the dark -coloured extract warmed with acidulated water. Brown 

 resinous matter separated, and a brown, acid solution was obtained, 

 which gave slight, brown precipitates with Mayer's reagent, and with 

 a solution of iodine in potasium iodide. 



The acid solution was made slightly alkaline with ammonia 

 solution, extracted first with ether, then with chloroform. The 

 etherial and chloroformic solutions on evaporation yielded slight 

 brown residues, of a faintly bitter taste. The residue from the 

 alcohol treatment, extracted with warm water, yielded a considerable 

 quantity of mucilage, which in its impure condition gives a precipi- 

 tate both with lead acetate and lead subacetate. 



To make a thorough examination of all the constituents of both oil 

 and cake would be a lengthy operation, and would require a much 

 larger quantity of material than was at our disposal. 



I am indebted to Dr. Collie for much kindly advice in connection 

 with the foregoing experiments.
