CONCLUSION. 



JLN the prospectus of this work, the expectation was expressed 

 that each Number would contain from 64 to 80 pages ; that as 

 many as four Numbers might be issued within the year, and 

 engravings were promised for such subjects as might require 

 them. 



The Numbers published, have actually contained from 104 

 to 132 pages, the four have been issued within a period often 

 months, and twelve copper-plate engravings and several wood- 

 cuts, illustrate the present volume. 



Of the subjects proposed in the plan of the work, our pages 

 contain notices, more or less extensive, of Geology, Mineralogy, 

 Botanj'^. Zoology, Chemistry, Natural Philosophy, Mathematics, 

 Useful Arts, Fine Arts, Inventions, Reviews, Biography, and 

 Intelligence. How far then we have redeemed our pledge, 

 we leave it for our readers to decide. 



In the commencement of an enterprise, for the first time 

 Attempted in this country, an enterprise arduous in its nature 

 and uncertain in its issue, it will not be doubted that consider- 

 able solicitude was experienced. 



To concentrate American efforts in science and the arts, by 

 furnishing a Journal to record their proceedings, will, in our 

 view, not only have a direct influence in promoting the honour 

 and prosperity of the nation as connected with its physical in- 

 terests, but will also tend in no small degree to nourish an 

 enlarged patriotism, by winning the public mind from the odi- 

 ous asperities of party. That entire success will attend our 

 efforts, it would perhaps be presumptuous to expect, but we 

 trust that the interesting previous question, whether such a 

 work can be adequately sustained, by appropriate materials, 

 may be considered as now decided. The support which we 

 have received, and for which we are deeply grateful, has been 

 far beyond our most sanguine hopes, and has caused us to dis- 

 pense with no small portion of those less important efforts of 

 our own, with which we were prepared to succour our infant 

 undertaking.
