In harmony with this hj^othesis a nema- tode parasite, Heterakis papulosa, occurring in the ceca of turkeys, chickens, and some other birds, was brought into the experiment as the possible associated factor. Experiment 5. — This experiment consisted in feeding to young turkeys embryo- nated eggs of Heterakis papulosa and feces from adult turkeys. Worms were col- lected from the ceca of healthy chickens, killed for this purpose, by washing and sedimenting the contents and picking out the worms. ...These were cut up in a small quantity of normal salt solution to liberate the ova. The suspension was kept in Petri dishes at room temperature and distilled water added from time to time to make up for evaporation. After the cultures had been kept for 17 days, examination showed that the ova contained Uving embryos. On Sept. 11 they were added to the feed of two tur- keys which had been used in the preceding experiment. To ensure the com- plete mgestion of the mixture the turkeys were placed in a cage.
