VI. — On the relations of cloud and rainfall to temperature in India, and 

 on the opposite variations of density in the higher and lower atmos- 

 pheric strata. — By Henry F. Blanford, F. R S., Meteorological 

 Reporter to the Government of India.

In the Report on the Meteorology of the year 1879, which I drew up 

 last autumn, and which will shortly be issued, I had occasion to discuss 

 the two subjects enumerated in the above title, in connection with the 

 anomalous variations of temperature and barometric pressure, exhibited by 

 the Indian registers during the last two or three years. As, however, they 

 have a much wider bearing than merely in reference to the cotemporary 

 phases of our Meteorology, and indeed may claim to rank among the 

 more important physical operations which influence Indian Meteorology, 

 I have thought that it might be of interest to extract these notices from 

 their original setting in the pages of the Annual Report, and to ask the 

 Society to give them an independent circulation in its Journal. 



I have been the more prompted to do this, because, in a recent number 

 of the Journal of the London Meteorological Society,* Mr. Douglas 

 Archibald has discussed at length a nearly cognate subject, viz., the " Varia- 

 tions in the barometric weight of the Lower Atmospheric Strata in India." 

 In this paper, Mr. Archibald refers to certain articles which the late Mr.

 the 19th May 1880.
