plated ; and even in the Rey limited range afforded by the speci- 
mens now presented, affords ground for interesting remark. ‘Thus 
we see that the march of the barometer in the only two Irish sta- 
tions which have furnished observations, (Markree and Limerick, ) 
while agreeing well with each other, differs most decidedly from 
its corresponding march in all the English stations ; which, 
the other hand, offer a good correspondence, inter se. * * It 
would be premature, at present, to enter fully into the details of 
the further steps contemplated in these reductions, as they will 
be, of necessity, materially influenced by the aspect under which 
the subject shall present itself in its progress, and especially by 
the discussion of one or two of the most complete series, among 
which, thanks to American zeal and industry, the group including 
the United States promises to be the most prominent. Only a 
very trifling sum (under £2,) has been hitherto expended (for 
the printing of the skeleton forms,) out of the original grant of 
£100; but the continuance of the grant will be required to meet 
the further requisite expenses. It is only justice to Mr. Birt to 
observe, that his part of the work appears to be executed with 
great care and judgment.—Signed, J. F. W. Herscuet. 
Reduction of the stars in Lalande’s Histoire Céleste.—The 
Committee appointed to superintend the reduction of stars in the 
Histoire Céleste, report, that about 33,000 stars have been already 
reduced, the cost of which has been about £412, exclusive of 
about £52 for printing skeleton forms for the use of the com- 
puter. They further report, that there are about 16,000 more 
stars to be reduced, the cost of which will be about £200 more. 
As the original grant will not cover the whole of this expense, 
(there being only about £35 remaining out of that grant,) the 
Committee suggest the propriety of extending the grant for the 
ensuing year to the £200 above mentioned, which, they trust, 
will complete the work. Aug. 25, 1840.—Francts Batvy. 
Catalogue of Stars of Roy. Ast. Soc.—The Committee ap- 
pointed to superintend the extension of the Royal Astronomical . 
Society’s Catalogue of Stars, report, that the work is in consid- 
erable progress, and that it will probably be completed before the 
next meeting of the British Association, in 1841. They further 
report, that £360 have been already paid for computations, @ 
about £70 for printing and other expenses, making a tol 
about £430, out of the original grant for £500. As this bala
