[...]... the chief forms of which were easily to be obtained alive in some abundance The Crabs and Macrurous Crustacea, the Stomapoda, the Diastylidae, the Amphipoda and Isopoda, the Ostracoda and Daphnidae, the Copepoda and Parasita, the Cirripedes and Rhizocephala of our coast, representing the class of Crustacea with the deficiency only of the Phyllopoda and Xiphosura, furnished a long and varied, and at the... the often incredible difference in the development of the most nearly allied forms, these must be separately studied—usually family by family, and frequently genus by genus— nay, sometimes, as in the case of Peneus, even species by species; and because these investigations, in themselves troublesome and tedious, often depend for their success upon a lucky chance But although the satisfactory completion... supports for Darwin's theory Nor, so far as I am aware, have any of the NECESSARY consequences of Darwin's hypotheses been proved by any one else, to stand in clear and irreconcilable contradiction And yet, as the most profound students of the animal kingdom are amongst Darwin's opponents, it would seem that it ought to have been an easy matter for them to crush him long since beneath a mass of absurd and. .. intermediate forms between the species of the various strata of the earth Independently of the reasons which Darwin gives for the preservation of such intermediate forms being only exceptional, this last mentioned circumstance will not be regarded as of very great significance by any one who has traced the development of an animal upon larvae fished from the sea, and had to seek in vain for months, and even... fished from the sea, and had to seek in vain for months, and even years, for those transitional forms, which he nevertheless knew to be swarming around him in thousands A few examples may show how contradictions might come forth as necessary results of the Darwinian hypotheses It seems to be a necessity for all crabs which remain for a long time out of the water (but why is of no consequence to us here),... are seen projecting between the legs.) A second example.—We are already acquainted with four species of Melita (M valida, setipes, anisochir, and Fresnelii), and I can add a fifth (Figure 1), in which the second pair of feet bears upon one side a small hand of the usual structure, and on the other an enormous clasp-forceps This want of symmetry is something so unusual among the Amphipoda, and the structure... species of the genera Leucothoe, Cyrtophium and Amphilochus, in which genera it was missed by Savigny, Dana and Spence Bate—that a species proved by the form of the Epimera (Coxae Sp B.) of the caudal feet (uropoda Westw.), etc., to be a true Amphithoe* possesses it (* I accept this and all the other genera of Amphipoda here mentioned, with the limits given to them by Spence Bate ('Catalogue of Amphipodous... service by conscientiously expressing his conviction." To the desire expressed in these words I respond, for my own part, with the more pleasure, as this furnishes me with an opportunity of publicly giving expression in words to the thanks which I feel most deeply to be due from me to Darwin for the instructions and suggestions for which I am so deeply indebted to his book Accordingly I throw this sand-grain... the period of tormenting doubt and this was by no means a short one—when the pointer of the scales oscillated before me in perfect uncertainty between the pro and the con, and when any fact leading to a quick decision would have been most welcome to me, I took no small pains to detect some such contradictions among the inferences as to the class of Crustacea furnished by the Darwinian theory But I found... genealogical tree, whether for the families of a class, the genera of a large family, or for the species of an extensive genus, and to produce pictures as complete and intelligible as possible of the common ancestors of the various smaller and larger circles, might furnish a result in three different ways 1 In the first place, Darwin's suppositions when thus applied might lead to irreconcilable and contradictory .
