OBITUARY.-J. NICKLES.-Through a letter from Mr. Achilles Delesse, dated Paris, April 7th, we have intelligence of the death of our correspondent, Mr. Nicklès, Professor in the University at Nancy. Prof. Nicklès died after a short illness, from a severe cold aggravated by breathing an atmosphere containing some hydrofluoric acid. He had been experimenting for some time upon certain fluorids.

WILLIAM MITCHELL, a well known mathematician and astronomer, died of general debility at the Vassar College, near Poughkeepsie, on the 2nd of April, aged seventy-six years. He lived in the Observatory with his daughter, Miss Maria Mitchell, the astronomer. William Mitchell was a member of the Society of Friends, and in all relations of life a most esteemed man.

V. MISCELLANEOUS BIBLIOGRAPHY.

1. Handy Book of Meteorology; by ALEXANDER BUCHAN, M.A., Secretary of the Scottish Meteorological Society. Second edition, 12mo, pp. 371. Edinburgh, 1868. (William Blackwood.)-This is, as its title declares, a very handy manual of meteorology, carefully prepared by a well known Scotch Meteorologist, and brought down to the times by a painstaking digest of the recent literature of the subject. It has been a prominent object with the author to present his subject in such a manner "as to engage on its behalf a wide spread interest in the general mind." The work is beautifully printed and illustrated by isobarometric and isothermal charts printed in colors in an extremely satisfactory manner. He has availed himself of the results of American investigators with fairness and good judgment for the most part. The work is on sale by Chas. Scribner & Co., 654 Broadway, New York.

2. Annual of Scientific Discovery, &c., for 1869. Edited by SAMUEL KNEELAND, A.M., M.D., &c. 12mo, pp. 377. Boston, 1869. (Gould & Lincoln.)-This old acquaintance is always an agreeable reminder of its predecessors of former years, as well as of numerous discoveries, facts and principles in various departments with which we are, as fellow laborers in the great field, more or less familiar, but which it is always pleasant to find marshalled in an orderly and compact manner, under their appropriate heads. Every such review of the year must of necessity be imperfect and unequal as an exposition of all that has been done, but even a cursory glance at Dr. Kneeland's Annual will show any fair-minded reader the vast variety of topics which now engage the attention of scientists and the painstaking care with which the editor has endeavored to present the most important results. The notes by the editor forming an introduction to the volume give an interesting summary of the progress of science for 1868.

A portrait (a better likeness than such efforts usually) of Prof. JAMES D. DANA is a pleasant frontispiece to the volume.

3. First Principles of Chemical Philosophy; by J. P. COOKE, Jr. Cambridge, 1868. 12mo.-This important manual of instruction can hardly be said to be published in the ordinary sense of that term. It has been prepared especially to present the philosophy of chemistry in such a form that it can be made with profit the subject of college recitations, and to furnish the teacher with the means of testing the student's faithfulness and ability. To Prof. Cooke more than to any American, is due the credit of having made chemistry an exact and disciplinary study in our colleges. The present work has grown out of his "Problems," prepared several years since to elucidate his methods, and is designed to inculcate these methods by the use of the unitary system of chemical notation and philosophy. It is a logical analysis and deduction of the subject which will command the careful attention of chemists whose duties require them to instruct in this difficult department. 4. Outlines of Physiology, Human and Comparative; by JOHN MARSHALL, F.R.S., with additions by the American Editor, F. G. Smith, M.D. 1042 pages. 8vo. Philadelphia. (Henry C. Lea.) 1868. This work treats of physiology as connected with anatomy, chemistry and physics, on which its principles so largely depend. It brings the reader to the level of the most recent investigations. It is a work of vast labor evincing, in many respects, the utmost ability and research. So far as the subject matter of the work is concerned this book is probably unsurpassed, and perhaps not equalled by any treatise on physiology in the English language.

This is more than we can say for the artistic and mechanical execution of the work. It is surprising that with a text of such excellence the publishers contented themselves with a series of illustrations inferior to those in some other works of much less merit. It is to be hoped that in the next edition they will give attention to arranging the material in conspicuous paragraphs with appropriate headings, and also introduce illustrations in keeping with the style of modern art, and more recent investigations.

5. The Ornithological Collection of John Cassin.-It will be seen by the advertisement that the very valuable collection of birds belonging to the late lamented ornithologist, John Cassin, is now offered for sale. This collection includes the types of many new species described by him, as well as numerous very rare and beautiful forms, seldom offered for sale, and would be a very important addition to any museum. We learn through Dr. George Smith that Mr. Cassin's birth-place was incorrectly given in our last number. He was born in Upper Providence township, Delaware county, Pa., September 6th, 1813.

6. Catalogue of the Orthoptera of North America, described previous to 1867; by S. H. SCUDDER. Smithsonian Miscellaneous Collections, 1868.-This work, although intended only as a compilation, cannot fail to be of great value to working entomologists. Every name under which species have been described is entered, with full references to the works in which it occurs and the locality from which it was stated to have come, but no attempt has been made to give the actual synonymy. It is accompanied by a

full list of authorities, and at the end is a tabular arrangement of the genera and families, which appears to us more natural than the systems usually adopted.

7. Memoirs of the Peabody Academy of Science, Vol. I, No. 1, royal 8vo. Press of the Essex Institute, Salem, Mass.-This new serial makes its appearance in a style that will compare favorably with the publications of any other scientific institution, whether foreign or American. The typography is beautiful and the paper of excellent quality. The size is well adapted for the purpose. The part now issued contains a very complete monographic revision of the Large, Stylated, Fossorial Crickets, by S. H. Scudder, illustrated by an excellent plate, giving details of the wings and fore legs of most of the species. This group, including the species usually designated as Mole-Crickets, the author divides into two genera, Gryllotalpa and Scapteriscus. The latter includes eight species, of which four are new; the former fifteen species, two of which are new. Nearly all the known species have been carefully redescribed, with full tables of measurements and localities.

8. Bulletin of the Essex Institute, Vol. I, Nos. 1 and 2. Salem, Mass. 8vo. Jan. and Feb., 1869.-This new monthly serial is intended to replace, in part, the "Proceedings of the Essex Institute," which will be discontinued at the end of Vol. VI. It will contain the reports of the meetings of the Society, lists of donations to the museum and library, etc., together with the shorter and less technical communications, in both the historical and scientific departments. It is furnished at the very low price of one dollar per annum.
