It examined the mark and more than once attempted to seize it. This observation has been repeated with birds and African butterflies by Mr. Guy Marshall and others, while large numbers of specimens have been collected with injuries to the wing at or near an eye-spot. Hence the conclusion that the usual value of these markings is to divert attention from the vital parts and give the insect extra chance of escape. Their disappearance from the dry season broods is interpreted as due to the

In the case of the Caroline Marshall archipelagos, which are situated nearer each other but extend in different directions, it seems probable that their subsidence has been independent; for the Mc'Askill islands, (*Dana. Corals Coral Islands p. 306) lie towards the eastern end of the Caroline [few words excised] are

reef, that part which I have sometimes called the 'flat,' and which is partly dry at low water, appears similar in every atoll. In the Marshall group in the N. Pacific, it may be inferred from Chamisso's description, that the reef, where islets have not been formed on it, slopes gently from the external margin to the shores of the lagoon: Flinders states that the Australian barrier has a similar inclination inwards, and I have no doubt it is of general occurrence, although, according to Ehrenberg

concerned, seems highly probable, when we observe that the three principal groups are directed in N.W. and S.E. lines, and that nearly all the land in the S. Pacific ranges in this same direction; namely, N. Western Australia, New Caledonia, the northern half of New Zealand, the New Hebrides, Saloman, Navigator, Society, Marquesas, and Austral archipelagoes: in the Northern Pacific, the Caroline atolls abut against the N.W. line of the Marshall atolls, much in the same manner as the E. and W. line

islets, united into great rings, rise above the stated level. The Gilbert group is very narrow, and 300 miles in length. In a prolonged line from this group, at the distance of 240 miles, is the Marshall archipelago, the figure of which is an irregular square, one end being broader than the other; its length is 520 miles, with an average width of 240: these two groups together are 1040 miles in length, and all their islets are low. Between the southern end of the Gilbert and the northern end of Low

these views, it may be asked how it comes 1 In the Origin, Ed. i. p. 41, vi. p. 46 the question is differently treated; it is pointed out that a large stock of individuals gives a better chance of available variations occurring. Darwin quotes from Marshall that sheep in small lots can never be improved. This comes from Marshall's Review of the Reports to the Board of Agriculture, 1808, p. 406. In this Essay the name Marshall occurs in the margin. Probably this refers to loc. cit. p. 200, where

45° into unfathomable depths, is exactly the same* with that of the sections of the atolls in the Low Archipelago given by Capt. Beechey. The nature, however, of the bottom seems to differ, for this officer† informs * The form of the bottom round the Marshall atolls in the Northern Pacific is probably similar: Kotzebue (First Voyage, vol. ii. p. 16.) says, We had at a small distance from the reef, forty fathoms depth, which increased a little further so much that we could find no bottom. † I must

absolutely similar to that described by Chamisso in the Marshall atolls. In the Society Archipelago, Ellis* states, that the reefs generally lie at the distance of from one to one and a half miles, and, occasionally, even at more than three miles, from the shore. The central mountains are generally bordered by a fringe of flat, and often marshy, alluvial land, from one to four miles in width. This fringe consists of coral-sand and detritus thrown up from the lagoon-channel, and of soil washed

of Mauritius where I found the coral growing at a somewhat greater depth than at Keeling atoll, the sea, owing apparently to its tranquil state, was likewise very clear. Within the lagoons of some of the Marshall atolls, where the water can be but little agitated, there are, according to Kotzebue, living beds of coral in 25 fathoms. From these facts, and considering the manner in which the beds of clean coral off Mauritius, Keeling Island, the Maldiva and Chagos atolls, graduated into a sandy

by a bed of mould, which, after an earthquake, disappeared, and was believed by the resident to have been washed by the rain through the broken masses of underlying rock: the island was thus rendered unproductive. Chamisso† states, that earthquakes are felt in the Marshall atolls, which are far from any high land, and likewise in the islands of the Caroline Archipelago. On one of the latter, namely Oulleay atoll, Admiral Lutké, as he had the kindness to inform me, observed several straight

movement. Mountain-chains, however, when already formed, although running in very different directions, it seems,† may be raised together by a widely-acting force: so, perhaps, mountain-chains may subside together. Hence, we cannot tell whether the Caroline and Marshall Archipelagoes, two groups of atolls running in different directions and meeting each other, have been formed by the subsidence of two areas, or of one large * Researches in Physical Geology, Transact.

, I know not; but we shall presently meet with it, under precisely the same form, on the outer edge of the 'barrier reefs' which encircle the Society Islands. There appears to be scarcely a feature in the structure of Keeling reef, which is not of common, if not of universal occurrence, in other atolls. Thus Chamisso describes‡ a layer of coarse conglomerate, outside the islets round the Marshall atolls, which appears on its upper surface uneven and eaten away. From drawings, with appended

partly submerged with barrier-reefs marking their former limits, such as New Caledonia, so our theory makes it probable that there should be other large islands wholly submerged; and these, we may now infer, would be surmounted, not by one enormous atoll, but by several large elongated ones, like the atolls in the Maldiva group; and these again, during long periods of subsidence, would sometimes become dissevered into smaller atolls. I may add, that both in the Marshall and Caroline Archipelagoes

MARSHALL GROUP.—We are well acquainted with this group from the excellent charts of the separate islands, made during the two voyages of Kotzebue: a reduced one of the whole group may be easily seen in Krusenstern's Atlas, and in Kotzebue's Second Voyage. The group consists (with the exception of two little islands which probably have had their lagoon filled up,) of a double row of 23 large and well-characterized atolls, from the examination of which Chamisso has given us his well-known account of
