Upon standing, the ethereal extract deposits a granular substance which 
can be obtained quite pure by pouring off the supernatant oily layer and 
washing the deposit rapidly with ether. The washed precipitate, dis¬ 
solved in ether, crystallizes, upon evaporation, in rhombic leaflets, m. p. 
160°C, insoluble in alcohol or water. The crystals were not obtained in a 
sufficient degree of purity to determine their chemical constitution.

The report includes a reprint of Procter’s paper on the ethereal ex¬
