MAY MEETING. The Biological Club met in Zoological Lecture Room May 6, 1901. Professor Schaffner reported that the committee appointed to consider the disposition to make of exchanges, had had a meeting and appointed Professor Osborn to consider the matter further. Professor Landacre gave a paper entitled A Study of Passalus Cornutus. He gave the more important conclusions he had arrived at, after an extended study of the muscular and skeletal systems of that beetle. Mr. Griggs read a paper on Vernation in the Willows. Moulds and other Fungi Injurious to Foods was the title of a paper given by Miss Mary Dresbach. She gave a list of fungi found on food products. In discussing this paper Professor Schaffner said the moulds are of public interest and many important results may be expected from an extended study of them. Professor Kellerman said that moulds are an important factor to guard against in canning fruit. It would be a great step in advance if fruit could be canned and kept without its being cooked beforehand. Miss Elma Perry gave a list of the edible fungi of Ohio. So far 200 species have been recorded and there are no doubt many yet to add. Under the head of personal observations Prof. Kellerman showed some interesting variations in our common anemone. A paper on this subject appeared in the May number of THE OHIO NATURALIST. JUNE MEETING. The June meeting of the club was held in Zoological Lecture Room on the evening of the third. The editor-in-chief of THE OHIO NATURALIST, Professor Schaffner, gave a financial statement for the year. The Secretary read a communication from Professor Kellerman. This communication was concerned with the past and future of THE OHIO NATURALIST and an adjourned meeting was voted for its consideration. The following invitation was received from Professor W. D. Gibbs, Secretary of the Omega Chapter of the Society of Sigma Xi:
