HERSCHEL'S TELESCOPE.
(To the Editor of the Mirror.)
Your correspondent, a Constant Reader, in No. 330 of the MIRROR, is informed that the identical telescope which he mentions is now in the possession of Mr. J. Davies, optician, 101, High-street, Mary-le-bone, where it may be seen in a finished and perfect state. It is reckoned the best and most complete of its size in Europe.
It was ordered to be made for his late majesty George III. as a challenge against the late Dr. Herschel's; but was prevented from being completed till some time after. The metals, 9-1/4 inches in diameter, having a diagonal eye-piece, four eye tubes of different magnifying powers, and three small specula of various radii, were made by Mr. Watson.
