 and changes in the atmosphere are as follows, during the 350 days 

 on which observations were recorded. Clear 1 14.3, generally clear, 

 i. e. presenting only such slight appearances of vapour in some part 

 of the horizon, as not to deserve to be ranked under any definite 

 term, 12.8, cirro strati 21.3, cirro cumuli 16.8, cumulo strati 41.6, 

 cumuli 35.5, rain 12.3, cloudy 73.8, foggy 3.3, nimbi 10.8, haze 5.3.

Under the head of cloudy, are comprehended those appearances 

 which, form the opacity of the air could not be arranged under any 

 of the definite forms of clouds. There is an obscurity likewise in 

 the distinction of fogs and mists and haze, in these registers, which 

 ought not to exist, as such terms indicate very opposite conditions of 

 the atmosphere. 



It is only necessary to allude to the circumstance in order to 

 invite the very able attention of Mr. Rees to the subject, who I be- 

 lieve has the merit of superintending these important Registers. 

 The term Haze, as it ought at least to be used in India, indicates an 

 excessively dry condition of the atmosphere, at periods of heat and 

 drought. See vol. 1. p. 52, of this Journal.
