about 10,000 ;—the sum of £105 remaining of the original grant 
unappropriated ; which the committee recommend to be applied, 
(with such additional grant as may be needed,) to the printing 
and publication of the catalogue, without which it is evident that 
little or no benefit can result to astronomical science from the 
work so accomplished. With the catalogue, and forming an in- 
troduction: to it, an account of the process pursued in the redue- 
tions, the constants used, and all other matter needful for a com- 
plete understanding. of the work, ought also to be printed; and 
should it be the pleasure of the Association to order the publica- 
tion, will be furnished by Mr. Henderson. The estimated cost 
of the publication so recommended, may be roughly stated at 
about £250, for printing, paper, &c. of 500 copies of the cata- 
logue and introduction.—J. F. W. Herscueu.”’ 
The President observed, that the discussion and publication of 
these observations upon the stars of the southern hemisphere, 
originally made by M. de Lacaille, now possessed an increased 
interest in consequence of the recent observations of Sir John 
Herschel, prosecuted at precisely the same locality, thus furnish- 
ing two series of observations upon the same stars at epochs sep- 
arated by a very considerable interval of time. 
' Mr. W. Snow Harris reported on the Meteorological Obeoreai 
tions made at Plymouth last year. He stated that at the close of 
1842, he should be able to revise (and bring to the next meeting 
of the Association) the results of the series of meteorological ob- 
servations continued hourly, night and day, without material in- 
terruption, during ten years. He now submitted only a general 
discussion of five years’ observation of the barometer during the 
years 1837 to 1841, both inclusive, and some observations and 
experiments on the wind, made with Prof. Whewell’s anemome- 
ter. ‘The observations were made at a height of 75 feet above 
the level of the sea, and were reduced to 32° Fahr. He exhib- 
ited a chart, showing the lines resulting from the means in each 
of these years, and also the mean of the whole five years, and 
noticed the surprising coincidence in the general character of all 
these lines, and the very few and small deviations they present- 
eda. remarkable result, considering the frequent atmospheric 
to which these latitudes are liable. The mean pres- 
sure of the six years corresponded = that already obtained:
