POSTAGE REDUCED. THE POSTAGE On the Eclectic will, hereafter, be about NINE CENTS, to any distance whatever, being a reduction of nearly one-half to all our subscribers over 100 miles. POST OFFICE LAW.-"On Magazines, 2 1-2 cents for the first ounce, and 1 cent for each successive ounce, not exceeding eight. Any thing over eight ounces is excluded from the mail." NOTA BENE.-After the 1st of July, our subscribers can remit to us, by paying their own postmaster, taking his receipt, and transmitting to us; which being presented to our postmaster here, entitles us to receive from him the amount receipted for. We are grateful to the Postmaster General for this accommodation, as it will enable us to receive our pay in a very convenient way. We hope subscribers, in arrears, will embrace this easy mode of making payment-no one can now be justified in withholding what is due. Postmasters can still frank notices of discontinuances; and we wish it understood that giving orders to a P. M. to return numbers is not a notice. We expect written or verbal information. LAW OF PERIODICALS. 1. Subscribers who do not give express notice to the contrary, are considered as wishing to continue their subscription. 2. If subscribers order the discontinuance of their periodicals, the publisher may continue to send them till all arrearages are paid, and subscribers are responsible for all the numbers sent. 3. If subscribers neglect or refuse to take their periodicals from the office to which they are directed, they are held responsible til they have settled their bills, and ordered them discontinued. 4. If subscribers remove to other places without informing the publishers, and their periodicals are sent to their former direction, they are held responsible. 5. The Courts have decided that refusing to take a newspaper or periodical from the office, or removing and leaving it uncalled for, until all arrearages are paid, is prima facie evidence of intentional fraud. TERMS.-Six Dollars a year; but if paid in ADVANCE, i. e., within the second month from the commencement of subscription, and at our own office, without expense to us, through private hands, or a post-master, FIVE Dollars will be received-otherwise Six, positively. GOOD NEWS.-Hereafter we shall uniformly wait for the arrival of the Steamers, and make up the entire Number with fresh matter. The selections from the Quarterlies must, of course, run on through two or three months; but all the rest of the matter will be from the latest arrivals, and the Magazine ready in ten days thereafter. So that we shall publish between the first and fifth of each month. In this way we shall have an advantage even over "Weeklies," in getting out fresh matter. Don't forget to read page 3 of cover, "SOMETHING NEW," and show it to your friends. Each subscriber can easily get some friend to take so good and cheap a work. Do it, and oblige us. EDITOR AND PUBLISHERS. THE SECOND SERIES OF THE AMERICAN JOURNAL OF SCIENCE AND ARTS, Will be commenced in January, 1846, TO BE CONDUCTED BY PROF. SILLIMAN, B. SILLIMAN, JR., AND AT NEW HAVEN, CONN. PROSPECTUS. The SECOND SERIES of this long established Journal, will be published in SIX NUMBERS annually, on the first of January, March, May, July, September, and November, respectively. The subscription price will be $5 per annum; and each number will contain from 140 to 150 pages. THREE NUMBERS will constitute a volume; and there will be (as in the old series) Two VOLUMES each year of nearly 450 pages each. The work will be fully illustrated by engravings as the subjects may require. Every effort will be made to render this New Series a faithful record of American and of Foreign science. With this view, particular attention will be bestowed on the miscellaneous department, especially in posting up the progress of the most important improvements and discoveries in Physical Science and the connected arts. In accomplishing this plan, the assistance of several gentlemen eminent in different departments of science has been secured. 1 2 The change in our plan is intended chiefly to accommodate authors with more frequent opportunities for publication, and the public with a fresher posting up both of European and American Science. We trust that the plan now proposed will be generally acceptable both to authors and readers. The increased expense of an enlarged and more frequent issue of the Journal in the projected New Series, and the reduction of price, will, it is confidently expected, be met by an enlarged subscription. The present sales being quite insufficient to authorize the change, efforts will be set on foot both in the large towns and in the country to extend the subscription; and we trust that our friends and present patrons will second the enterprise by a kindly influence. Liberal terms of discount are offered to those who are willing to act as agents in procuring new subscribers. Many, we trust, will be willing to commence with the Second Series, who have been deterred by the great extent of the First, not wishing either to purchase so large a number of back volumes, or to possess only a broken series. We intend to continue to furnish entire sets of the First Series, as we have done, from the beginning. With this view, we have, for a series of years, at an expense of several thousand dollars, reprinted many Nos. as they have run out. The sets occasionally sold do not remunerate us. The new Postage Law will materially aid the circulation of the Journal in distant places. The postage on a number of the Second Series will not be more than 10 cents, where it was formerly 35 to 40 cents. All communications respecting the Second Series should be addressed "To the Editors of the American Journal of Science, New Haven, Ct." The fiscal concerns of the Journal will be conducted in the name of the Senior Editor. The Second Series will be printed on New Type and handsome Paper. New Haven, Conn., November, 1845. PROSPECTUS OF A GENERAL INDEX VOLUME OF THE FIRST SERIES OF THE AMERICAN JOURNAL OF SCIENCE AND ARTS. The FIRST SERIES of the American Journal of Science will be closed with the FIFTIETH VOLUME, which will consist of a GENERAL INDEX to the previous volumes. This Index Volume will be published as soon as it can be prepared,-we trust it will appear early in 1846; and it may be forwarded to distant subscribers, either entire or in two parts, as may be most convenient. As it is not intended to interrupt the regular issue of scientific and practical communications, the Index will form an extra volume, concluding indeed the series of fifty volumes, but not occupying the time of any other volume. It will be directed to subscribers with one of the regular Numbers of the Second Series. The preparation of a General Index has been often urged upon us by our scientific friends, as it is quite essential to the full use of the entire series of volumes, (replete as they are with original American productions.) It will contain full references to all the 49 preceding volumes. Every subject and every author will be mentioned, and such general principles of good arrangement have been adopted, as will make it easy to find the word and topic sought. As this Index Volume will refer to many of the records of science and the arts during nearly twenty eight years of a very active period of investigation, it will possess, to a degree, a gene |
