350 S. F. Peckham on California Petroleum. 
um examined by Messrs. Silliman, Warren and Maisch, with 
those of the samples of Southern California petroleum, examine 
by myself, exhibits the following very marked and important 
differences. 
Consistence differing, as water and olive oil. 
The odor of one is strikingly similar to that of refined Penn- 
sylvania petroleum; that of the others without resemblance 
thereto, and peculiar though not offensive. 
"he density of the one is ‘(020—=5° Baumé, lighter than any 
oil that could possibly have been procured in that region prior 
to July, 1865. 
The boiling point of the one is 50° C. below, and the sp. gr. 
of 1st 10 per cent of distillate from the same is ‘050 below that 
of the other. 
further a by the fact, that the lightest oils obtained from the 
she falsification consisted in the addition of an equal portion of,

3°5 per cent of distillate, of sp. gr. 48° B.=810. The results 
obtained by Mr. Warren were equivalent to about 55 per cent 
of the same grade. This slight increase is a natural result of
