already paid for computations, and about 701. for printing and 
other expenses, making a total of about 430/. out of the original 
grant of 5007. As this balance of 70/. will not be sufficient to 
complete the work, the Committee request that it may be ex- 
tended to 150/., which, they hope, will meet every expense. 
Tue Committee appointed to superintend the reduction of the 
stars in the Histoire Céleste, report— 
That about 33,000 stars have been already reduced, the cost 
of which has been 412/., exclusive of about 52/. for printing 
skeleton forms for the use of the computer. They further re- 
port, 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 
351. 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. Francis BAILy.

Second Report of a Committee of the British Association, con- 
sisting of Sir J. HERscue., Prof. WHEwE.L and Mr. Baty, 
for revising the nomenclature of the Stars, appointed at 
Newcastle, 1838. 
Tue revision of the northern hemisphere and the constellations 
visible in Europe has been continued by Mr. Baily, by carefully 
tracing the just and most authentic limits of the existing and 
recognised constellations, and by a careful examination of the 
several stars, in the course of which many singular instances of 
confusion and error in naming and placing have been detected. 
This process, which involves an investigation of the history of 
each star, and of the designations it has received from each of 
its observers, and in the several catalogues in which it occurs, 
is nearly complete, and may be considered as clearing the 
ground for a systematic nomenclature of the northern stars, as 
well as for an effective table of synonyms of each star. 
In the southern hemisphere, or rather in those constellations 
which are only visible to an observer in that hemisphere, Sir 
John Herschel has continued and nearly completed a chart of 
those stars only, and of all those stars which are distinctly visi- 
ble to the naked eye in a clear night, in which chart each star 
is represented of its true magnitude, according to a scale, in 
which the total interval from the stars of the first magnitude to 
the lowest inserted, in place of six degrees, is made to consist
