This vast accumulation of sublime peaks, the pinnacles of our globe, is so extensive, that a plane, resting on elevations 21,000 feet, may be stretched in one direction as far as the Hindoo Cosh, for upwards of 1,000 miles, above which rise loftier summits, increasing in height to nearly 6,000 feet more.
To make Gold Size.
Melt one pound of asphaltum, and pour into it another pound of linseed oil, rendered drying by litharge; add also to it half a pound of red lead or vermilion. When the varnish becomes thick or pasty, thin it by adding one pound, or a pound and a half of spirit of turpentine; as more is required in winter than in summer.
Indian Corn.
Mr. C. Hall Jessop, of Cheltenham, asserts that he "was the first who recommended the Indian corn for field culture in this country," which he did "in a letter to G. Talbot, Esq., of Guiting, seven years ago."
Polishing Stones.
The Hindoos polish all kinds of stones by means of powdered corundrum, mixed with melted lac. The mixture being allowed to cool, is shaped into oblong pieces, of three or four inches in length. The stone is polished by being sprinkled with water; and at the same time rubbed with three oblong masses; and the polish is increased by masses being used successively with finer grains.
Sensitive Plant.
Mr. Burnet and Mr. Mayo have found, that at the moment the sensitive plant is touched, so as to occasion motion, it changes colour. They have also found that when a sensitive plant has been made to droop, the part in which the moving power resides is blackened, so as to absorb the light of the sun; the restoration of the plant to its natural state is much longer in taking place.
