254 REPORT—1852. 
except Goruckpore, and at 1050 feet above the level of the sea. The next 
group is in the N.W. Provinces, and consists of 18 stations, from lat. 21° 51’ 
Baitool to lat. 27° 23' Futteghur, and from long. 77° 45' Hoshungabad to long. 
81° 54! Allahabad. The highest mean temperature is 103° in May at Myn- 
poorie, lat. 27° 1', and 100°-1 at Allahabad and Nursingpore, the former in 
lat. 25° 27' on the confluence of the Ganges and Jumna. The daily mean 
temperatures run very high in May and June at all the stations in this group. 
The Agra group, embracing Rajpootana, has 9 stations, but the observations 
are incomplete. The highest mean daily temperature at Agra, lat. 27° 10', 
was 96°°1 in June. The Meerut and Delhi group has 13 stations, embra- 
cing Almorah at 5500 feet, from Budaon, lat..27° 50', to Deyrah, lat. 30° 19’, 
and from Delhi, long. 77° 13', to Almorah, long. 79° 41'. The highest 
mean temperature is 104° at Goorgaon, 38 miles south of Delhi, lat. 27° 53’, 
in June, and at Delhi, lat. 28° 31', the temperature in May is 98°°6. 
The Umballa group of 11 stations embraces Simla, at 7500 feet, and other 
hill stations. At Ferozepore, on the Sutlege and Simla, differing 9 miles, in 
lat. 30° 57! and 31° 6’, the highest mean temperature at both is respectively 
in June, 97°°5 and 69°:2; the difference of elevation giving 220 feet for each 
degree of difference of temperature in the month of June; but in the month of 
January the difference of mean daily temperatures, 40° and 55°-9, gives 397 
feet for each degree of temperature. The last group takes us to the Punjab, 
where there are 25 stations between Mooltan, lat. 30° 10', and Peshawur, lat. 
34° 0', and Kohat, long. 71° 26’, to long. 76° 19' Kangra. Lahore in this group 
is 1180 feet above the sea, and Peshawur 1068; and I presume none of the 
stations, excepting probably Mooltan, have a lower elevation than these. The 
returns are defective, but it would appear a very high daily mean temperature 
exists in somemonths, notwithstanding the comparatively high latitude; Mooltan, 
lat. 30° 10’, temp. 99°°4; Jehlum, lat. 32°55', temp. 97°; and Mean Meer, at 
Lahore, lat. 31° 33', temp. 98°°2, allin June. The general results would seem 
to indicate that the daily mean temperature in the summer months increases 
with the latitude ; that is to say, that the daily mean temperature in lat: 32° 
in June, July and August, is greater than in lat. 22°. The rain-fall manifests 
in a marked manner, as I have formerly had occasion to show, the great discre- 
pancies in the fall-within very limited areas ; and in the increase in the fall up 
to certain maximum elevations. In the case of Calcutta and Barrackpore, only 
9 miles separate in latitude and 44 in longitude, the fall of rain respectively 
for 1851 was 64°16 and 42°75, differing 22 inches. Hooghly is 20 miles N. 
of Calcutta, and differs only 6 miles in longitude, but the fall was only 36 
inches, differing from Calcutta 28 inches. Barrackpore is intermediate between 
Calcutta and Hooghly, and only 13 mile west of the longitude of Barrackpore, 
but the difference in the rain-fall is 62 inches. All these three places are on 
the Ganges, on the same level, about 20 feet above the sea. Burdwan, which 
is 40 miles N. of Calcutta and 28 miles W., had only a fall of 28 inches ; but 
more remarkable still, Midnapore, 8 miles south of Calcutta and 59 west of it, 
had only 22°78 inches; while Cuttack, 76 miles south and 13° of longitude 
west, had 50°17 inches. In the Dacca group, which contains the hill station 
of Cherraponjie in the Cossya hills, the most extraordinary discrepancies occur. 
Chittagong, only 13 miles south of the latitude of Calcutta, but 33° to the E., 
has 86°33 inches of rain, and lying under the same meridian as Cherraponjie, 
which is 116 miles N. of Chittagong, at an elevation of 4500 feet, it has 
524-02 inches of rain less than Cherraponjie, at which station the almost 
incredible quantity of 610°35 inches fell in 1851; and that this deluge is 
no mistake of record, independently of the official report which I quote, I have 
a letter from Professor Oldham in confirmation of the fact, who spent the mon-
