1. A preliminary study of the lipins of Fenugreek seeds has been made. Methods for the isolation and fractionation of the lipins are described in detail. 2. A phospholipin allied to sphingomyelin, an oil soluble true lecithin which forms a complex with cadmium salts, a pyridine soluble galactolipin and a galactoside and a pyridine insoluble galactolipin containing sulphur are among the most interesting fractions that have been isolated from the seeds. 3. A detailed investigation of the cadmium complex and the pyridine insoluble galactolipin is under progress.
