SOME NOTES ON BOOKS. 



Those for whom this volume is primarily intended, — students who 

 are beginning the study of Zoology as part of a scientific and medical 

 curriculum, will find the following four books of great service : — F. 

 Jeffrey Bell's Comparative Anatomy and Physiology (Lond. 1887); 

 C. Lloyd Morgan's Animal Biology (Lond. 1889); A Course of Ele- 

 mentary Instruction in Practical Biology, by T. H. Huxley and H. N. 

 Martin, revised edition by G. B. Howes and D. H. Scott (Lond. 

 1 888) ; and A Course of Practical Zoology, by A. Milnes Marshall and 

 C. H. Hurst, and Ed. (Lond. 1888). 



Among text-books, Huxley's two volumes on the Anatomy of Inverte- 

 brate and Vertebrated Animals (Lond. 1877 and 1871), occupy the 

 highest plane, but they require to be re-edited. Useful in particular 

 ways are the works of Claus, GrundzUge der Zoologie, Marburg, 1880-2 

 (untranslated), and his smaller texl-book (trans, by A. Sedgwick, 2 vols., 

 Lond. 1884-5), and the text-books of A. S. Packard, and of H. AUeyne 

 Nicholson. As a modern introduction to the problems of classification, 

 W. A. Herdman's Phylogenetic Classification of Animals (Lond. 1885) 

 will be found at once terse and clear. 



Works on Comparative Anatomy : — Gegenbaur's (trans, by F. Jeffrey 

 Bell, Lond. 1878) ; Wiedersheim's (trans, by W. N. Parker, Lond. 

 1886), and his unabridged and untranslated volume ; I^ang's re-edition 

 of O. Schmidt's Vergleichende Anatomic (in progress, Jena, and being 

 translated) ; Hatschek's smaller work (also in progress, Jena, and un- 

 translated). A treatise on comparative physiology is hardly possible at 

 present, but the senior student should make himself acquainted with 

 Krukenberg's Vergleichend- Physiologische Studien and for/rnj-,? (Heidel- 

 berg, 1881-9). 



For the practical study of 'Invertebrates, we have now a complete 

 manual in French or German, by Vogt and Yung ( Trait^ d' Anatomic 

 comparSe pratique (Paris 1885-90) ; or Lehrbuch der praktischen Ver- 

 gleichenden Anatomic (Braunschweig 1885-90), which is being Antinued 

 by a similar treatment of Vertebrates. W. K. Brooks' Handbook of 

 Invertebrate Zoology, for Laboratories and Sea-side Work (Boston, 1882), 

 is very valuable. T. J. Parker's Zootomy (Lond. 1884), is indispensable 

 to those who wish to make a thorough practical study of the common 

 vertebrate types.
