MESSRS. LITTLE, BROWN, & CO. Have the pleasure of announcing to the public an entirely original work upon the BIRDS OF NORTH AMERICA, prepared by Prof. F. Baird, Assistant Secretary of the Smithsonian Institution, with the co-operation of Dr. Thomas M. Brewer and Mr. Robert Ridgway. The LAND BIRDS, complete in 3 vols, small 4to., illustrated by 593 woodcuts, and 64 plates of full life-size Illustrations of the Heads of the Species. Vols. I. II. LAND BIRDS now ready; Vol. III. ready in March. Price $10.00 per vol.; coloured by hand, $20.00. Vol. IV., on the Water Birds, is in an advanced state of preparation, and will, it is expected, be ready early in 1875. The authors have been permitted access to the unrivalled collections of the Smithsonian Institution, which embrace everything necessary to the preparation of a complete account of the birds of North America, in the immense number of skins, as also of nests and eggs, brought from every locality, and properly classified and arranged, and in most cases accompanied by detailed notices of their history. The object of the present work is to give a complete account of the birds of the whole of North America, north of Mexico, arranged according to the most approved system of modern classification; and with descriptions which, while embodying whatever is necessary to the proper definition of the species and their varieties, in as simple a language as possible, exclude all unnecessary technicalities and irrelevant matter. On this account it is especially recommended to the beginner. The descriptions are all prefaced by analytical and synoptical tables intended to diminish as much as possible the labour of identification, The illustrations consist: first, of a series of outlines exhibiting the peculiarities of the wing, tail, bill, and feet of each genus; but as these diagrams, however serviceable to the ornithologist, necessarily fail to give any idea of the form of the bird, they are supplemented by a second series, including a full-length figure of one species of each genus. In addition to the above, a series of plates is furnished, containing one or more figures of the head, in most cases of life-size, of every species of North American bird, including the different sexes, ages, and seasons, where these are necessary for the proper illustration of the subject. The Publishers feel justified in saying that the typographical execution of the work, and the accuracy and beauty of its illustrations, surpass anything of the kind ever published in America.

New Edition. 18mo, cloth, 45. 6d. By Professor HUXLEY, F.R.S. LL.D. "Pure gold throughout.”—Guardian. Unquestionably the clearest and most complete elementary treatise on this subject that we possess in any language."-Westminster Review. London: MACMILLAN & CO. "The first part of the work, presenting the reader with a continuous sketch of the history of the various inquiries into the physical constitution of the sun, cannot fail to be of interest to all who care for the revelations of modern science; and the interest will be enhanced by the excellence of the numerous illustrations by which it is accompanied."—Athenæum. "The book may be taken as an authentic exposition of the present state of science in connexion with the important subject of spectroscopic analysis. Even the unscientific public may derive much information from it." -Daily News. Second Edition, royal 8vo, cloth extra gilt, 315. 6d.

WYVILLE THOMSON, F.R.S., &c., Director of the Civilian Scientific Staff of the Challenger Expedition. Illustrated by 8 Maps and Plates and nearly 100 Woodcuts. "The book is full of interesting matter, and is written by a master of the art of popular exposition. It is excellently illustrated, both coloured maps and woodcuts possessing high merit. Those who have already become interested in the dredging operations will, of course, make a point of reading this work; those who wish to be pleasantly introduced to the subject, and rightly to appreciate the news which arrives from time to time from the Challenger, should not fail to seek instruction from Prof. Thomson."Athenæum, Second Edition, royal 8vo, cloth extra, 31s. 6d. The FORCES of NATURE: a Popular Introduction to the Study of Physical Phenomena. By AMEDEE GUILLEMIN. Translated from the French by Mrs. NORMAN LOCKYER, and Edited, with Additions and Notes, by J. NORMAN LOCKYER, F.R.S. Illustrated by 11 Coloured Plates and 455 Woodcuts. "Translator and editor have done justice to their trust. The text has all the force and flow of original writing, combining faithfulness to the author's meaning with purity and independence in regard to idiom; while the technical precision and accuracy pervading the work throughout speak of the watchful editorial supervision which has been given to every scientific detail. Altogether, the work may be said to have no parallel, either in point of fulness or attraction, as a popular manual of physical science."—Saturday Review. Third Edition, royal 8vo, cloth extra, 215. SPECTRUM ANALYSIS. By Professor ROSCOE, F.R.S. With Appendices, Engravings, Maps, and Chromolithographs. "The illustrations-no unimportant part of a book on such a subject-are marvels of wood-printing, and reflect the clearness which is the distinguishing merit of Mr. Roscoe's explanations."-Saturday Review. "The lectures themselves furnish a most admirable elementary treatise on the subject, whilst by the insertion in appendices to each lecture of extracts from the most important published memoirs, the author has rendered it equally valuable as a text-book for advanced students."-Westminster Review.

Diseases latent in the system throughout the winter will manifest themselves in damper and warmer weather, unless the blood be freed from impurities, and the body generally from noxious matters Holloway's Pills have long since established the highest reputation for the full and efficient manner in which they accomplished this purifying purpose. These excellent Pills search every organ, pervade every tis sue, and successfully grapple with all deleterious substances, either by neutralising them or expelling them. Holloway's medicine always promotes comfort, cheerfulness, health, and strength. The medicine is admirably adapted for the weak and delicate, whose frames are relaxed. whose nerves are unstrung, and whose digestions are upset by spring variations. |
