 It gives an excellent account of its subject, supplementing Dr. Krause's paper, so that the readers of the book will be able to form not only a proper estimate of the man, but the condition of science in his time. A life of Erasmus Darwin, published in 1804, was written by a Miss Seward, but it seems to have contained certain gross misrepresentations of his character, which it is one of the objects of the present sketch to dispel. The authoress of the biography was long an inmate of Dr. Darwin's family, and when his first wife died would have been glad to take her place. But the Doctor chose another lady, and Miss Seward paid them both off in her biographical book. She subsequently retracted her objectionable statements, but the erroneous impressions, created by her book, were widely disseminated.

Mr. Darwin writes unreservedly but judicially of his grandfather's traits, and remarks that perhaps there is no safer test of a man's real character than that of his long-continued friendship with good and able men. Darwin's intimate and almost lifelong friends were such men as Josiah Wedgwood, Keir the chemist, Day, the author of "Sandford and Merton," Bolton and Watt the engineers, and Mr. Edgeworth. A fine likeness of Dr. Darwin accompanies the volume, together with engravings of his birthplace, Elston Hall, and the Breadsall Priory, near Derby, where he lived for many years, and in which he died.

reports make a volume of 541 pages, and are illustrated by numerous diagrams and maps. The detailed reports are of three counties—Wayne, Crawford, and Harrison. These, as well as special reports on clays, cements, building-stone, etc., are well written, and show thorough work. A general review of the geology of the State by Professor Cox presents his conclusions on several points of interest. Of the glacial epoch, he says: "I see no evidence of a subsidence of land to terminate the glacial period, which continued until brought to a close by its own erosive force, aided by atmospheric and meteorological influences. . . . Its force was expended in eroding, cutting down, and removing mineral matter from a higher to a lower level." He does not believe it is possible for glaciers to make erosions to so great depths "as the beds of some of the great Northern lakes." The volume contains an excellent paper on archæology, a table of altitudes, catalogues of fossils and of recent flora, and, what is of especial value, "A Catalogue and Check-list of the Trees and Woody Shrubs of America north of Mexico." This was prepared by John W. Byrkit, Esq., of Indianapolis. The volume has a very full index.

lectures make a volume of 186 pages, and are a useful contribution to the science of meteorology. The subjects are treated in a somewhat elementary manner, but in the light of the latest researches. The first, and perhaps the most important lecture of the series, is by Robert James Mann, M. D., F. R. C. S., etc., on "The Physical Properties of the Atmosphere," and is a model of lucid scientific statement. Others are on "Air Temperature, its Distribution and Range"; "The Barometer and its Uses, Wind and Storms"; "Clouds and Weather Signs"; "Rain, Snow, Hail, and Atmospheric Electricity"; and "The Nature, Methods, and General Objects of Meteorology." This last, by Robert H. Scott, F. R. S., Secretary to the Meteorological Council, is worth careful perusal by both scientists and the general reader.

fact that much of the contents of this volume first appeared in "Appletons' Journal" and "Harper's" and other magazines, does not detract from its value. It is a picturesque and thoroughly readable account of life and scenery in the region occupied by the Hudson's Bay Company, and
