Continuation of Remarks on the Climate of Southampton. 
By John Drew, Ph.D., F.R.A.S. 
This communication was in continuation of a paper printed in full in the'Report 
of the British Association for 1851 and it likewise embraced general observations 
oo subjects connected with practical meteorology. The tables, which have been 
pihlisbed, contain the results of observations taken three times daily through the 
jw/s 1848, 1849, 1850. These now presented continue the series by observations 
Mde once a day, viz. at- 9 a.m., for 1851, 1852, 1853. The same care has been 
nun in observing, reducing, and recording, and the same instruments have been 
c -d throughout, except that for the last six months ot 1853, the observations of 
<>t. Cameron, R.E., recorded at the Ordnance Map Office, Southampton, have 
b«n substituted, his own barometer having been out of order. The author having 
k>aoil that the mean temperature derived from the 9 a.m., 3 p.m., and 9 p.m. ob- 
wnationa indiscriminately, agreed fairly, after the application of corrections for 
tody range with that deduced from

tadiscontinuedthe two later daily observations for the last three years, as mean results 
r rre a " dial he aimed at; and after having tested his results by various comparisons, 
, f”’® fu'ly persuaded that the mean state of the atmosphere, as regards pressure, 
t'npvrature, and moUture, has now been determined for Southampton with such an 
^'Proximate accuracy that for that end alone no further observations arc required. 1 he 
:“ b °r then proceeds to comment on each of the five tables. Table I. contains the mean 
^Asurea f l)r each month of the three years,—li e maximum with the date of its 
^urrvnce, the minimum with the date of its occurrence, and the monthly range 
q ’’ c P ara t ( -’ columns. Table II. gives the mean temperature for each month from the

i-inf' ° r °* e ra0n th and its date, and the monthly range. The author calls
