188 Floods in India of 1849. [No. 2. 



the Barometer falling to 27.924; the lowest it had been daring the 

 season. In the course of four days, 26 inches of rain fell at the Ghaut : 

 in the same time above 40 fell at Mahabaleshwar. 



Violent rains occurred over the Southern part of the Chinese Empire 

 in May and June : up to the middle of July the fall was heavy, and 

 the Barometer low. On the 26th July, one of the most furious storms 

 of rain and hail ever known occurred over the south of England. 



Even with the limited information we possess, a multitude of singular 

 facts are here disclosed to us, one of the most striking of which is the 

 diversity in the state of the air in matter of humidity, when the rains 

 were at their wildest. Taking the crisis of the 22nd June as an exam- 

 ple we find the wet and dry bulb thermometers to have stood as 

 follows at their maxima and minima at the following places :

Then we have the air at Madras in the midst of frequent rain, 

 though not the rainy season, nearly as dry as it is with us during the 

 fair weather ; while at Aden, June seems the driest, January one of 

 the wettest months of the year. This is one of the most important 

 conditions of climate : — observations with the wet bulb are almost as 

 easily made, as with the dry-bulb thermometer — they ought on no 

 account ever to be omitted. 



The following rain returns will show the amount of fall, in inches, 

 for May, June, and July on this side of India.
