PREFACE 



subjects have been increased very considerably and this, it is 

 hoped, will make the book more useful to students and 

 practitioners. Many of the new illustrations are photographs 

 of patients suffering from diseases of the organs of internal 

 secretion. 



The nucleus of the book was an article in the Ergebnisse der 

 Physiologic, and I have to thank the Editor, Professor Asher, 

 of Bern, and the publisher, for their courtesy in allowing me to 

 use the material as the basis of the present work. 



Many of the illustrations are derived from papers contributed 

 to various journals from time to time, either by myself, or by 

 or in conjunction with pupils and others working under my 

 direction. A large number have been drawn for me by the 

 late Mrs. F. D. Thompson, of the University of Manitoba. 

 The figures specially drawn by her for the present work are 

 Nos. 13, 13a, 29, 56, 91, 92, 93, 95, 104 and 105, while Nos. 9, 

 10, 11, 57, 77, 79, 80 and 81 were drawn by her to illustrate her 

 paper in the Phil. Trans., 1910. 



Most of the tracings have been taken from papers by myself 

 or conjointly produced in the Journal of Physiology and 

 Endocrinology, and I have to thank Professor Langley for 

 supplying cliches of blocks of many of those published in the 

 former journal. Some of the tracings have, however, been 

 taken from the records of class demonstrations (Figs. 39-43) 

 or from unpublished work in my laboratory (Fig. 46). Figs. 

 58 and 59 were drawn by Mr. Carmichael from sketches kindly 

 furnished by Professor Evatt. 



Diagrams A and B of Figs. 82 and 90 are taken from a paper 

 by Dr. Kohn, of Prag. Figs. 20, 23, 24 and 26 are taken from 

 papers by Giacomini, Fig. 21 from Diamare, and Fig. 22 from 

 Kohn. Figs. 83-86 are borrowed from Murray (Diseases of the 

 Thyroid Gland. London, H. K. Lewis, 1900). Fig. 87 from 

 Adami (Text-book of Pathology. Lea and Febiger). Figs. 88 

 and 89 are taken from a paper by Sutherland Simpson. Fig. 

 98 is a photograph kindly supplied by Dr. Harvey Gushing, 

 while Figs. 99, 100, 101, 102 and 103 are taken from Cushing's 

 book on the Pituitary. l For all these I beg to express my best 

 thanks, to both author and publish IT. 



I have to thank Professors A. T. Cameron and Charles H. 

 O'Donoghue of the University of Manitoba for much assistance,
