Excerpt: ... latter, as proved by the schorl impressing the quartz. The author, from a careful examination of the schorls in the quartzite of Aberdeen, was led to believe that the quartz, while in the process of crystallization, expanded one twenty-fourth of its bulk, a force which appeared to him to be sufficient to cause all the upheavals and disruptions which had led geologists to account for such phenomena by a molten condition of the primary rocks. If this view is correct, and if the highest peak is granite, as the lowest is known to be granite, the author calculated that as the highest mountain is only TT part of the radius of the earth, a thickness of the crust of 168 miles is quite sufficient to yield expansive force to raise the highest peak of the Himalayan range. He further stated that the cause of the temperature at which the fluids were confined being higher than the normal one, depended on the rise of temperature which takes place during solidification. The author, in conclusion, trusted he would soon be in a position to confirm these views when he had finished the investigation of the trap rocks with which he is now engaged. 2. Notes of Excursions to the Higher Ranges of the Anamalai Hills, South India, in 1858 and 1859. By Hugh Cleghorn, M.D., F.L.S., Conservator of Forests, Madras Presidency.
