Meteorology of the Goomsoor Mountains. 



[Oct. 



covered with muslin and wetted with common water, as it was found to 

 give the same indications as when wetted with distilled water. 



To test the indications of the wet bulb thermometer the black ball 

 of the hygrometer was covered with muslin, and both balls being 

 wetted the enclosed thermometer gave the same indications as the 

 small wet bulb thermometer, and therefore there appeared no reason 

 to doubt its accuracy on account of its being small. 



The barometer was a very rough instrument on the wet tube plan, 

 and the scale very imperfectly divided. The observations have there- 

 fore been given reduced to the temperature of 32° Fahrenheit. The 

 mean pressure at Chicacole at 10 a. m. was found to be 29.71 ; at Ber- 

 hampore 29.75, and at Aska 29.68, which are sufficiently accurate to 

 give confidence in the indications of the last instrument. 



The hygrometer was one on Daniel's construction made by New- 

 man, and the observations were generally repeated on any change of 

 the dew point to ensure accuracy.
