Observations on the weather at Royacottah on the 1 6th, at 10 a. m. 



Wind N.W. overcast, with Nimbi. Thick in N.E. ; lower stratum 

 of clouds moving rapidly with a N.E. current ; rain in N.E. and S. at 

 a great distance (forty miles), air very clear. Four p.m. overcast ; wind at 

 N. drizzling and heavy rain. At night, about two in the morning, wind 

 increasing to a gale, direction not certain, believed, S.E. ; 17th, at sun rise 

 wind quite fallen. 



At Bangalore, 



16th May. — 10 a. m. wind moderate, very cloudy and oppressive. At 

 day-light 5 a. m. Barometer 26*868, rain at night 17th ; 10 a. m. very 

 high wind, stormy ; it is to be noted, however, that in this month high 

 winds prevail at Bangalore. 



It will be remarked that the gale was felt simultaneously at Royacot- 

 tah and at Madras. 



Royacottah, 6th August, 1841. 



The Helen Mary, in company with the John William Dare, had nearly 

 the same weather, but her log affords no Lat. nor Long, from which to de- 

 duce her position. 



The Barque Champion also from Moulmein to Madras, in Lat. 10° 1' 

 N. to Lat. 9° 23' had tremendous gusts of wind from WNW. on the 16th, 

 veering to the SW. which seem to have been the usual monsoon ; but 

 as there is no longitude with her log it is quite useless as an authority. 



The Barque Ayrshire from Malacca to Madras has obliged us with a 

 capital log, but she was fortunately for her, though unfortunately for us, 

 in lat. 6° 30' N. and long. 89° 54' on the 15th. She had here a heavy 

 SW. monsoon, varying from SbW. to SW. 



The Bengal Merchant from Moulmein to Madras passed through Dun- 

 can's passage in the Andamans on the 15th with strong SEbS. breezes 

 and clear weather, which would agree with the centre of that day if we 

 suppose the storm to have extended so far, which I do not think it did. 



The Barque Catharine, about midnight on 15th had a shift of wind in a 

 gale from NE. to SW. and from that, to noon 16th, strong gales from 

 SW. being then in 8° 27' N. and 82° 32' E. Her vicinity to the high 

 land of Ceylon, and her being considerably to the Southward, with the 

 SW. monsoon blowing strongly, makes her's also a very uncertain datum,
