been completely sterilized by exposure to a temperature of 105 deg. for ten
minutes. The India-rubber tubing he had used was steamed. Carbolic acid
solution must contain at least 5 per cent, of carbolic acid to be fatal
to bacteria. He was quite aware of the importance of distinguishing
between the action of the substances on various kinds of bacteria, and
was quite prepared to admit that a treatment which would be fatal to one
kind of bacterium might not injure another.

ON THE COMPOSITION OF ELEPHANTS' MILK.

[Footnote: Read before the American Chemical Society, June 3,1881.]

By CHAS. A. DOREMUS, M.D., Ph.D.


Noticing the recent advertisements in the city regarding the "Baby
Elephant," it occurred to me that perhaps no analysis of the milk
of this species of the mammalia had been recorded. This I found
corroborated, for though the milk of many animals had been subjected to
analysis, no opportunity had ever presented itself to obtain elephants'
milk.

Through the courtesy of Jas. A. Bailey I was enabled to procure samples
of the milk on several occasions.
