INTERRELATIONS OF SECRETIONS 47 
Male, aged 41, height 5 feet 8 inches, and weight 119 
pounds, gave the history of dysentery three months 
previous, which was severe. He was ill in bed two 
months, and since that time had been under the care 
of a physician who had prescribed tonics by mouth and 
had also given them hypodermically. Despite this 
treatment he had not gained in weight and his mental 
attitude was hopeless, as he wanted to take out some 
life insurance and knew his physical condition would 
be against it. Examination showed all organs nor- 
mal except the apex beat, which was “‘soft.’”’ The blood 
pressure showed the cause of the trouble. The read- 
ings: Systolic, 105; diastolic, 80 mm. The stimulat- 
ing tonics were discontinued and a _ pluriglandular 
formula was given for two months. At this time the 
systolic pressure was 127 mm., and he weighed 147 
pounds. 
His despondency has now left him, and he has not 
yet, after one year, taken out life insurance. The 
necessity of “protection” for his family left him as soon 
as the well-being was restored, due to the reestablish- 
ment of the normal endocrine balance. He also stated 
that his libido had been increased, which demonstrated 
the broader effect of the stimulation from the pluri- 
glandular extract. 
Nature, by selective action, always tries to maintain 
the endocrine balance. If one organ is impaired the 
co-operative selective action of the other glands helps 
to keep the balance by making use of the allied secre- 
tions where possible. At other times the function of 
other glands is increased to make up deficiency. If 
this close relationship were not maintained, the balance 
would be very easily shaken and comparatively slight 
disturbance of any of the organs would lead to notice- 
able clinical symptoms. The results of endocrine un- 
derproduction or overproduction would be felt imme- 
diately. This hormonic action of one gland upon an- 
other is in relationship with all glands, whether these 
glands produce endocrine substances which augment 
their action, or whether they counteract it. Only in
