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

 tained by them, and being devoted to important parional 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 Zzterory 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 $b per ann. than this at ^6. With 

 its present patronage, this Jovrnal could not he sustained, at five dol- 

 lars, as the actual receipts would not pay for the paper and the me- 

 chanical labor. 



Postage is to he paid on all orders and remittances, hut not on com- 

 munications. Postmasters are, occasionally, patrons of the Journal^ 

 when of course their communications are franked. 



A number is sent gratis, as a sample, when requested. Names 

 may be lodged with any of the agents, or sent to the Editor or pub- 

 lishers, and the work may be obtained through all booksellers, or 

 from the Editor. 



Jl compensation of one third ivill be alloived to all persons obtain- 

 ing subscribers, who pay the first year's subscription in advance ; 

 and agents and booksellers can, if they choose, retain upon their own 

 books, the names which they may procure; due notice being given 

 to the Editor. 



Complete sets are furnished to individuals, and to the trade, at a 

 suitable discount. 



The Editor will draw on his agents semi-annually, (that is, on the 

 publication of No. 2, of each volume,) in all cases where payment is 

 not otherwise provided for ; the drafts will be usually payable April 1, 

 and Oct. 1. A semi-annual or an annual payment in advance is, in 

 all cases, expected from the individual subscribers, and the bills are 

 forwarded accordingly with the Journal. 



For single subscribers, the mail is, decidedly, the best mode of con- 

 veyance: the postage is about that of a twice weekly neivspaper, that 

 is, from |!.10 to fl.32 per annum.
