They are spar-ingly found in trichocephalus, and they were totally absent inthe cases of tenia nana so rarely observed in Germany (Leich-tenstern). According to this author, in every case in whichCharcots crystals are found in the feces the presence of worms. Fig. 23.—Penningtons Proctoscope. should be assumed as very probable. On the other hand, theabsence of the crystals does not preclude helminthiasis. The fact that the crystals are most numerous in that por-tion of the intestine in which anchylostomum is usually located{upper ileum, not ditodenwn); that they are very abundant inthe slimy, bile-stained stools induced by drastica in anguillu-liasis; that their appearance, even though seldom, in the stools EXAMINATION 59 some time after an anthelmintic course has been pursued al-ways points to incomplete expulsion of worms (retention ofthe particularly tenacious male anchylostomum, or of tape-worm head), all indicate that the crystals are formed at theseat of the parasites (Leichtenstern).
