Storms of the Atlantic Ocean. 
In a former paper, I have noticed some storms which could 
be traced across the Atlantic Ocean by means of the Paris 
Atlantic storms, I first provided myself with a large number 
of blank maps of the Atlantic Ocean, upon precisely the same 
: ffmeyer’s charts, so that observations could be read- 
Uy transferred from Hoffmeyer’s charts tomy own. I then 
wade a careful examination of all the charts in succession. 
For the first three months (December, 1878, to February, 1874), 
the isobars are not drawn beyond the meridian of 30° west o:

Mches), near the coast of the United States, and marked upon 
if € of my maps the position of the center of the lowest isobar.

of the lowest isobar for that date, and I did the same foreach 
lowing day as long as the low area could be identified. The
