This periodical was started (in 1872) to promote the diffusion of valuable
scientific knowledge, in a readable and attractive form among
all classes of the community, and has thus far met a

want supplied by no other magazine in
the United States.

Nine volumes have now appeared, which are filled with instructive and interesting articles and abstracts of articles, original, selected, translated, and illustrated, from the pens of the leading scientific men of different countries. Accounts of important scientific discoveries, the application* of science to the practical arts, and the latest views put forth concerning natural phenomena, have been given by sarants of the highest authority. Prominent attention has been also devoted to those various sciences which help to a better understanding of the nature of man, to the bearings of science upon the questions of society and government, to scientific education, and to the conflicts which spring from the progressive nature of scientific knowledge.

THE POPULAR SCIENCE MONTHLY has long since ceased to be an experiment. It has passed into a circulation far beyond the most sanguine hopes at first entertained, and the cordial and intelligent approval which it has everywhere met shows that its close and instructive discussions have been well appreciated by the reading portion of the American people. It has not been its policy to make boastful promises of great things to be done in the future, but rather to appeal to what it has already accomplished as giving it a claim upon popular patronage. But no pains will be spared to improve it, and make it still more worthy of liberal support, and still more a necessity to the cultivated classes of the country.

The following quotations illustrate the way it has been habitually spoken of by the press :

"That there is a place for Tax POPULAR SCIENCE MONTHLY, no one can doubt who has watched the steady increase of interest in scientific investigation manifested in this country, not only by a select class, but by the entire community."- New York Times.

"We think it is not too much to say that this is the best first number of any magazine ever published in America."- New York World.

"A journal which promises to be of eminent value to the cause of popular education in this country. New York Tribune.

"It is, beyond comparison, the best attempt at journalism of the kind ever made in this country." Home Journal.

"It is just what is wanted by the curious and progressive mind of this country, and ought to be widely circulated."- N. Y. Evening Pest.

"It is the first successful attempt in this country to popularize science in the pages of a monthly."N. Y. School Journal.

"THE MONTHLY has more than fulfilled all the promises which the publishers made in the prospectus of publication." Niagara Falls Gazelle.

"This new magazine, in our estimation, has more merit than the whole brood which havo preceded it." Oswego Press.

"In our opinion, the right idea has been happily hit in the plan of this new monthly." - Buffalo Courier.

The American Medical Journal, St. Louis, Mo.

A QUARTERLY JOURNAL OF ORNITHOLOGY.

ANNOUNCEMENT FOR 1877.

As the present number closes Volume I. of the Bulletin, the first number of Volume II. will appear in January, 1877, and the succeeding numbers of the volume will be issued on the first of each following Quarter. In closing Volume I. the Publishing Committee take pleasure in announcing that the publication of the Bulletin has met with encouraging success. Not only have contributions to its pages been received from the best ornithological talent of the country, but subscriptions have come in with reasonable frequency. Since, however, the continuance of the Bulletin is necessarily contingent upon the pecuniary support it receives from the public, we trust that our present patrons will not only all promptly renew their subscriptions, but will use their influence to extend its circulation. It is hoped that with the second volume it will be possible to increase the number of pages from twenty-four to thirty-two in each issue. In order to do this a considerable increase to our subscription list will be necessary, and we therefore appeal strongly to all friends of ornithology to aid in extending its circulation.

In order to assist in defraying the expenses of publication, advertising sheets will be issued with future numbers, relating mainly to Natural History, and especially to Ornithology. The attention of dealers in specimens of Natural History and collectors' and taxidermists' materials, and of publishers of works relating to Natural History, is hence called to the Bulletin as a desirable advertising medium.

The present Volume embraces one hundred pages of original matter, contributed largely by leading authorities on American Ornithology. The department of "General Notes" is particularly rich in notices of rare or little-known species, and the volume as a whole forms an important contribution to American Ornithology. As the magazine will continue under its present editorial management, Mr. J. A. Allen acting as Editor-in-Chief, and Professor S. F. Baird and Dr. Elliott Coues as Associate Editors, - and as it has the assurance of continued support from the best writers, the Publishing Committee do not hesitate to announce that Volume II. may be expected to be equally rich in important contributions. The Bulletin is intended to be national in its character, and for the present will be exclusively devoted to North American Ornithology. It being the only journal in this country devoted especially to ornithology, it is hoped that our appeal for pecuniary support will meet with a prompt response, and that we shall be able to enter upon the publication of Volume II. with feelings of confidence respecting the permanence of the Bulletin as an Ornithological Magazine.

Terms.Subscription, $1.00 a year (including postage), strictly in advance; single numbers, 30 cents. Subscriptions should be forwarded to Mr. H. B. Bailey, Newton, Mass.

Advertising Rates. First insertion, 30 cents a line (Bourgeois), or $12.00 per page; $6.50 per half-page. A discount of twenty-five per cent. will be made for each subsequent insertion.

Communications intended for publication, as well as advertisements, should be sent to Mr. J. A. Allen, Museum of Comparative Zoology, Cambridge, Mass.
