have called complemental males; we have, as Mr. Wallace has lately shown, the females of certain Lepidoptera existing under three distinct forms; but in none of these cases is there any reason to suppose suspect that there is more than one female or one male sexual element. With certain insects, as low as with ants in which there exist besides males females, two or three castes of workers, we have a slightly nearer approach to our case, for the workers are so far sexually affected, as to have been

certain insects, as with Ants, in which there exist, besides males and females, two or three castes of workers, we have a slightly nearer approach to our case, for the workers are so far sexually affected as to have been rendered sterile. With plants, at least with phanerogamic plants, we have not that wonderful series of successive developmental forms so common with animals; nor could this be expected, as plants are fixed to one spot from their birth, and must be adapted throughout life to the same

expression, is offered as a full and logical solution of the whole difficulty. We will give but two instances, out of a host. The constant re-production, in every community of bees and ants, of working neuters, presenting a fixed structure different from their parents, is a mystery which is fatal to his hypothesis; for this peremptorily demands that the acquisition and perpetuation of any given form, shall be the effect of direct inheritance. His hypothesis, therefore, will not apply to those forms the

to my imagination it is far more satisfactory to look at such instincts as the young cuckoo ejecting its foster-brothers, ants making slaves, the larv of ichneumonid feeding within the live bodies of caterpillars, not as specially endowed or created instincts, but as small consequences of one general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.

yielding, as was first observed by Huber, their sweet excretion to ants: that they do so voluntarily, the following facts show. I removed all the ants from a group of about a dozen aphides on a dock-plant, and prevented their attendance during several hours. After this interval, I felt sure that the aphides would want to excrete. I watched them for some time through a lens, but not one excreted; I then tickled and stroked them with a hair in the same manner, as well as I could, as the ants do

Smith. Although so small a species, it is very courageous, and I have seen it ferociously attack other ants. In one instance I found to my surprise an independent community of F. flava under a stone beneath a nest of the slave-making F. sanguinea; and when I had accidentally disturbed both nests, the little ants attacked their big neighbours with surprising courage. Now I was curious to ascertain whether F. sanguinea could distinguish the pup of F. fusca, which they habitually make into slaves

The latter ruthlessly killed their small opponents, and carried their dead bodies as food to their nest, twenty-nine yards distant; but they were prevented from getting any pup to rear as slaves. I then dug up a small parcel of the pup of F. fusca from another nest, and put them down on a bare spot near the place of combat; they were eagerly seized and carried off by the tyrants, who perhaps

By what steps the instinct of F. sanguinea originated I will not pretend to conjecture. But as ants, which are not slave-makers, will, as I have seen, carry off pup of other species, if scattered near their nests, it is possible that such pup originally stored as food might become developed; and the foreign

tendency to produce sterile members having the same modification. And I believe that this process has been repeated, until that prodigious amount of difference between the fertile and sterile females of the same species has been produced, which we see in so many social insects. But we have not as yet touched on the climax of the difficulty; namely, the fact that the neuters of several ants differ, not only from the fertile females and males, but from each other, sometimes to an almost incredible

, that if the smaller workers had been the most useful to the community, and those males and females had been continually selected, which produced more and more of the smaller workers, until all the workers had come to be in this condition; we should then have had a species of ant with neuters very nearly in the same condition with those of Myrmica. For the workers of Myrmica have not even rudiments of ocelli, though the male and female ants of this genus have well-developed ocelli. I may give

can see how useful their production may have been to a social community of ants, on the same principle that the division of labour is useful to civilised man. Ants, however, work by inherited instincts and by inherited organs or tools, whilst man works by acquired knowledge and manufactured instruments. But I must confess, that, with all my faith in natural selection, I should never have anticipated that this principle could have been efficient in so high a degree, had not the case of these

trimorphic animals and plants which have been studied are not now connected together by intermediate links, it is probable that this will be found to occur in other cases; for Mr. Wallace observed a certain butterfly which presented in the same island a great range of varieties connected by intermediate links, and the extreme links of the chain closely resembled the two forms of an allied dimorphic species inhabiting another part of the Malay archipelago.

three years old with wonderfully little practice, had played a tune with no practice at all, he might truly be said to have done so instinctively. But it would be the most serious error to suppose that the greater number of instincts have been acquired by habit in one generation, and then transmitted by inheritance to succeeding generations. It can be clearly shown that the most wonderful instincts with which we are acquainted, namely, those of the hive-bee and of many ants, could not possibly have

It is now commonly admitted that the more immediate and final cause of the most remarkable of the instincts of the cuckoo is, that she lays her eggs, not daily, but at intervals of two or three days; so that, if she were to
