THE ESSENTIAL DUCTLESS GLANDS 241 
Just a few more words in conclusion: Endocrinology 
is yet in its infancy. The mysteries of the ductless 
glands and their hormones have just begun to be un- 
raveled. Exact knowledge on their relations to each 
other, is still awaiting the tireless investigators, who 
will find in this work unlimited opportunities for great 
discoveries.
