I. bed I dinmcter of S. ; with 1504, I criamcter, well- 



defined, and the difference of colours iViU vifible; with 

 2i;6, not quite a diameter of S, pretty well defined, 

 4A,ut exceedingly tremulous; with 2589, lefs than i 

 diameter; with 3168, ftill pretty diilmd, and about 

 I diameter of S ; with 4294, more than a diamtter of 

 S, but attended with the utmoft difficulty of n}anaging 

 the motions ; with 5489, the interval fiill fomewhat 

 larger, and if the obje£l could be kept in the center of the 

 field, the eye might adapt itfelf to the focus, and 

 get the better of the violent aberration ; but J-he edges 

 of the glafs being of a different focus, the eye is con- 

 ftantly difappointed in its endeavours to define the ob- 

 je6t ; with 6652, I had but a fingle glimpfe of the ftar 

 ^uite disfigured; however, I afcribe it chiefly to tho 

 foulnefs of the glafs, which, on account of its fmall- 

 nefs, is extremely difficult to be cleaned; withaio-feet 

 refle£lor, 9 inches aperture, power 626, above \ dia- 

 meter of S. very diffind ; with a 20-feet reflector, 

 power 350, too bright an obje6t to be quite diftincly 

 though I fee it very well. Pofition 5° 24'' n. following,
