METEOEOLOGV. 



The atmosphere of India is chiefly tropical' a small ex- 

 tent only being situated in the southern part of the northern 

 temperate zone. In some districts, however, the atmo- 

 sphere, owing to the form, elevation, and nature of the sur- 

 face of the land, exhibits characters almost identical with 

 those of the northern temperate, and even of the polar 

 regions. To place ih full array before our readers a com- 

 plete view of a subject so vast and complicated as the me- 

 teorology of India would very far exceed the limits of the 

 present work. We must therefore rest satislied with the fol- 

 lowing details and views, which will illustrate, in a popular 

 view, the meteorology of Kindostan : — 



1. Changes in ihe Pressure of the Atmosphere.— The 

 changes in the pressure of the atmosphere, as ascertained 

 by means of the barometer, have not in India been traced 

 out with that care and accuracy which the importance of 

 the subject demands. Of the barometric phenomena, the 

 rnost curious are those that point out the daily atmospheric 

 tides, the horary motions, or the double rise and fall of the 

 barometer within twenty-four hours. In India, as in the 

 temrerate and arctic regions, there are daily or hourly varia-
