174 Miscellanies. 
I cannot conclude without expressing my deep sense of obligation 
to various scientific gentlemen, who have been so good as to commu- 
nicate to me their observations. I am particularly indebted for many 
valuable suggestions, to Gen. DeWitt of Albany, and to Alexander C. 
Twining, Esq., of West Point. Indeed, on comparing notes with 
Mr. Twining, I learn, that we have pursued nearly the same track of 
investigation, and arrived at some results very similar to each other ; 
and [ am happy to share with so able a coadjutor, the responsibility 
of bringing them before the public. 
MISCELLANIES. 
FOREIGN. AND DOMESTIC. 
British and American Journals, of Science.—The diminution of 
the number of periodical works devoted exclusively to science in 
Great Britain, has, within a few years, been quite remarkable. One 
highly respectable quarterly journal, published in London, at the 
fountain head of science, has ceased to exist. ‘Two of the monthly 
journals of the metropolis, which, during several years, maintained a 
friendly rivalship, at length coalesced, and they have since been join- 
ed by an Edinburgh quarterly journal, forming a monthly trio in uno, 
not larger than either of the original journals. The only quarterly 
at present in Great Britain, is Prof. Jameson’s Edinburgh New 
Philosophical Journal, which has attained its twenty eighth or thirtieth 
number. This is a work of about the same number of pages as the 
American Journal. Many of the changes alluded to, have taken place 
since the commencement of our labors, and it cannot but be gratify- 
ing to us, to find so many of the pages of our Journal transferred to 
those of the only remaining quarterly, which promulgates science 
among British readers. The last two numbers which have come to 
hand, contain each twenty pages taken from one Vol. (23d) of our 
Journal. These extracts are not confined to original articles, but 
extend largely to the matter selected by us from the continental jour- 
nals, and newly translated for our pages. While we are pleased with 
this tribute to the taste and judgment of our selections and transla- 
tions, it may perhaps be no more than right to say, that when such 
materials are copied from one journal to another, the source from 
which they are derived, ought, we think, to be acknowledged.
