Care was taken to thoroughly empty the udder both by aspira- 
tion and by rhythmic external compression of the gland. The 
intra- venous injection of infundibulin starts the flow in about one 
minute from the beginning of the injection, and it reaches its 
height in four minutes, after which it rapidly falls to normal.

The galactagogue action of the thymus and corpus luteum. 
By ISAAC OTT and JOHN 0. SCOTT. 
[From the Physiological Laboratory, Medico-Chirurgical College of 
Philadelphia.] 
In experiments upon the goat with the glands containing in- 
ternal secretions, we have found the corpus luteum, pineal body 
and thymus increased the quantity of milk fourfold in five minutes. 
The ovary minus corpus luteum had no effect. Infundibulin is 
still the most powerful galactagogue, increasing the secretion of 
milk one-hundredfold. The amount of butter fat was about the 
same in the augmented secretion by thymus, corpus luteum, and 
infundibulin, but occasionally it was increased.
