date, a storm of much rain and wiud of considerable violence 

 occurred, but no observation was made till 7 a., m. at which hour the 

 wind was at E., the atmosphere dark and hazy in every direction, 

 clouds, cirri and cirro strati, pointing in no definite direction. The 

 wind continued at E. till 2 p. m. when the storm passed over, and 

 could be distinctly seen proceeding direct N. and occupying about 

 § the circumference of the horizon. 

 It would appear that in this storm 



a. The circular motion of the wind was from L. to It. or with 

 the hands of a watch. 



b. That in all probability the storm formed over the station, and 

 did not acquire its progressive motion northward until towards 

 2 p. M. shortly before it passed away in that direction. 



c. That this was also one of the cold weather falls of rain, com- 

 mon in upper India. 



4. — Mth Feb. 1853. During the morning the sky presented a 

 confused appearance, (I know no better expression to make use of.) 

 It was almost entirely overspread by strati and cirri variously modi- 

 fied. Towards IN". W. — N". and N. E. ; the streaks of these clouds 

 were irregularly blended and curved, — the curves being ia no defi- 

 nite direction. 



Shortly after mid-day the wind, which had been blowing moder- 

 ately from 1ST. E., increased much in violence, — carrying with it 

 clouds of dust. It was unattended by thunder or lightning. It thus 

 continued with temporary variations in intensity till aboub 5, 30 p. m. 



During this time the direction of the wind did not vary, nor did 

 any rain fall until about 5 p. M. and then, only a few drops. In the 

 evening a dark cloud was observed at a great distance resting on 

 the horizon E. and N. E. 



It would appear that in this slight storm 



a. There was no circular motion of the wind. 



5. — 7th March, 1853. The sky during the previous day was 

 cloudy and threatening. Towards sunset a dense mass of black 

 cloud arose from the horizon and gradually extended over the sky. 

 About 7 p. m. of that day the whole of the firmament was hidden by 

 a veil of cloud ; the horizon only being observed clear and bespangled 

 with stars. Lightning was observed S. W. and W. with thunder
