yellow colour and bitter. This extract, treated with 60 per cent. 
alcohol, left a small amount of white residue, which had the 
character of a wax. The aqueous solution of the soap, after: 
separation of the ether, was heated for some time to remove dis- — 
solved ether, the solution was then mixed with dilute sulphuric 
acid in excess, and the insoluble separated from the soluble fat 
acidsin the manner recommended by Allen.* he soluble fatty 
_ acids amounted to 3-519 per cent., the insoluble to 89-128 per 
cent. The volatile acids consisted of butyric and a trace of 
valeric acid. During the distillation to separate the fluid from 
~ the volatile fatty acids, a small amount of a show white fatty acid 
passed over; this acid had a melting point of 43°6° C., which 
corresponds with the fusing point of lauric acid.’ A weighed 
- portion of the insoluble fatty acids, from which the iauric acid 
had not been separated, was dissolved in alcohol, and titrated 
with normal standard soda, using phenolphthalein as an 
indicator, *288 gram of the acids required l c.c. of caustic soda 
for neutralization. No attempt at separating the fixed fatty 
acids was made; they probably consisted of a mixture of 
stearic and oleic acids, with a small amount of lauric acid. 
Examined by Reichert’s distillation process, 2°5 grams of the 
_ oil-gave a distillate which after separation of the lauric acid, 
_ which had distilled over, required 4°6 c.c. of decinormal soda 
for neutralization, phenolphthalein being used as an indicator. 
i ene saponification. equivalent of the oil was determined by 
_ Koettstorfer’s method, and was equal to 284, the percentage of 
caustic potash required to saponify the oil being 19°72. 
A preliminary examination of the oil having indicated the 
ae presence of sulphur, a quantitative estimation of the amount 
present was made and found equal to -427 per cent. The oil 
_ after repeated agitation with peor! was, found to contain only 
- *109 per cent. of sulphur.
