Therapeutic Work. In 1912 I experimented with 
thymol and sodium cacodylate in an attempt to cure 
some of the quarantined and useless parrots. This 
time, having three toucans, I decided to try another 
arsenical preparation with the thymol, namely arsphen- 
amine. Preliminary tests as to dosage on pigeons 
showed that they could tolerate enormous amounts, 
^. e., up to 0.0375 gm. intravenously. This is, weight 
for weight, about six times the human dosage. 
A corresponding dose of arsphenamine was then ad- 
ministered to the one surviving toucan (two had died 
during the preliminary pigeon work) together with thy- 
mol by mouth. The bird was a poor specimen and died 
in about 20 minutes. Autopsy showed the spiroptera 
deeply imbedded in the proventricular mucosa. All 
were translucent from the effects of the glycerine in which 
the thymol had been administered and were motionless. 
That is, the glycerine, which must have been saturated 
with thymol, had penetrated the mucosa sufficiently to 
saturate the worms. In about 20 minutes more the 
worms were pulled out and placed in warm salt solution 
over night. Next morning they were actively moving. 
Without further speculation as to what might have 
happened under other circumstances (longer exposure 
to thymol, etc.,) suffice it to say that again we are con- 
strained to remark on the difficulty of animal medication.

is the seat of a small very thin walled cyst one-half inch 
in diameter also containing clear fluid.
