November 4th, 1901. The Biological Club met in Orton Hall and was called to order by the president, Prof. Osborn. As it is customary to elect new officers at the November meeting each year, the Nominating Committee presented the following names: For president, Mr. Mills; for vice-president, Mr. Morse; for secretary, Mr. Tyler. Prof. Lazenby moved that the secretary be instructed to cast the unanimous ballot of the members present for the names proposed. Carried. Messrs. J. C. Bridwell, M. T. Cook and Harvey Brugger were elected members. The retiring president, Prof. Osborn, presented a very interesting address, an abstract of which follows: SCOPE OF MODERN BIOLOGY. It has been the custom in this society, following a mandate of its constitution, for the president on retiring from the chair to give an address, and it is presumed that such an address will either bring to your attention the results of some special investigation, summarize the work in some field of research or outline the progress and problems with which biology has to do. When a year ago you were so kind as to honor me with this office, two things I think came especially to my mind; one the success of the club particularly in the new enterprise of publishing a journal; the other the duty, honor and privilege of preparing an address for this occasion. I presume you have all had the experience of contemplating some distance in the future a certain duty, debating the most suitable theme or method, and perhaps seen the time grow shorter and shorter with little real accomplishment. If I were to enumerate the various topics that have come to my mind as suitable for this occasion it would exhaust quite a part of our time; if I could reproduce the current of thought that has flowed from time to time along the pathways of such topics, I am sure you would experience a weariness that I should regret to occasion.
