It is doubtful whether theparasite is directly mischievous; but its constant association withAnchylostoma, and the readiness with which the two may be con-founded, render its recognition a matter of consequence. 3. Insects.—It requires to be noticed that insect larvae infest thestools. Joseph 1T0 has reported a number of species, which are for themost part taken into the intestine with food (cheese, meat), and giverise to a variety of morbid symptoms, as colicky pains, vomiting,&c. Special mention may be made of the immature cheese-maggot(Piophila casei) and Drosophila melanogastra, which are derived. FIG. 95.—Hfematoidin Crystals from Acholic Stools (eye-piece III., objective 8A, Reichert). from curdled milk, and may attain the chrysalis form in the intestinebefore they are discharged per rectum. Of other species are the larvaeof three varieties of Homalomyia, of Hydrothaea meteorica, Cyrtoneurastabulans, Calliphora erythrocephala, Pollenia rudis, Lucilia caesar andregina, Sarcophaga haemorrhoidalis and haematodes, and Eristalis arbus-torum, all of which are apt to occur. Rembold, Lampa, and Kohn171have also observed in the stools certain lancet-shaped bodies, 8 , which are covered with hair and indented on the surface, andthese have been identified by v. Graff as the larvae of Anthomyiae.[Finlayson172 records a case in which swarms of larvae were passed alivefrom the bowel of a man. He identified the insect as Anthomyia cani-cularis or scalaris.] Hensclien172, records a whole series of
