a tent and not far from the house, was 27°, when the other was 38° 5’.

In connection with the thermometric observations at Saharunpore in the open plains of Upper India, 
it is interesting to give that of the Deyra Valley, in the same latitude, and about forty-five miles to the 
east. The observations were made by my late friend, the Hon. F. Shore, while Assistant Commissioner 
in the Deyra Doon.

From the greater number of cloudy days, as well as from the greater moistness of the climate, it is 
found difficult to ripen some fruits which succeed in the plains, though others, as Bengal Plantain, 
Guavas, and several varieties of Limes, arrive at greater perfection. The greater degree of moisture must 
be ascribed to the surrounding mountains, and to the quantity of vegetation with which the uncleared 
parts of the valley are covered. Like other vallies, it is also more close, as the winds cannot blow so 
freely as in the open plains. The evenings and nights are, however, pleasant, as a cool breeze generally 
descends from the mountains, and at some seasons of the year the climate is delightful. 
In the ascent of the Himalayas, in the course of the Geological section, Jurreepanee is a mid-way 
station, where I have occasionally taken observations, and of which the temperature feels cool to those 
who are ascending, but warm to those descending from, the mountains :

Mussooree and Landour are on the elevated range which rises immediately above the Deyra Doon, and 
where a Sanatarium for the recovery of the health of European soldiers has been established, as well as 
houses built by officers, and where I established a small Nursery-garden, which was abolished by Lord 
William Bentinck, but re-established by Lord Auckland. The range enjoys a delightful climate, presenting 
as great a degree of equability of temperature from summer to winter, and from day to night, as is desirable. 
In summer the temperature is low, and all accumulation of heat is prevented by the coolness of the breeze 
which ascends from the vallies. The transition to the rains, which commence about the 15th of J une, 
makes but little difference in the temperature, and the climate is remarkably equable ; and though moist 
_ and usually cloudy, it is not otherwise disagreeable or unhealthy. In the month of October, or at the 
‘conclusion of the rainy season, and throughout November, the sky is so clear and serene, the air so mild 
and still, that the climate is perfectly delightful. The approach of the cold is so gradual, and its degree 
so moderate, as to be well calculated to brace the system, when improved by a previous residence in the 
hills. The coldest months are December, January, and February ; in the last the greatest cold, and some- 
times snow-storms, occur ; after this, the rise in temperature is very rapid. Though 5,500 and 6,000 feet 
more elevated, the minimum, however, is very little lower than at Saharunpore. 
The Author has already said, “that the cold of winter in these mountains, at least on the Mussooree 
Range, is not in proportion to the coolness of summer, It may be said, that with a winter temperature
