While under the management of the Ohio State University, it is desired to make the laboratory as useful as possible to instructors and investigators in biology, wherever located. To this end table room is granted free of charge to qualified investigators, and any one wishing to undertake investigation of biological problems will be given all possible opportunity. Courses of study have been designed especially for high school teachers and for advanced university students, the former devoting themselves to methods of field work and preservation of material for laboratory use, and acquiring methods of laboratory work in connection with study of typical forms. For the latter, advanced courses in embryology, morphology, entomology, plant ecology, botany, etc., are offered. The students taking such courses can secure for them university credits covering equivalent courses in the university curriculum. It is needless to say that the opportunities for field observation, collecting, and the laboratory study of representative forms are most favorable. For special advanced courses in embryology, and particularly those pertaining to microscopical technique, the more elaborate equipment of the university is of course preferable. NOTES ON THE FLORA OF SANDUSKY. W. A. KELLERMAN. The visitor or student at the Lake Laboratory will find in the neighborhood of Sandusky a flora in many respects peculiar and richer in species perhaps than in any other region of similar area in the state of Ohio. For our knowledge of the Sandusky plants we are indebted mainly to the continued and energetic explorations of E. L. Moseley, teacher of botany in the Sandusky High School. Our visits to the region have been numerous, and many weeks have been spent in herborizing during the last few seasons. Mr. Moseley’s Sandusky Flora (Ohio State Academy of Science, Special Papers No. 1) and additions by myself and Mr. Griggs reported before the Academy of Science, and published in THE OHIO NATURALIST, Vol. 1, fully represent our knowledge of this interesting flora to date. In the “Sandusky Flora,” page 2, Mr. Moseley states that “the surpassing richness of the Sandusky flora is not due to the fact that it includes islands within its territory, for scarcely any of its species are confined to the islands; nor is it in a very large measure due to the fact that it includes species that are confined to the lake shore; but rather to peculiarities of climate and geological features, both of which depend to some extent on the proximity of the lake.” [Illustration: _Plate 7._ AT THE BOAT LANDING. ]
