1. On the Nature and Character of European Winter Storms, 
with the best means of giving Warning of their Approach. 
By R. Russell, Esq. 
The object of this paper was to show the true character of storms, 
illustrated by those of 2d, 3d, and 4th December 1863. It was 
pointed out that the mode usually adopted of laying down the iso- 
barometric lines was calculated to present an erroneous view of their 
figure or form. The laying down representative lines in round 
numbers of 5 millemetres in each, or in two-tenths of an inch of 
barometric readings, lead deceptively to the conclusion that the 
areas of least pressure were circular or elliptical. 
It was then shown that the lines of equal pressures were ribbed 
into the latitudinal line of minimum barometer, which was usually
