A NEW SERIES 



American Journal of Science and Arts, 



Will be commenced on the first of January, 1846, when the 

 present series of fifty volumes will be brought to a close. The 

 FIFTIETH VOLUME of the Old Series will consist of a 



GENERAL INDEX 



to the previous volumes, which will be published near the close 

 of the year 1845 or as soon after as it can be prepared. This 

 Index, the preparation of which has been often urged upon us by 

 our scientific friends, is quite essential to the full use of the entire 

 series of volumes, replete as they are with important papers, most 

 of them original American productions. It will contain the fullest 

 references to all the contents and authors of the 49 volumes 

 which it will cover. Every subject which is mentioned in the en 

 tire series, and every author whose opinions or writings are quoted, 

 will be mentioned, and those general principles of good arrange- 

 ment adopted, which will make it easy to find the word and subject 

 sought. 



It is hoped that every subscriber will be willing to pay for this 

 volume whether he possesses the entire work or not ; for the entire 

 series are to be found in so many public and even private libraries 

 that it cannot fail to be useful to every person having occasion to 

 refer to the records of science for the 27 preceding years. It is 

 only in this way that we can undertake the publication of a volume 

 so expensive to ourselves as this will necessarily be. It will be issu- 

 ed in two parts for greater convenience of transportation by mail, and 

 will be charged at the same price as the other volumes of the series, 



e. $3. 



In reference to the New Series, we will only say now, that there 

 will be several important changes in it from the present one, design- 

 ed to make it more valuable and important to all classes of readers. 

 The details of our plan as far as they need be made known will be 

 early announced. One principal motive for commencing this Series 

 is the hope of an increase of our present vej-y limited patronage. 



Many we trust will be willing to commence with the New Series 

 who have been deterred by the great extent of the present one — 

 not wishing either to purchase so large a number of back volumes, 

 nor to have a broken series in their library. We intend to continue 

 to furnish entire sets of the Old Series. 



We respectfully request our friends every where to use their best 

 exertions to obtain subscribers for the New Series.
