Mr Strachey's letter contained some interesting observations which he has been making on the motions of the glaciers in the Himalayan mountains; and his measures, conducted on the plan of Professor Forbes in the Alps, are the earliest that have been taken in Asia. The Pinduree glacier, on which the observations were made during cold weather, was found to move 3 feet 1 inch in 5 days at the centre, and at the sides about 1 foot 5 inches.

Lieutenant Strachey's former Researches on the Glaciers of the Kumaon Himalaya (published in one of the Indian Journals), have satisfactorily proved the existence of glaciers in lat. 30° 20′, which present in detail all the phenomena of those of Europe.
