PREFACE TO THE FIRST EDITION. vn 



I as earnestly hope that it makes plain that very much is yet 

 to be discovered. 



A work of the scope of the present volume is, of course, 

 not the proper medium for the publication of novel facts; 

 but, while the " Human Body," accordingly, professes to be 

 merely a compilation, the introduction of constant references 

 to authorities would have been out of place. I trust, how- 

 ever, that it will be found throughout imbued with the influ- 

 ence of my beloved master, Michael Foster; and on various 

 hygienic topics I have to acknowledge a special indebtedness 

 to the excellent series entitled Health Primers. 



The majority of the anatomical illustrations are from 

 Henle's Anatomie des Menschen, and a few from Arendt's 

 Schulatlas, the publishers of each furnishing electrotypes. 

 A considerable number, mainly histological, are from Quain's 

 Anatomy, and a few figures are after Bernstein, Carpenter, 

 Frey, Haeckel, Helmholtz, Huxley ? McKendrick, and Wundt. 

 About thirty, chiefly diagrammatic, were drawn specially for 

 the work. 



Quantities are throughout expressed first on the metric sys- 

 tem, their approximate equivalents in American weights and 

 measures being added in brackets,
