They are more commonly found in the urine of females, starchpowders being extensively used for dusting purposes, but individual glob-ules from the underwear are also seen. They are oval or round, highlyrefractive, and vary greatly in size, with a more or less central hilum orumbilicus, around which are concentric striations. The hilum may beeither round, oval, or irregular, at times quite large, at times small, andoccasionally appearing as if split. The different varieties of starch, although having the same character-istics, vary in shape as well as in size. The three most frequently found.

Rice starchalways appears in the form of oval or oblong, quite regular globules ofmedium size. Corn starch is smaller, irregular, at times almost hexag-onal, and contains an irregular hilum. Wheat starch consists oflarge globules, as well as of small, irregular formations, in which latterthe hilum may be entirely absent or is present only in the form of adot. Lycopodium (see Fig. 95).—Lycopodium, somewhat similar to starch,and also considerably used for dusting purposes, consists of globularformations of different sizes, with a distinct shell, and studded with pe- V M Seventh Revised and Enlarged Edition.
