the greatest mean quantity at Poona was in Jane, and it amounted only 

 to 8-9,31 grains. In 1828, in the month of March, the following were 

 the dewing points in consecutive days, travelling from Bombay to 

 Poona: Bombay, 10th March, 4 p. m., 11-205 grains of water in a cubic 

 foot of air ; at Poona, at the same hoar, on the 14th March, 2-273 grains. 

 At Bombay, on the lOth, at sunrise, and at 9| a. m., the dewing points 

 were respectively 72° and 71°, temperature 75° and 81°-5, a cubic fool 

 of air containing 8-87;> grains at the former hour, and 8-487 grains at the 

 latter hour. The following morning at Kundallah, on the top of the 

 Ghats, 1744 feet above the sea, at the same hours, the dewing points 

 were 36° and 40°, temperature 72° and 78°, equivalent only to 2'690 

 grains, and 3"004 grains of water in a cubic foot of air. In the afternoon 

 of the same day, at Karleh, 2015 feet above the sea, seven miles east of 

 Kundallah, a cubic foot of air held 2*954 grains, and on the 12th, at 4 

 r. M., 2-611 grains of aqueous vapour. On the summit of the hill fort of 

 Loghur, 3381 feet above the sea, and 1366 above Karleh, the dewing 

 point at sunrise on the 13th, was 5° Fahr. below the freezing point, tem- 

 perature of the air 67°, and a cubic foot of air held only 1*995 grains of 

 water in a state of vapour. These facts fully establish the remarkable 

 discrepancies between the hj^grometric state of the air in Bombay and 

 Dukhun, and that too within a ditferenee of a few miles of latitude -and 

 longitude. A comparison of the absolute falls of rain in Bombay and in 

 Poona, for the years 8826-7-8, shov/s an agreement (to a certain extent) 

 in their ratio to the hygrometric state of the air at Poona and Bombay, 

 above noticed. The mean fall of rain at Bombay in those years was 

 93'G2 inches, and at Poona 26-926 inches, or 28 1 per cent, only of the 

 fall in Bombay. 



/ittm.- — In Dukhun the rains are light, uncertain, and, in all years, 

 barely sufficient for the wants of the husbandman, and a slight failure 

 occasions much distress. They usually commence at the end of May, 

 with some heavy thunder showers from E. to S. E., the lightning being 

 terrific and frequently fatal, and the wind furious ; but they do not set in 

 regularly until the first ten days in June, and continue until the end of 

 September from the W. to the S. W., and break up with thunder-storms 

 from the E. to the S. E. before the middle of October. During the re- 

 maining months of the year an accidental shower or two may fall from 

 the Coromandel monsoon ; and the farther the distance eastward from 

 Poona, the greater the chance of showers in the cold months. The 

 monsoon temperature is equable and agreeable, and the rain occurs al- 

 most always in showers, rarely continuing uninterruptedly for a day or 

 more, as is common on the coast and in the Konkun. The greatest
