APPENDIX K.

ACTTNOMETER OBSERVATIONS.

The few actinometer observations which I was enabled to record, were made with two of these instruments constructed by Barrow, and had the bulbs of their thermometers plunged into the fluid of the chamber.

They were taken with the greatest care, in conformity with all the

rules laid down in the "Admiralty Guide," and may, I think, be

depended upon. In the Sikkim Himalaya, a cloudless day, and one

admitting of more than a few hours' consecutive observations, never occurs--a day fit for any observation at all is very, rare indeed.

I may mention here that a small stock of ammonia-sulphate of copper in crystals should be supplied with this instrument, also a wire and brush for cleaning, and a bottle with liquid ammonia: all of which

might be packed in the box.
