Lime is one of the elements essential for plantgrowth, its chief function being to render poisonous oxalic acid harmlessby conversion into insoluble calcium oxalate. Monoclinic, or rarelytetragonal, crystals of this salt occur in certain tissues, and arc often ofgreat service in diagnosis. Four distinct forms deserve special mention:(i) cr)stal clusters or rosettes (Fig. 8, b and c), (2) large single crystals(Fig. 8, a), (3) raphides or nee(lle-shai)ed crystals (Fig. 9), and (4) crystalsand or deposits of numerous minute crystals (Fig. 10). THE PRINCIPAL HISTOLOGICAL ELEMENTS. 27 Calcium oxalate is distinguished from all other crystalline substancesby its insolubility in water, alkali, and acetic acid, its solubility without
