THE SUN’S HEAT.
[To the Editoe] . Sib, “ Amateur ” nearest the truth when he says that light is the source of heat; notwithstanding the arguments of “ H.W.H.” about the spectroscope, which merely proves that the gases or vapors surrounding the sun have similar elements to the metals of this earth. This suggests the enquiry, what is light? Sir John Horschell tells us that “light is the great creative agency; that it is a movement having a measurable velocity, which enters chemically into (ho composition of everything; that when in union v ith our atmosphere or the earth’s gases, it produces heat. The diamond is crystalised light, and coal has been called bottled up sunshine. Light is the cause of all color, and it leads towards the perception of those powers which maintain all material things ; while from the material light we may learn by analogy something about that spiritual light which is God’s best gift to men. I will conclude with asking whether the Mechanics’ Institute could be utilised for the consideration of this or similar subjects.—Yours, &c., W.B. Timaru, Maj 2nd, 1883.
