Qhittagong. 



From Chittagong I have been favoured by R. Trotter, Esq. B. C. S. 

 with the following letter and register ; and in reply to some enquiries, 

 with the note which follows the register : — 



" I have the pleasure to send you the accompanying Table, contain- 

 ing a few particulars regarding the state of the weather here during 

 the late hurricane in Calcutta. I find my Sympiesometer a very deli- 

 cate instrument, indicating approaching changes. It fell to 28.70 

 during the violent squall on the 3d, about 3h. 30m. p. m.

Rain Gages, 

 by Dollond. 









The attached Thermometer stands 2° higher than the above observations, 

 t The Barometer stands about 2-10th below the standard in Calcutta. 



N-. B. I cannot account for the great difference of the results of the Rain Gages ; that used by me 

 is a plain tin box, of which the cubical contents are ascertained. The observations of 4th and 5th 

 were checked by actual measurement.
