15. New Scientific Journals. 
1. The Microscopic Journal, edited by Daniel Cooper, Esq. Lon- 
don: J. Van Voorst.—This Journal came into existence about the same 
time as the Microscopical Society, and it is, as has been stated in 
our notice of that society, its authorized organ of communicating the 
proceedings and abstracts of its papers to the scientific world. It 
also contains many original and valuable articles from other sources. 
It is published monthly, and nineteen numbers have already ap- 
peared. 
2. The Geologist. By Cuartrs Moxon, Esq. H. Bailliére, pub- 
lisher, 219 Regent St. London. (Monthly.)—We have not seen this 
journal ; but suppose it to be, as its name implies, wholly devoted to 
geology. It was commenced on the Ist of January, 
3. The Chemist, or Reporter of chemical discoveries, be. By Cuas. 
Warr and J. Warr, Jr. London: R. Hastings, 18 Cacey St.—This 
journal is also monthly, and has been in existence about two years; 
the second volume is completed. Not having examined the work, 
we cannot speak of its value. 
4. Under the same head, we may properly notice a change which 
has recently been effected in the editorship of our esteemed contempo- 
rary and fellow laborer in the general cause, The Journal of the Frank- 
lin Institute ; whereby the American Repertory of Arts, formerly con- 
ducted by Prof. Mapes, in New York, has been transferred, with its 
editor and subscription list, to the Institute Journal, thus combining the 
talent of the two works. This change must be attended with valuable 
results to the energy of the old work, and raise its already high repu- 
tation. The two hundred and first number of this work is ed 
published. 
5. The Cambridge Miscellany of Mathematics, Physics, and Astron- 
omy. Quarterly. Edited by B. Perrce, A. M., Prof. of Math. and Nat. 
Phil. in Harvard University. Boston. Nos. 1 and 2.—This journal is 
devoted principally to the solution of mathematical questions, proposed 
by the editor or his correspondents. It has, however, a chapter 
devoted to general physical science, in which interesting papers have 
been published by Prof. Lovering, the Editor, and other contributors. 
Each number contains forty eight pages,—it was commenced in April 
of the present year. 
6. Memoirs and Proceedings of the Chemical Society. Parts 1 and 2.
