TO CORRESPONDENTS.
Edward Haydock.—Declined with thanks. li. N. Martin and "J.C."—We cannot afford space for further correspondence on the subject. "J.D."—The theory to which you refer—that the comet-tail is a beam ot sunlight projected through fine reflecting particles—has in various'forms, had many advocates, but. has met with no support from men of science. A fatal objection is, that it presupjioses some kind of lens or pinholecamer.i arrangement, as in the ease where v sunbeam enters a dark room through a shutter. But such a shaft of light, unlike a comet, is perfectly straight. Moreover, it is now known that a comet gives forth inherent as well as reflected light.
