PROSPECTUS. 



In 1810, 11 and 12, the late Dr. Bruce, of New York, published 

 his Journal of Mineralogy and Geology in one volume of four num- 

 bers. 



The American Journal, was, however, the first, that in this coun- 

 try, embraced in its plan, the entire circle of the Physical Sciences, 

 and their applications to the arts. It was begun in July, 1818, and 

 has completed its twenty ninth volume. 



While it has prompted original American efforts, it has been sus- 

 tained by them, and being devoted to important national interests, in 

 a great measure common also to all mankind, it is, in that character, 

 known and accredited, both at home and abroad. It has elicited 

 many valuable researches and discoveries, and its miscellaneous de- 

 partment, in particular, has presented a great variety of topics, of gen- 

 eral interest. The Foreign Journals, (many of them sent in ex- 

 change,) often quote from its pages, which are in turn, enriched by 

 theirs; and it has thus, become identified with the science and arts of 

 the present day. 



Terms. — For four quarterly Nos., of not less than 200 pages each, 

 fully illustrated by plates, making, together, two annual volumes, of 

 at least 800 pages; six dollars — in advance. 



The quarterly ZiVerary journals, escape the heavy expense incurred 

 by this, for plates and for difficult technical composition ; and as they 

 enjoy, from obvious causes, a far more extended circulation, they 

 can be much better afforded at ^5 per ann. than this at ^6. With" 

 out a greatly increased patronage, this Journal could not be sustained 

 at jive dollars, as the actual receipts ivould not pay for the paper and 

 the mechanical labor. 



Postmasters are, occasionally, patrons of the Journal, when of 

 course their communications are franked. 



A number will be sent gratis, as a sample, when requested, especial- 

 ly to editors of newspapers who republish this appeal and prospectus, 

 and transmit the paper containing it to the editor. Names may be 

 lodged with any of the agents, or sent to the Editor or publishers,
