THE INTERRELATIONSHIP OF THE INTERNAL 
SECRETIONS 
By R. J. StrouD, M.D., Douglas, Ariz. 
The effect of impairment or removal of certain endo- 
crine glands has been known for many years, but their 
relationship to one another and to the whole series of 
internal secretions produced has been neglected until 
very recently. For many years before Brown-Séquard’s 
work the subject of endocrinology was either in dis- 
repute or considered of no particular importance. All 
of the textbooks on physiology were barren of the sub- 
ject except in a cursory way. All had recognized the 
effects of castration on both young and older subjects, 
but when the subject was first revived by Brown- 
Séquard’s remarkable report (in 1889), the stimulus 
was killed, as charlatans found their pocketbooks en- 
riched by the advertising of gonadal substances about 
which the whole profession was talking. History has a 
habit of repeating itself, and this same thing seems to 
be happening right now. 
When real charlatans use any method unscientifically 
the profession, as a whole, condemns the procedure, 
whether there is any merit in it or not. It is then for- 
gotten until revived. The more recent interest in 
“monkey gland” treatment is simply a revival of the 
work done in France some thirty years ago. It is with- 
in the memory of 9 great many physicians that iodine 
fell into disrepute when the laity began extolling its 
virtues, but it has revived in greater measure than
