeding carried on to an extent which would be disregarded in the case of most quadrupeds. Moreover, it is a generally received opinion that cross-bred chickens are the hardiest and most easily reared.37 Mr. Tegetmeier, who has carefully attended to poultry of all breeds, says38 that Dorking hens, allowed to run with Houdan or Crevecœur cocks

experiment. Following the example of Mr. Tegetmeier, I separated two combs, and put between them a long, thick, rectangular strip of wax: the bees instantly began to excavate minute circular pits in it; and as they deepened these little pits, they made them wider and wider until they were converted into shallow basins, appearing to the eye perfectly true or parts of a sphere, and of about the diameter of a cell. It was most interesting to observe that, wherever several bees had begun to excavate

It will be admitted by every one that these gentlemen, so well known from their published works, are careful and experienced observers. They do not believe that the females prefer certain males on account of the beauty of their plumage; but some allowance must be made for the artificial state under which these birds have long been kept.

how far selection has come into play in determining the result. Horses.—Mr. Tegetmeier has been so kind as to tabulate for me from the 'Racing Calendar' the births of race-horses during a period of twenty-one years, viz., from 1846 to 1867; 1849 being omitted, as no returns were that year published. The total births were 25,560,58 consisting of 12,763 males and 12,797 females, or in the proportion of 99.7 males to 100 females. As these numbers are tolerably large, and as they are drawn from all

94.7 to 100. In regard to domestic pigeons there is good evidence either that the males are produced in excess, or that they live longer; for these birds invariably pair, and single males, as Mr. Tegetmeier informs me, can always be purchased cheaper than females. Usually the two birds reared from the two eggs laid in the same nest are a male and a female; but Mr. Harrison Weir, who has been so large a breeder, says that he has often bred two cocks from the same nest, and seldom two hens

An undubbed bird, as Mr. Tegetmeier insists, is at a fearful disadvantage; the comb and gills offer an easy hold to his adversary's beak, and as a cock always strikes where he holds, when once he has seized his foe, 93 On the Cosmetornis, see Livingstone's 'Expedition to the Zambesi,' 1865, p. 66.

caractère de leur coloration venaient à surgir chez certains mâles, et que ces variations fussent dès le principe limitées dans leur transmission au sexe mâle, la production de la race cherchée deviendrait facile, car il suffirait simplement de choisir ces mâles et de les accoupler avec des femelles ordinaires. Un cas analogue s'est présenté, car il existe en Belgique[4] certaines races de pigeons chez lesquelles les mâles seuls portent des raies noires. M. Tegetmeier[5] a récemment démontré que

rapport de 94,7 à 100. Il est évident que, chez le pigeon domestique, les mâles sont produits en excès, ou qu'ils vivent plus longtemps ; car ces oiseaux s'accouplent, et M. Tegetmeier m'apprend que les mâles isolés coûtent toujours moins cher que les femelles. Ordinairement, les deux oiseaux provenant des deux œufs pondus dans le même nid consistent en un mâle et une femelle ; cependant M. Harrison Weir, qui a élevé beaucoup de pigeons, assure qu'il a souvent eu deux femelles ; en outre, la

males would simply have to be selected and matched with ordinary females: An analogous case has actually occurred, for there are breeds of the pigeon in Belgium4 in which the males alone are marked with black striæ. So again Mr. Tegetmeier has recently shewn5 that dragons not rarely produce silver-coloured birds, which are almost always hens; and he himself has bred ten such females. It is on the other hand a very unusual event when a silver male is produced; so that nothing would be easier, if

Registrar's Report for 1866. Dogs.—During a period of twelve years, from 1857 to 1868, the births of a large number of greyhounds, throughout England, were sent to the 'Field' newspaper; and I am again indebted to Mr. Tegetmeier for carefully tabulating the results. The recorded births were 6878, consisting of 3605 males and 3273 females, that is, in the proportion of 110.1 males to 100 females. The greatest fluctuations occurred in 1864, when the proportion was as 95.3 males, and in 1867, as

many weeks with a silver (i.e., very pale blue) male, and at last mated with him. Nevertheless, as a general rule, colour appears to have little influence on the pairing of pigeons. Mr. Tegetmeier, at my request, stained some of his birds with magenta, but they were not much noticed by the others. Female pigeons occasionally feel a strong antipathy towards certain males, without any assignable cause. Thus MM. Boitard and Corbié, whose experience extended over forty-five years, state: Quand une

instead of a double cylindrical wall of separate cells, there wax should have been saved. Thus we can see how natural selection would have worked towards the developing of an instinct to excavate cells near enough together to produce intersection; and once begun, there is no reason why this instinct should not have been perfected by the same agency, till we meet with its ideal perfection in the hive-bee. For as Mr. Darwin observes, With respect to the formation of wax, it is known that bees

My father was fond of quoting this passage, and always with a tone of fellow-feeling for the author, though, no doubt, he had forgotten his own wonderings as a child that every gentleman did not become an ornithologist.

from their being accustomed, when in danger, either to squat on the ground or to sit motionless on a branch, so as to escape detection. Though, with birds, anger may be the chief and commonest cause of the erection of the feathers, it is probable that young cuckoos when looked at in the nest, and a hen with her chickens when approached by a dog, feel at least some terror. Mr. Tegetmeier informs me that with game-cocks, the erection of the feathers on the head has long been recognized in the
