![CULTIVATION OF ORDINARY STOOL. 15 between the free cells and the imperfectly detached set?- ments of mycelium. The watch-glass was replaced in the apparatus for a fortnight, bnt no change took place. Prom these illustrations it will be seen that whereas cysts, distinctly resembling those described by Professor Hallier, may, by cultwation, be observed to develop in chole- raic discharges, yet they are by no means constantly obtain- able, for out of more than a hundred cultivations, made with the express object of developing these cysts, only three times was I able to produce any fungi bearing such tokens of fructification. Is it possible to develoj) fungi in other than cholera dejections bearing fruit resembling the cholera cyst ? The answer must be Yes, as the following experiment mil show :— Illustration V:— About half an ounce of faeces, obtained from a perfectly healthy person, was placed on a .faurrol oleTsoS ^]^^^ pl^^c, and carefuUy trans- and tke other exposed. lerrcd mto the bcll-glass of the isolating apparatus in connection with the aspirator, as ah^eady described, the greatest possible care having been taken to prevent foreign matter coming mto contact with it before depositing it on the stage in the apparatus. A small portion of the same substance was placed on a glass slide, without any special precautionary measm-es being taken to prevent access of foreign matter, so as to be able to examine it from day to day for comparison with the preparation in the bell-glass, which it was not mtended to disturb. On the second day a few small white spots were observed on both preparations, one of which was Progress Of exposedprepar- Pi^ted out with a needle from the ation. non-isolated mass, and placed on the . p . ^ ^^^^ microscope.
