June II, Double. Very unequal. L. w. ; S. d. With 460, 

 1782. 1 1 diameter of L. As the fituation Is too low for 460, 

 I tried 227, but it only (hewed the ftar wedge- formed.

July 22, Double. About f degree n. following (p ; in a line 



1782. parallel to the 35th and 42d Herculis ; the moft foutii 

 of two very fmall telefcopic flars. Confiderably une- 

 qual. Both reddifti. With 227, they can but juft be 

 feen as twoftars; with 460, near i diameter; with 

 932, not lefs than i| diameter of L. Poiiti'on ^9^48^

* The inten^al between very unequal flars, eftimated in diameters, generally 

 gains more by an increafe of magnifying power than the apparent diftance of thofe 

 which' are nearer of a fize. Inllances of the former may be found in the firft 

 clafs, the ift, 7, 29, 35, 37, 39, 53, 59, 63, 64, 72dlT:ars; of the latter, the 

 i6th, 28, '^'^<, 45, 46, 73, 8111 liars. However, this only feems to take place 

 when there is a difficulty of feeing the objed well with a low power, which being 

 removed by magtiifying more, the diitance is, as it were, laid open to the view. '
