When cystine occurs as a sediment, it is alwayscrystallised, never under any circumstances beingamorphous. Among the crystals a few regular six-sided laminae are often seen, but the great mass iscomposed of a large number of superposed plates, sothat the compound crystals thus produced appear mult-angular, as if sharply crenate at the margin; and thewhole surface is traversed by lines, which are really theedges of separate crystals (Fig. 32). They thus resemblelittle white rosettes, when viewed by reflected compound crystals always appear darker in thecentre than at the circ
