trious Frenchman. A new impetus was given the 

 subject, and glandular treatment became the hope 

 of a world full of maladies. 



Despite an enormous amount of work, it cannot 

 be said that we have accomplished much with glan- 

 dular extracts beyond their use in thyroid disease. 

 Pituitary extracts have had a measure of success 

 in pituitary disorders, but not comparable to the 

 corresponding extract from the thyroid when ap- 

 plied to cases of hypo-thyroidism. 



With a persistence worthy of some admiration, 

 glandular advocates, failing to get results with any 

 one extract, tried each one of the others in turn. 

 Still without result, they adopted pluriglandular 

 treatment that is to say, treatment by the use of 

 extracts from several glands. It cannot be said 

 that these methods yielded any better results. 



Now the question may very naturally be asked, 

 why should thyroid extract be of service in hypo- 

 thyroidism, and why should extracts from other 

 glands be of so little service in other diseases due 

 to glandular insufficiency? We do not know, 

 though we can speculate as to the cause. Are we 

 to assume that only the thyroid hormone is resistive 

 enough to escape all dangers and reach its desti- 

 nation safely, whereas other hormones are de- 

 stroyed on the way? 1 This is not a likely hypothe- 



1 "No assumption is needed in this case any longer, because we 

 now know that thyroxin is of a very different nature from any
