the degree that would have taken place had the thermometer, 
barometer, and hygrometer, remained the same as in the 
NE. monsoon ; but having been different, the velocity was 
accelerated from both guns on this account, in like manner 
as it was retarded in the NE. monsoon. 
The following are the results deduced from the experi- 
ments in the different tables. I shall first give the general 
results from Table I. and VI.

Here we find a difference from the former general result 
by the observations with the Mount gun ; the reason of 
which appears to be, that I could not, as I have before stated, 
carry on the observations during at least a complete revolu- 
tion of the changes in the atmosphere ; and that this is the 
reason I shall now endeavour to show. The interval wanting 
is between the 28th of March and the 16th of July. Had 
this interval been wanting in the experiments with the Mount 
gun, there would have been a difference of 0,237 seconds in 
the mean result ; for the mean of the experiments in this
