The Loss of the Lapham Collection.—One of the most serious losses in the recent fire at the Wisconsin State University was the scientific collection made by Dr. I. A. Lapham, and purchased after his death by the State. It consisted of a cabinet containing fossils, minerals, shells, meteorites, and Indian antiquities, 10,000 specimens in all, besides duplicates for exchange; an herbarium of 24,000 specimens, belonging to 8,000 species; and a library of about 1,500 books, pamphlets, and maps. Among the books were many rare volumes. The geological specimens included a large number of fossils peculiar to American formations, and a full series of rocks and fossils illustrating in perfect order and with perfect clearness the geology of Wisconsin. The herbarium embraced the whole range of the vegetable kingdom, with a similar treatment for all examples from the highest to the lowest. Many of the specimens were obtained by exchange from the most eminent botanists in America, England, France, and Germany.

Flowering Plants as Ozone-Generators.—Dr. J. M. Anders has published, in the "American Naturalist," descriptions of experiments he has made in the relations of plant-growth with the generation of ozone. Among the conclusions he has reached are, that the leaves have nothing to do with the production, but that the function resides with the flower; that it lies predominantly ill odorous flowers, inodorous flowers being poor generators; and that sunlight, or at least good diffused light, is essential to the production. Hence, it is inferred, during fair weather all flowering vegetation is con-
