THE work is published in quarterly numbers, of which two make 

 a volume containing at least 320 pages, illustrated by engravings, of 

 which, when very expensive, a past of the cost is paid by the au- 

 thors or contributors. Two volumes will be published the present year. 



This Journal, the only one devoted to American Science and 

 Arts, which has ever been attempted, has receiver] the general 

 approbation of the scientific public, both at home and abroad, and 

 has been adequately supported by original communications. Expe- 

 rience has evinced the necessity of requiring that the payments of in- 

 dividual subscribers should be in advance. 



To the friends of American Science, and to the friends of the 

 prosperity and reputation of this rising empire, the interests of the 

 American Journal of Science are respectfully commended. It 

 can never prove a lucrative work : and it remains for the public 

 to say whether it shall be sustained, so that those engaged in it may 

 not be losers, or whether it shall be relinquished, with the painful cer- 

 tainty that this vast republic will not support a solitary Journal, 

 devoted to its Science and its Arts. Its increasing patronage, and 

 the marked approbation with which it is received in Europe, afford 

 however, grounds to believe that it will be continued. |fc
