EXAMINATION OF CALIFORNIA TOBACCO. 
A sample of tobacco was received from J. ©. Davis, Los Angeles, Cal., 
for examination. The analysis was limited to the determination of the 
alkaloid nicotine. 
The air-dried sample contained 4.04 per cent. of nicotine, an amount 
about midway between the weak tobaccos of Havana and the stronger 
ones of Virginia and Kentucky. 
The specimen analyzed possessed good color and good smoking qual- 
ities, and was apparently a superior tobacco in all respects. 
PLEURO-PNEUMONIA—ANALYSIS OF MILK OF COW. 
A microscopical and chemical examination of the milk of a cow suffer- 
from pleuro-pnenmonia was made with the following results: The cow 
was a grade short-horn, owned by Thomas Carroll, of Alexandria, Va. 
Under the microscope a sample of the milk showed an apparent defi- 
‘ciency in fat globules, and the globules, instead of being uniformly dis- 
tributed through the liquid, appeared gathered into large groups, with 
spaces between comparatively free from globules. 
There was nothing, however, of a clotted appearance jn the milk 
(although a sample of the cream under the microscope afterwards did 
present this clotted appearance), but there wasin the milk a very marked 
difference in the distribution of the fat globules. 
The specific gravity of the milk at 15° centigrade (59° I.) was 1.033. 
The composition of the milk was as follows:
