Leucin apjDcars in the formof plates of various sizes, and with a weak opalescence; tyrosin,in that of slender sheaves and rosettes. Leucin is especially found in the glandular organs of the body,and, with tyrosin, is a constant product of the resolution of thealbuminates and nitrogenous substances. Their recognition in theurine is mainly based on microscopic examination. PLATE 24. Mezger Ulli Leucine and tyrosine, Peyers microscopy. PLATE 25, 52 CLINICAL MICROSCOPY. CYSTIN Is not found in normal urine; only in tlie sediment, where cystinstones occur. Still, cystinuria may exceptionally exist withoutthem. It crystallizes in the form of regular hexagonal tables,some of which are piled on each other. It may be distinguishedfrom the similar tables of uric acid by its insolubility in muriaticacid. Cystinuria is found more frequently in the male sex than in thefemale, mostly in earher life, becoming more rare in advancedyears. The excretion varies in degree, and may at times entirelycease. It has been ascertained that in a family generally severalmembers suffered from the disease. Our table represents the urine of a gentleman sixty years ofage, who otherwise is a picture of health; he has suffered since hisyouth from cystinuria, with repeated passage of cystic stones undercohcky pains. He has had no colics these five years, but severalattacks of regular gout. Gout an
