Microscopic characters of cystine.—These are sowell marked and easily recognised, that the microscopicexamination of a sediment composed of cystine, ren-ders the application of tests unnecessary. When an ammoniacal solution of cystine is allowedto evaporate spontaneously on a piece of glass, it leavescrystals in the form of six-sided laminae (Fig. 31).These are probably exceedingly short hexagonal the evaporation is slowly and carefully performed,.
