III. The course pursued by the storm, from its first appearance 
in the Mexican Gulf, appears to have been northeastward, chang- 
ing more and more eastward, till on crossing the Florida peninsula, 
its course was near E. N. E. ~ 
IV. The length of its observed track, estimated from Vera Cruz 
to a point in lon. 62°, is nearly two thousand and five hundred 
miles. If we consider ten days and a half as the time occupied 
in passing over this distance, it shows an average rate of pro- 
gress less than ten miles an hour. This will account for the 
extraordinary duration of this gale, which was not at any time 
remarkable for the extent of its area: and will account in like 
manner for the inequality of its observed duration, with the sev- 
eral vessels whose movements were different from each other in 
direction and velocity. In these respects, this gale contrasts very 
strongly with one which we have yet to consider, 
V. This storm deserves notice as pursuing a more easterly 
course in the lower latitudes than any other storm which has been 
traced in the American seas. It shows us, so far as is yet known, » 
the extreme southern route of those pom yas which have a 
northerly and easterly progression from the Gulf of Mexico or its 
orders. This peculiarity of the storm, viewed in connection 
with its previous course from the southwestern extremity of the 
Gulf of Mexico, has strong claims on our attention. 
VI. This gale is alike remarkable for the very southern position 
which must be assigned to the major axis, or apex, of its semi- 
orbital path ; if we Suppose that like other storms, it had a previ- 
ous westerly course, unreported, in still lower latitudes. 
VII. A sufficient cause for the above mentioned course of pro- 
8ression, or for the deviation froma more northern and usual 
course, is found in the relative states of atmospheric pressure at 
the time northward of the Gulf of Mexico and in the direction of 
Bermuda, respectively. \ 
. On the Mexican coast, this storm was properly known 
as a Norte or Norther, and like the usual storms or Northers of 
that region, it blew from northern points of the horizon, veering 
towards the northwest before its close. 
A Cotemporaneous Hurricane in the Atlantic. 
There was a very violent hurricane of short duration, narrow 
limits and more rapid progress, which passed a little northward
