Description of' a New Reflecting Telescope, denominated the 

 Aerial Rejlector. By Thomas Dick, Esq. Author of the 

 Christian Philosopher, &c. Communicated by the Author. 



X HE invention of the Reflecting Telescope was an important 

 improvement on the long and unwieldy refractors, which were 

 in use among astronomers towards the close of the 17th century. 

 With a Newtonian reflector, only six feet long, celestial objects 

 may be viewed with as high a magnifying power, and with equal 

 distinctness, as with a common refracting telescope of 120 feet 

 in length. By means of these instruments, the late Dr Her- 

 schel made those brilliant discoveries which have extended our 

 views of the solar system, and of the grandeur of the universe, 

 and which have rendered his name immortal in the annals of as- 

 tronomy. It was not a little singular, however, that more than 

 half a century elapsed, after the construction of this instrument 

 was suggested by Gregory and Newton, before any reflecting 

 telescope of a size calculated for celestial observation was actual- 

 ly constructed. In the year 1663, Mr James Gregory of Aber- 

 deen pubhshed his account of the construction of that form of 

 the reflecting telescope, which bears his name, in a treatise en- 

 titled " Optica promota ;" and in the year 167^, Sir Isaac New- 

 ton constructed two small reflecting telescopes, about six inches 



• The herring, mackerel, and whale, are in abundance at Newfoundland, 

 and comparatively allowed to pass unmolested. The herring varies in size, 

 from small to several pounds weight. The whale is of three or four kinds, 

 and the fishery of it is prosecuted only by one enterprizing English mercan- 

 tile house at the south part of the island; the whales have been taken up- 

 wards of 70 feet in length, Yielding from six to eight tons of oil. The salmon 

 abounds in all the rivers, and is taken in large quantities. The dog-fish 

 sometimes occurs with the cod in great numbers.
