LIEUT.-COLONEL SYKES’S DISCUSSION OF METEOROLOGICAL 
blow Haifa point to the westward of W.S.W., at Calcutta blows chiefly from the S., 
and the prevailing N.W. wind of Bombay becomes a northerly wind in Calcutta. 
The Table shows that almost the only hours of calm are at sunrise and at sunset. 
IVinds at Mahahuleshwur. 
At Mahabuleshwui’j at 4500 feet above the sea-level, the following is the mean 
monthly direction of the wind, as given by Dr. Murray in a synoptical view of fifteen 
years’ observations ; —

From the generalities in the Table, it would not be safe to deduce any normal con- 
ditions from comparisons with the wind tables of Madras, Calcutta or Bombay. In 
the months of January, November and December, Mahabuleshwur would appear to 
share more largely in the easterly winds of Madras than in the N.W. winds of Bombay 
in those months ; but in February, March, April and May, and the rest of the year, 
the station would appear to have much the same winds as prevail at Bombay. Its 
elevated position, therefore, does not remove it from the periodic currents of air of a 
lower level. Even Dodabetta, at its great elevation of 8640 feet, is partly subject to 
the periodic winds of Madras and Bombay, at least as far as one year’s record of 
observations recorded hourly from Osler’s anemometer enables us to judge.
