THE SCIENTIFIC PAPERS OF ASA GRAY. Vol I-REVIEWS OF WORKS ON BOTANY AND RELATED SUBJECTS, 1834-87. . The Athenæum says:-"We must be grateful, as indeed we have cause to be, for the rich legacy he has bequeathed to us. Prof. Sargent has made the selection, and he has done it so well that the present volumes may almost be taken as mirrors eflecting the history and progress of scientific botany for the last half century. It is, of course, impossible for us to do more can refer to these memoirs. Their number, their variety, and the space at our disposal alike preclude us from doing more than dicate their general nature and tendency. The first volume is occupied with Dr. Gray's reviews of several of the principal or sardard botanical works issued from 1836 to 1888, beginning with Lindley's Natural System of Botany,' and ending with Ball's Flora of the Peruvian Andes.' Some fifty of the more important publications are thus reviewed, and of these we can only say that Te wish there were more. The second volume comprises a series of essays constituting probably the most valuable part of the whole work, containing as they do the quintessence of the author's knowledge and opinions, and their application to the great roblems of plant-genealogy and geographical distribution. These are followed by a series of biographical sketches of naturalists im Augustine Pyrame de Candolle in 1841 to Louis Agassiz in 1886. These are mostly drawn up with rare skill and due proportion, so that the reader obtains, if not a complete, at least a just and, so far as it goes, an accurate insight into the character nd life-work of the individual. . . . Interesting as this period in the history of botany is already to those who are passing or have passed through it, it will become more and more so as science progresses, and the students of the future will feel themselves under even stronger obligations to Prof. Sargent than do those of the present.' The Saturday Review says :-"The first of these volumes embraces reviews of important botanical works, while the second contains a number of essays on botanical subjects, followed by biographical sketches of various scientific men. It will readily be understood that these latter writings are of peculiar interest, because the opinions of so independent and thoughtful a writer as Gray This contemporaries must always appeal to those who seek for information respecting the great names which mark the various eriods of scientific thought. If anyone is inclined to be curious or sceptical as to Gray's powers in this direction, let him read the graphical sketches of Robert Brown and of Humboldt, of Sir William Hooker and of George Bentham, and that of Charles Darwin.... But perhaps the most interesting of his articles to the general reader will be the essays on various botanical subjects the second volume... Some of these essays are extremely interesting, and all are pleasantly readable. . . . Here we must ave these delightful volumes, the publication of which reflects credit on all concerned, and which constitute a fitting memento of the greatest botanist America has produced."
