![references to the literature of the subject in the body of the work. Anything like consistent historical treatment would be out of place in an elementary book; and the introduction of casual references to particular discoveries, while they might interest the more advanced reader by giving a kind of personal colouring to the subject, could hardly fail, from their necessarily limited character, to be misleading to the beginner, and to increase rather than diminish his difficulties. We have, therefore, postponed all reference to the history of the science to the concluding Section, in which the main lines of progress are set forth, and have given, as an Appendix, a guide to the modern literature of Zoology. The latter is intended merely to indicate the next step to be taken by the student who wishes to acquire something more than a mere text-book knowledge.1 The various Sections have been written by the authors in fairly equal proportions, but the work of each has been carefully read and criticised by the other, and no disputed point has been allowed to stand without thorough discussion. We are therefore jointly and severally responsible for the whole work. A very large proportion of the figures have been specially drawn and engraved for the book. Those in which no source is named are from our own drawings, with the exception of Figs. 571, 572, 1017, 1018, 1019, 1022, 1059, 1063, and 1071, for which we are indebted to Mrs. W. A. Haswell. Figs. 1002 bis, 1005 bis, are from photographs kindly taken for us by Mr. A. Hamilton.2 Many blocks have been borrowed from well-known works, to the authors and publishers of which we beg to return our sincere acknowledg¬ ments. All the new figures have been drawn by Mr. M. P. Parker. 1 In this connection we cannot resist the pleasure of quoting two passages, exactly expressing our own views, from the preface to Dr. Waller’s Human Physiology, which came under our notice after the above paragraph was in type — 1 have given a Bibliography after some hesitation, feeling that references to original papers are of no use to junior students, and must be too imperfect to lie satisfactory to more advanced students. . . . Attention has been paid to recent work, but I have felt that the gradually-formed deposit of accepted know¬ ledge must be of greater intrinsic value than the latest ‘ discovery ’ or the newest theory. An early mental diet in which these items are predominant is an unwholesome diet ; their function in elementary instruction is that of condi¬ ments, valuable only in conjunction Avith a foundation of solid food.” 2 The figures referred to are numbered 608, 609, 1080, 1081, 1082, 1085, ] 128, 1132, 1140, 1063, and 1067 in the neAV edition.](https://iiif.wellcomecollection.org/image/b31360671_0001_0012.jp2/full/800%2C/0/default.jpg)
