ORANGE OIL. 
With M. V. Rosario. 
The oil was extracted from the peel in the following manner. 
The peels were rubbed under water on a grater to disintegrate 
the oil cells, the liquid was then strained through muslin, and 
the pulp squeezed and washed with petroleum ether. The pe- 
troleum ether was added to the water, agitated, and separated. 
This was repeated with 3 portions of solvent. The petroleum 
ether portions were then united and evaporated under a pres- 
sure of 12 to 15 millimeters at a temperature below 50° until 
all of the solvent was expelled. 
The yield together with the constants of the oil are given in 
Table VII.
