Summary of Depressions. 

 6, greatest, (all below 29'200.) 



Remarks. 

 In one instance only, 3 days between 



time of dep. and max. decl. 

 Both within 10° of equator. 

 Of which, in six instances, the time 



2, lesser,. . (between 29'200 and 29-220.) 

 10, least, ..(between 29-220 and 29-300.) 

 between maximum declination and depression is not more than two days ; in 

 one instance, three days ; in one instance, moon's declination was less than 

 10°; two instances, irregular; one, 12' more than 10° from the equator; one 

 (-291), of four days' distance between time of depression and maximum declina- 

 tion. I must now end this paper, begging permission to resume the subject, as 

 I may find opportunity to do so.

It may not be deemed out of place to notice here the amount of wind and rain, 

 which accompanied each depression. In five cases out of the six, a depth of rain 

 of from 6£ to 9 inches was deposited within three days of the depression. In 

 1823, no notice is taken of the wind in the Register, but the Kedgeree report 

 6tates, " light airs" on August 15th, (the day of the depression,) and " hard 

 gales from southward and eastward" on the (16th), the day after. The Gazette 

 laments inundations in the upper parts of Bengal, loss of life, villages swept 

 away, and devastation of the crops. In June, 1829, the Register notes on the 

 day of depression " violent wind all night, with thunder and lightning." In 

 May, 1830, and May, 1833, were violent storms or hurricanes, the effects of 

 which must be yet remembered by most of us. In August, 1834, was a heavy 

 gale of wind. In July, 1829, alone, neither the quantity of wind nor of rain 

 appears to have been great. The former is not noticed, the latter was less than 

 1*75 inches. We may remark too, that in the first instance alone, viz. that of 

 August 15th, 1823, was the declination of the moon south. The rest have all 

 occurred between the 20th May and 4th August, or from 31 days before the 

 summer solstice, to 44 days after it.
