[20] An electric oven suitable for this work, which is readily adjusted to 160 degs. C., has been made for Mr. Low and the chairman, by the Apparatus and Specialty Company, Lansing, Mich. Its size is 9-1/2 × 10 × 16 inches, and capacity 8 Petrie dishes. It gives a strong draft at constant temperature.
