Synopsis of a Meteorological Jowrnal. 157 
The results of the thermometrical observations are omitted, as be- 
ing of less general interest in an abstract of this kind. 
In dividing the horizon into four equal parts, in the foregoing ta- 
bles, the first or cardinal point in each quarter of the compass is n- 
cluded; N. being included in the N. E. quarter, E. in the S. E. 
quarter, &c. 
It is deserving of particular notice, that during some of the cold- 
est periods of winter in this occasionally severe climate, the predom- 
inating winds blow from the southwestern, or southern quarter of the 
horizon. This fact appears to be established by the annual reports 
which have been made to the Regents of the University, and, it is 
believed, will become obvious in proportion to the accuracy of our 
observations. It sufficiently demonstrates (without resorting to oth- 
er evidence) the fallacy of the notion commonly entertained, that 
winds are generally rectilinear in their progress and blow for the 
most part in right lines, over extensive portions of the earth’s sur- 
face ;—an error which appears to remain undisturbed in the minds 
of most meteorologists. 
OF THE BAROMETER. 
The results in the following barometrical table, has been obtained 
from a well adjusted Barometer, the position of which is supposed 
to be about ten feet above the mean level of New York harbor. 
Table of the mean height of the Barometer in inches, at five 
daily observations.
