* PREFACE. 



acknowledge my indebtedness to many valuable Papers in the various 

 Medical Journals British and Foreign and also to the Histological 

 Treatises of Cadiat, Ranvier, and Klein ; Quain's Anatomy, vol. II., ninth 

 edition- Hermann's Hanclbuch der Physiologic; and the Text-books on 

 Physiology by Rutherford, Foster, and Kirkes ; Gamgee's Physiological 

 Chemistry ; Ewald's Digestion; and Roberts's Digestive Ferments. 



(3.) The Illustrations have been greatly increased in number, viz., 

 from 275 in the Fourth German Edition to 494 in the English version. 

 These additional Diagrams, with the sources whence derived, are dis- 

 tinguished in the List of Woodcuts by an asterisk. 



There only remains for me now to express my thanks to all who 

 have kindly helped in the progress of the work, either by furnishing 

 "illustrations or otherwise especially to Drs Byrom Bramwell, Dudgeon, 

 Lauder Brunton, and Knott ; Mr Hawksley ; Professors Hamilton and 

 M'Kendrick ; to my esteemed teacher and friend, Professor Ludwig, of 

 Leipzic ; and, finally, to my friend, Mr A. W. Robertson, M.A., formerly 

 Assistant Librarian in the University, and now Librarian of the Aberdeen 

 Public Library, for much valuable assistance while the work was passing 

 through the press. 



In conclusion and forgetting for the moment my own connection 

 with it I heartily commend the work per sc to the attention of Medical 

 Men, and can wish for it no better fate than that it may speedily become 

 as popular in this country as it is in its Fatherland.
