One aphis is found alive held to the stem of the plant by a pasty mass of yeast. May 16. — Only three aphides alive ; the mold has seriously injured the plant. Experiment No. 6. — May 26. — Sowed yeast from the same bakery as in No. 5 upon the aphides on a healthy young plant of same kind and size as No. 4. This time the plant was not treated differently from others in the same room except being thoroughly sprinkled with yeast. June 3. — Aphides as numerous as ever. No dead ones seen. Experimen...t No. 7. — To ascertain whether any fungoid growths could be developed from the dead aphides in No. 5, two of them are placed on a bit of clean, broken plant crock sufficiently moist- ened, which is covered with a small bell glass, the rim of which rests in a shallow vessel of water to isolate the experiment as completely as possible. The experiment commences May 5, at 2 p. M. On May 6, at 3.30 p. m., some mycelium is visible on the body of an aphis. May 9. — A number of upright hyphae have fruited ; the quantity of fruit is very small and not sufficient to determine what the mold is with certainty, but it appears to be a Mucor.
