and New York. The greatest depression of the barometer at the several sta- 
tions, where the minimum was within the limits of the term, took place at the 
hours following of December 21 (mean time at each station).

At Montreal and Quebec the rise of the barometer from its greatest de- 
pression was singularly steady and unbroken by any convulsive movements. 
At Quebec, indeed, this might be ascribed to the system of 4-hourly obser- 
vation pursued, but not so for Montreal, where the observations were hourly. 
At New Haven, New York, and Flushing also, the same remark applies with 
almost equal force; this places in a strong light the peculiarity of Albany, to 
which I have before alluded, viz. the broken and abrupt character of its 
curves; for in this instance its curve is most remarkably zigzaged over the 
whole of its upward slope. 
The following Table, exhibiting the movements of the barometer at Quebec 
and New York, before as well as during the storm, has been constructed by 
Mr. Birt from its records.

(H.) This storm was not felt at Bahama, the curve for which during this 
term exhibits a state of tranquillity, the diurnal phases only being observable 
and very well developed. ; 
(B.) Mr. Redfield remarks, that “ the period allotted for the observations 
includes, on this occasion, a portion of an extensive inland storm of marked 
character and rapid development ;” at nearly all the stations the latter portion 
only was observed ; the progressive character of the storm is very apparent 
from the curves. In consequence of the very extensive range of the barometer 
the scale is half of that which is employed for the other projections, namely 
75 of the larger divisions = °1.
