pressure, especially on February 22nd, it would not have 
reached above 40lbs. on the square foot. But it is reported 
that during the storm of February 22nd, a pressure was 
at Liverpool of more than 70lbs. on the square foot; and on 
December 27th, 801bs. on the square foot was recorded. 
I confess it is with difficulty that I receive such a report. 
Probably the height at which the Liverpool instrument is 
placed may give some value to the record. 
Whilst I was arranging with Mr. W. Oxley for an instru- 
ment that would record higher pressures, I met with a 
description of an anemometer in the Proceedings of the 
Meteorological Society, vol. 4, page 161. My first objection 
was to the following statement respecting the pressure of 
the wind in this country : “ The greatest pressure here 
provided for is 201bs. on the square foot, which is sufficient 
for the winds that occur in this country, as proved by 
careful experiment.” Certainly such a statement is very 
far at variance with the records that are said to have been 
made at Liverpool, or even at Greenwich. However, I and 
Mr. Oxley gave the instrument a careful consideration, and 
at length abandoned it as a means of recording such high 
pressures as we were sure had been recorded. Besides this, 
its mode of recording the directions whence the high 
pressures come is far too complicated and confusing. I at 
length suggested that Mr. Oxley’s own anemometer could 
be made to accomplish all that this instrument professes to 
do, and in a much more effectual manner. But no sooner 
were my ideas thrown out, than my friend’s mechanical 
skill accomplished what was wanted in the simple manner 
in which it now exists. 
This instrument does not profess to record the time when 
the pressures occur, though an arrangement could easily be 
adapted for this purpose. In this respect alone is it inferior 
to Osier’s anemometer. But as every observer of the wind 
is furnished with Mr. Robinsons anemometer, the hourly
