TELESCOPES. 



Mr. Henry Fitz, of the city of New- York, exhibited at our last 

 fair, an achromatic telescope, manufactured by himself, for John 

 Campbell, Esq., of this city. The object glass is eight inches, 

 the focal length, ten and a half feet, with circles of right ascen- 

 sion and declination, seven inches diameter. One peculiar fea- 

 ture in this instrument, is the plan of its mounting. The equa- 

 torial machinery is of cast iron ; the polar axis and declination 

 box being cast in one piece, as is also the saddle for the tube and 

 the declination axis ; both axes are cast hollow, which gives great 

 firmness with little weight. Its cheapness is a very great recom- 

 mendation. It is furnished with clock work for keeping the ob- 

 ject in the field of view adapted to lunar, mean, and siderial 

 time. 



A novel and most important improvement has been made, by 

 which the necessity of clamping or unclamping the tangent screw 

 (which connects the clock with the riglit ascension circle) is dis- 

 pensed with, and by which means the management of the instru- 

 ment is rendered perfectly simple and plain to persons unaccus- 

 tomed to the use of telscopes, with very little liability to be put 

 out of order, even in unpractised hands. Fur these improve- 

 ments, Mr. Fitz has applied for Letters Patent. 



This telescope is placed in an observatory on the top of Mr. 

 Campbell's dwelling house, in Sixteenth street, and stands 70 feet 

 above the surface of the ground. The observatory is of a circu-
