days, examining the geological structure of the Sewalik range. I 

 obtained many interesting tertiary fossils from various localities in 

 the Sewaliks. 



I marched through Dugshaie to Simla, where I arrived on the 

 25th of March. 



The observations made in the outer ranges of the Himalayas, and 

 in various localities in the environs of Simla, will be reserved for 

 the next Report, treating of the Himalayas. 



Meteorology. 



Besides the daily registry of dry and wet bulb thermometers and 

 barometers, whilst on the march, a longer 

 Temperature of the gerieg of otservat i ons were made at s augorj 



Bermhan, Jubbulpore and Umerkuntuk ; at 

 Sohagpore, Allahabad, Agra and Simla. These observations seem 

 to lead to the following conclusions. 



The minimum temperature of the air was very regularly observ- 

 ed to set in just before sun-rise, but there

sion of temperature immediately after sun- 

 rise, as we had observed in the Indian Seas in October 1 854. 



The increase of temperature from sun-rise up to 11 o'clock a. m. 

 is especially rapid between the hours of 8 and 9. a. m. I often no- 

 ticed an increase of temperature of 4 to 5 degrees centigrade be- 

 tween these two hours. 



The total increase from sun-rise to 11 o'clock was, at Saugor, 

 (15th to 19th December,) as much as 28 degrees centigrade ; at 

 Jubbulpore it was from 12 to 15 degrees ; but at Umerkuntuk 

 (20th to 26th January) the difference between sun-rise and 11 

 o'clock a. m. was only 8J to 9 degrees centigrade. Between 11 

 A. m. and 4 p. m., the variation of temperature was generally not 

 very great — not more than 3 or 4 degrees centigrade ; but the de- 

 crease of temperature between 4 p. m. and 7 p. m. was very rapid. 



East of Jubbulpore, at Ramgurh, and as far as Umerkuntuk the 

 minimum temperature of the day was very near the freezing point; 

 but I never observed a temperature lower than 32 degrees Fahren- 

 heit, or 0 degrees centigrade.
