PREFACE TO THE_ENGLISH EDITION. 



An Ensflish Edition of von Xoorden's well-known "Lehrbuch 

 Stoffwechsel" does not require any sf)ecific introduction. 



Although the arrangement of the sections and their contents is 

 the same as that of the first edition, the present text is mainly due 

 to the co-operation of a number of workers in this branch of 

 Medical Science. In his preface to the first German Edition, 

 von Noorden acknowledged the encouragement and assistance of 

 Gerhardt, von Jurgensen and Riegel ; in his introduction ^o the 

 second edition, he expresses his grateful thanks to the collabora- 

 tors, ''whose unflagging and zealous work alone has made it possi- 

 ble to bring out. instead of a second edition of my text-book, a 

 hand-book of the pathology of metabolism" worthy of the extent 

 and importance of the subject. 



The length and style of the German original has restricted the 

 addition of the more recent work in detail. The additions made 

 to both the text and bibliography have conformed to the general 

 principle of the work in presenting a compilation of facts and a 

 critical discussion of hypothesis rather than the enunciation of 

 theories ; they have also been selected in harmony with the view 

 of von Noorden and others, that experiments upon animals should 

 be cited only in connection with acute conditions ; as it is so difficult 

 to compare them with the conditions which obtain in the chronic 

 diseases of human beings, these addenda have been incorporated 

 in the text. 



It is a pleasure to express my thanks to my colleagues for 

 their translations, to iny friend Professor T. H. ]\Iilroy, for the 

 many valuable suggestions and to the University College Demon- 

 strator in Pathology, Dr. Carey Coombs, for his careful prepara- 

 tion of the indices.
