1843, Nov. 26, lat. 9° 40’ N. Dark and threatening—strong, heavy squalls, 
Nov. 27, “ 7 4 N. Sudden and dangerous gusts and violent squalls. 
Nov. 28, “ 4 27 N. Heavy rain and most terrific squalls. 
Noy. 29, ‘* 1 20 N. Succession of dangerous squalls. 
Nov. 30, “ 1 18. Dismal weather and violent squalls. 
Dec. 1, “ 3 15 8S. Dark, gloomy weather and violent squalls. 
The following is from the log-book of the Fyzul Curreem, 
for the same period : 
1843, Nov. 27, lat.5° 117 N. Heavy squalls, N.N.W. 
Nov. 28, ‘“ 2 6 N. Fresh gale, west. 
Noy. 29, “ 0 54 S. Gale from west, increasing steadily to midnight. 
Noy. 30, “ 3 50 S. . Steady at west. 
ec. 1, “ 5 39.8. Strong sea from W.S.W. 
Dec. 2, ‘“ 6 41 8. Heavy head sea. 
The courses of these storms while moving westward, range 
from 13 degrees south of west to 86 degrees north of west. In 
two cases the course was reported to be south of west, and in 
one case it was exactly west, which result accords very closely 
with that before found for West India hurricanes. The ave 
rage velocity of progress of these storms while advancing west: 
ward was 8°1 English statute miles per hour, which is less than 
half the average velocity of West India hurricanes. 
e average latitude of the storm-centers when the course 
became due north was 19°8, and the latitudes range from 1g 
to 24°°3, which is ten degrees more southerly than the latitude 
before found for the West India hurricanes. The average 
velocity of progress of these storms when advancing northward 
was 9°38 miles per hour. 
he average course of these storms after turning eastward, 
was 35° east of north, and their velocity of progress was 9° 
miles, which is scarcely half of the velocity found for West 
India hurricanes. 
Column 10th shows that rain accompanied every one of 
terms were no exaggeration. The following table shows the 
amount of rain-fall in twenty-four hours at certain stations:
