IV. — Climaff o/Sfriffgapatnm. Latitude 12»45' N. Long'. 76°5r E. 

 (Extracted from the Journal of the Asiatic Society of Bc/ngal.) 



Beinc: desirous of incUidinG^ within the pag-es of the Journal all 

 the data nGce>»sa> v fi)r a uicteoroloj,ist, to judge of the contingencies 

 of pressure and temperature on the whole continent of India, we 

 extract the following results of a meteorolo<:ical journal, kept for 

 two years at Seringapatam, from Bre water's Edinburgh Journal of 

 Science, Xo. 5. 



The original registers were kept by Mr. Scarman in 1814 and 

 1316. They were abstracted and reduced to order by Mr. J. 

 Fog GO, Junior. 



The mean temperature of the whole year is by observation 77 06° 

 The mean at sunrise is 63°. 17: at 3 p. m. 90o.95 : — of the day, 

 84", of the night, 70 ,11. The average daily range of temperature 

 27'>.7. The curve of mean temperature has two convex summits, 

 m May and October, corresponding with the sun's passage twice 

 over the latitude of the place. The highest temperature is 115*>, 

 and the lowest, 4S<'. 



The mean temperature of the river Ceiveri, observed every day at 

 6 A. M. and 6 p. m. is 77 2 agreeing exactly with that of the air. 



The averao^e height of the barometer is 27.568, whence the 

 elevation of Seringapatam may be calculated to be 2412 feet above 

 the sea, assuming the sea level, 29.88, and the temperature of the 

 intercepted column of air, 78**, 



The average diurnal tide between the hour of 10 a, m, and 4 

 p. M. is 0.074 inch. During the prevalence of the south-west mon- 

 soon, the extent of the variation is diminished. The monthly 

 variation also proceeds with great regularity, the whole range beinp: 

 0.262. For the la^t three months of 1816, the register was extended 

 to the hour of 8 p. m. and the average height of the barometer at 

 that hour is 0 006 lower than at 4 a. m, 



Tne prevailing winds are the north-east and south-west, or the 

 general monsoons of the Indian Ocean. The south-west sets in 

 during the month of April. When it commences, its reciprocation 

 "with the north-east wind interrupts the serenity of the weather ; 

 and during its contTiuance, thunder storms occur almost every day, 

 "with heat-lightning at night. This is the rainy season, but the 

 monsoon having deposited its superabundant moisture upon the 

 ghats, very little rain falls at Seringapatam. During the north-east
