I HAVE read with interest Mr. Robert McKay's letter1 on the germination of oospores of Peronospora Schleideni. He notes the remarkably persistent oogonial wall, which “forms an additional protective layer” around the oospore, and the still more persistent oospore wall. In germinating these highly resistant spores he lays claim to no special method: in course of time, in this case of years, the spores germinate when placed in water.
