The physical geography of the sea, and its meteorology . ° .0 1 1 i 1 able accuracy, not only the relative strength of the north-eastand south-west monsoons of the sea, but also the mean height ofthe barometer in the interior of India during the south-westmonsoon, supposing that monsoon to go no farther than themountain range, which may be taken at a mean to be about theparallel of 30° north. Now, taking the mean height of thebarometer at the equatorial calm belt to be (§ 362) inches ;the mean height in the calm belt of Cancer to be inches,the line of the Diagram D will represent the average baro-metric declivity of the north-east monsoons generally.

This barometric declivitymdicates that the south-west are stronger than the north-eastmonsoons, and observations show that they are.* 692. The summer rains of Cherraponjie.âTheEiQ are the windsâthe south-west monsoonsâwhich, coming from the sea, carryinto the interior rains for the great water-shed of India. Theybear with them an immense volume of vapour, as is shown by therivers, and confirmed by the rain-fall of Cherraponjie, and at126 other stations. Cherraponjie is 4,500 feet above the sealevel. ^ It reaches quite up to the cloud region, and receives aprecipitation of 537i inches during the south-west monsoon,trom May to August inclusive. Col. Sykes reported to thel^ritish Association, at its meeting in 1852, the rain-fall at these1^7 places, which are between the parallels of 20^ and 34° inIndia. According to t
