After fertilization a perithecium is produced, which contains the asci, each ascus being surrounded by a delicate wall and containing eight biconvex ascospores. Asperigillus forms diastase and is capable of changing starch into dextrin and maltose. Distribution. Widely distributed in nature on mouldy hay, corn and other grains. Poisonous properties. The organism is not pathogenic but probably develops a poisonous substance which may produce disturbance. Dr. Law mentions a serious case, epizootic cerebro-spinal meningitis, in Pennsylvania, due to the feeding of mouldy timothy hay, which was badly fermented. In Cairo, Egypt, 6,000 horses and mules perished from the same cause. Michener attributes this disease to foods undergoing fermentation due to toxic fungi. Williams, of Idaho, thought also that the fermentation of alfalfa, timothy and wild grass hay produced the disease. Dr. Law says: In all probability as we learn more of the true pathology of the disease, we shall come to recognize not one, but several toxic principles, and several different affections, each with its characteristic phenomena in the somewhat indefinite affection still known as cerebro- spinal meningitis. It occurs in horses, sheep, oxen, goats, and dogs, preferably attacking the young which have not become immuned to the toxic substance. It occurs most commonly in winter and spring when animals shed the coat. Dr. Mayo, who investigated this trouble in Kansas, says that a disease known as "staggers," "mad staggers," or, as he has termed it, enzootic cerebritis, is caused by feeding corn which is attacked by Aspergillu
