The Editors must, however, be allowed earnestly to 

 call upon all those to whom the success of such a Work 

 may seem important, for their exertions to extend its 

 sale, which though just sufficient to ensure permanence, 

 and gradually on the increase, is still far short of that 

 which its well-wishers might hope for. It can hardly 

 be necessary for the Editors to state that their means of 

 giving additional interest and value to these Annals, in 

 various respects, must necessarily depend upon their 

 having a greater sale than will merely cover the expenses 

 of Publication. 



P.S. It is hardly possible to speak of the difficulties with which 

 Scientific Journals have to struggle in this country in comparison 

 with all others, without adverting to the very heavy expense of Post- 

 age, and expressing our regret and mortification that nothing has 

 yet been done by Government to relieve Science and Literature 

 among us from a burthen so enormously oppressive.
