METEOROLOGY. 



i. Great Fall of Rain at Bombay. — In a letter from Mr 

 ^coiijun. of Bombay, he says, that, during the first twehe days 

 of the rainy season, 32 inches of rain fell, and that then all the

3. Melted Snow employed as Drink. — A fact related by Cap-

 lar swellings to which, according to the common opinion, they 

 should have been exposed by employing this beverage. 



4. Notice regarding the Falls of Rewah, and a remarkable 

 Conical Hill at Myhnr. — I left Benares with my regiment on 

 the 5th of October, and arrived at Jubbulpoor on the 9th of 

 November 1826. Our route lay through Mizapoor, Rewah, 

 and Myhur. When at Rewah, I left the corps for two days, 

 and, in company with some of our officers and their ladies, went 

 to visit the stupendous falls of the Lounse, or Loonse, generally 

 called the falls of Rewah. They are three in number, and the
