In its dimensions _S. floridana_ is intermediate between _S. stictica_ (Eng. Bot.) Wille and _S. ceylanica_ Wittrock. In several publications the statement is made that _S. ceylanica_ is intermediate between _S. stictica_ and the common forms of _Spirogyra_. A study of authentic material of this species has shown that it has not intermediate characters, but with its spores having a minutely pitted median wall, it seems to be intermediate between _S. floridana_ and _S. illinoiensis_ Transeau, the most specialized form in the Sirogonium group of the genus. Throughout the study of these collections the writer has been greatly assisted by Mr. Hanford Tiffany, now a teacher in the Charleston, Illinois, High School. It is a pleasure to acknowledge my indebtedness to the many collectors who have sent me specimens for study. ORGANIZATION OF THE OHIO STATE UNIVERSITY SCIENTIFIC SOCIETY. As the result of the sentiment expressed at the 1914 meeting of the Ohio Academy of Science that the official organ of the Academy, “The Ohio Naturalist,” should be broadened and made more comprehensive in scope, and feeling that the Ohio State University had no publication representing the scientific work being done at the institution, the members of the Biological Club of the University, in whom the publication of the “Ohio Naturalist” had been vested, called a meeting of representatives of the various departments interested in science at the university to discuss the advisability of publishing as successor to the “Naturalist” a journal to be known as the OHIO JOURNAL OF SCIENCE. The first meeting was held in May, 1915, and committees appointed to outline preliminary plans. At subsequent meetings the reports of the committees were discussed, interest in the plan continued to develop, until at a meeting held October 13 the following self-explanatory Constitution was adopted. The society as now constituted represents twenty-four departments of pure or applied science at the university. RAYMOND J. SEYMOUR, Secretary Pro Tem. CONSTITUTION. ARTICLE I—NAME.
