GENERAL REPORT ON THE RESIDENCY OE SINGAPORE.- 6$S 
variation we find in the general laws of nature, though how often 
do we remark, how changeable is the weather! From these 
observations carried on nearly five years, the wind blows from the 
north east during 474 days 9 hours, from the opposite direction 8. 
W. during the contrary monsoon 470 days 13 hours, another 
deduction is made that during the months of December, January, 
February and March the wind blows more continuously from the 
north east, than any other direction, while in the months of June, 
July, August and September the wind is principally to the south 
west. During November the prevailing wind is north west while 
its antagonist south east blows in the month of June. Another 
fact is elicited,—viz that in April we have the winds blowing 
from the direction of N. W. and N. E. 1852 hours and from the 
S. W. and S. E. 1868 hours. In October we have them blowing 
from the N. W. and N. E. 1567 hours and from the 8. W. and 
S. E. 1395 hours, thus the wind in changing from the N. E. 
monsoon to the south west seems to do so gradually from N. E. 
to N. N. E. then N. W. to West, then 8. W. and in changing from 
the south west to the north east retraces its progress by retaining 
its westerly direction and not reaching the N. E. by south, then 
S. E. and East but adopting the same direction by which it reached 
the S. W. from N. E., viz : a Westerly. 
In the same paper the following facts are announced with regard 
to the fall of rain and quantity of moisture in the atmosphere. 
In 1820 rain fell on 229 days, in 1821 on 203, in 1824 on 136 
and in 1825 on 171 days giving an average on 4 years of 185 
rainy days and 180 dry in a year. The quantity of rain that falls 
is well illustrated in the following table:—
