PROSPECTUS. 



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

 ihe first and only volume of his Journal of Mineralogy and Geology. 

 The American Journal was begun in July, 1818, and has completed 

 its twenty fourth volume ; it was the first, that in this country, em- 

 l)raced in its plan, the circle of the Physical Sciences, and of their 

 .applications to the arts. 



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

 tained by it, and being devoted to important national and human in- 

 terests, it is, in that character, known and accredited, both at home 

 and abroad. It has elicited many valuable researches and discover- 

 ies, and its miscellaneous department has presented a great variety 

 of topics, of general interest. The Foreign Journals, (many of them 

 sent in exchange,) often quote from its pages, which are in turn, en- 

 riched by theirs ; and it has thus become identified with the progress 

 of 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 literary journals, escape the heavy expense incurred 

 by this, for plates, and enjoying, from obvious causes, a more extend- 

 •ed circulation, can be much better afforded at ^5 per ann. than this 

 at ^6. With its present patronage, this Journal could not be sustain- 

 ed at five dollars, as the actual receipts would not pay for the paper 

 and the mechanical labor, 



Complete sets, at a proper discount, are furnished, to order, in Nos. 

 or bound. Postage is to be paid on all orders and remittances, but 

 (not on communications. 



When payment is desired for communications, it must be specified 

 ,to the editor, or it will be taken for granted that they are gratuitous. 



A number is sent gratis, as a sample, when requested, and additional 

 subscriptions are now respectfully solicited. Names may be lodged 

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

 work may be obtained through all booksellers. 



A satisfactory compensation will be allowed to all persons who ob- 

 tain good subscribers; and agents and booksellers can, if they choose, 

 j-etain upon their own books, the names which they may procure ; due 

 jfloticfi being given to the Editor.
