BY JOHN BARTHOLOMEW, F.R.G.S.
With General Index to 100,000 Places. The Times says :—"To those desirous of possessing an atlas of handy size, at a reasonable price, and amply supplied with naps executed with taste and accuracy, Mr. Bartholomew's Library Atlas ''may be commended. It is the first venture of the ind of any extent which the publishers, Messrs. Macmillan, have gone into, and it does them credit. The atlas is quarto in size, and therefore may be consulted with comparative ease. There are eighty-four sheets or plates, several containing a number of zaps. The physical and economical maps, and the very large number of maps devoted to the British Islands, are particularly relcome India, Canada, Australia, and the United States have several sheets given to them, while the rest of the world is presented in reasonable detail. There are few places one is likely to inquire for that will not be found in this atlas, which may be asily consulted by means of the copious index appended."
Scottish Geographical Magazine says :—“It is emphatically the atlas for newspaper readers and students of contemporary hanges in geography."
St. James's Gazette says :-" An atlas which in all essential points is one of the best of the kind that have ever appeared in lagland. ... We have no hesitation in recommending it.”.
The Pall Mall Gasette says :-“A perfect atlas de luxe is Mr. Bartholomew's ' Library Atlas of the World. The whole volume | dearly printed, largely designed, and stoutly bound ; also the very useful plan of printing titles and numbers on the back of the ups is adopted. Altogether this atlas is emphatically one that may be recommended.”
The Morning Post says :-““The Library Reference Atlas of the World' is a volume of noble proportions, and is certainly one f the best works of the kind extant."

With numerous Illustrations. Five Parts, Parts I., II., and IV. 218. each. Parts III. and V. 18. en Since this part-Vol. III., Part II.-of this work was published in 1884, our knowledge respecting this department of orat : chemistry has largely increased. The authors have endeavoured to represent the present position of the science by introducing d. results of all the latest and more important researches, with the effect that the greater part of the volume has been re-written. evidence of this they would refer, amongst others, to the researches of Curtius on the fatty diazo-compounds ; of Kiliani on constitution of the members of the sugar group; of Emil Fischer on the artificial production of certain members of this serio, Brown, Heron, and Morris, on the starches and dextrins; and, lastly, of W. H. Perkins, Jun., on the interesting gra. Polymethylene compounds. In the former edition, the derivatives of Furfuran, Pyrrol, and Thiophene, were also described in part; their number has, however, so largely increased that it has been found impossible to include them in the revised edition.

THE SCIENTIFIC PAPERS OF ASA GRAY.
Selected by CHARLES SPRAGUE SARGENT.
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 .. Prof. Sargent has made the selection, and he has done it so well that the present volumes may almost be taken 23 ST. reflecting the history and progress of scientific botany for the last half century. . : . It is, of course, impossible for us to do than refer to these memoirs. Their number, their variety, and the space at our disposal alike preclude us from doing more tha indicate their general nature and tendency. The first volume is occupied with Dr. Gray's reviews of several of the principe standard botanical works issued from 1836 to 1888, beginning with Lindley's 'Natural System of Botany.' and ending with Dr. * Flora of the Peruvian Andes.' Some fifty of the more important publications are thus reviewed, and of these we can only say is we wish there were more. The second volume comprises a series of essays constituting probably the most valuable part of whole work, containing as they do the quintessence of the author's knowledge and opinions, and their application to the re problems of plant-genealogy and geographical distribution. These are followed by a series of biographical sketches of naturale from Augustine Pyrame de Candolle in 1841 to Louis Agassiz in 1886. These are mostly drawn up with rate skill and 2 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 and life-work of the individual. . . . Interesting as this period in the history of botany is already to those who are pasir have passed through it, it will become more and more so as science progresses, and the students of the future will feel themser 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 seas contains a number of essays on botanical subjects, followed by biographical sketches of various scientific men. It will readily a understood that these latter writings are of peculiar interest, because the opinions of so independent and thoughtful a writer as Gm: on his contemporaries must always appeal to those who seek for information respecting the great names which mark the varim periods of scientific thought. If anyone is inclined to be curious or sceptical as to Gray's powers in this direction, let him read biographical sketches of Robert Brown and of Humboldt, of Sir William Hooker and of George Bentham, and that of Chemp Darwin. . . . But perhaps the most interesting of his articles to the general reader will be the essays on various botanical sabe: in the second volume. . : . Some of these essays are extremely interesting, and all are pleasantly readable. . . . Here we leave these delightful volumes, the publication of which reflects credit on all concerned, and which constitute a fitting memento greatest botanist America has produced.” DEVELOPMENT AND CHARACTER OF GOTHIC ARCHITECTL'RE. .

The Pall Mall Gazette says :—"This very interesting and ingenious book . . . is sure to attract attention everywhere. The ordinary reader will find it an agreeable and instructive hand-book, and the numerous woodcuts are well adapted to tbpurpose.”
