*These are taken from Dr. Chapman's Table; and present a greater

annual range (=0.169) than my observations in 1848-9, taken at Mr.

Hodgson's, which is higher than Dr. Chapman's; or Mr. Muller's, which is a little lower, and very near.

Horary Observations at Jillapahar, Dorjiling, Alt. 7,430 feet.
