westerly wind which followed or closed up the easterly gale. 
This storm broke up the heavy ice in the Hudson for ten miles 
below Albany, and will long be remembered for the damages 
which it occasioned. It is not a little remarkable that the maxi- 
mum, minimum and extreme range of the barometer for a period 
of seven years, should all have occurred in this mouth. 
The fluctuations of the barometer and other phenomena which 
characterize our great storms, can only be thus cursorily alluded to 
inthis place ; but they have strong claims to the attention and 
inquiries of all observers; and when duly investigated, will prob- 
ably add more to our knowledge of the laws of storms and at- 
mospheric changes than all the mean results of instrumental 
observations which have been so industriously sought by philoso- 
phers and men of science. Of the available means for ascertain- 
ing these phenomena, few are more promising than the system of 
observation which is organized under the direction of the Regents 
of the University. It is now only necessary, that accurately ad- 
justed barometers be furnished for two or three selected stations 
in each of the senatorial districts, and that the observations of this 
instrument, for fixed hours, be returned to the Regents with the 
usual annual reports.
