afternoon of the 22d.* From these data it would appear that this 

 storm was of large extent, and that its centre of rotation passed 

 on a line which lays to the seaward of the city of New-York. 



As the series of barometrical observations above suggested, are 

 not likely to be comprised in the reports of the several academies 

 to the Regents for the current year, it is hoped that this deficiency 

 will be supplied, in part, by voluntary reports from gentlemen in 

 different parts of the State. Reports of like character, and also of 

 winds, from some points in the Canadas, and in the western States, 

 are also deemed a desideratum, and would, doubtless be thankful- 

 ly acknowledged by the Institute. 



J^ew-York, February 25y 1837. 



Abstract of a register of the barometer and hygrometer kept in the 

 city of Albany during the year 1836, by Matthew Henry Webster, 

 Corresponding Secretary of the Albany Institute. 



A desire to contribute in some small degree to a knowledge of 

 the atmospherical phenomena, exhibited in our city, induced me to 

 commence with the past year a register of the barometer, ther- 

 mometer, &c. which was continued with considerable regularity. 

 The situation, however, in which I was obliged to expose my in- 

 struments, was so much affected by radiation from neighboring 

 walls, which at the same time afforded an almost perfect shelter 

 from northerly winds, as to render the results given by the exter- 

 nal thermometer of little value: they have therefore been left out 

 of this statement. But as these circumstances do not affect the 

 dew point, the monthly mean of the morning and evening, and of 

 both observations, the maxima, minima, range, and the degree of 

 moisture on the hygrometric scale, in which 1,000 represents the 

 term of saturation, are given in the following table.
