June I r, 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 fhewed the flar wedge-formed.

 July 22, Double. About j degree n. following <p ; in a line 

 1782. parallel to the 35th and 42d Herculis; the mofl: fouth 

 of two very fmall telefcopic ftars. Confiderably une- 

 qual. Both reddifh. V/ith 227, they can but juft be 

 feen as two ftars ; with 460, near i diameter ; with 

 932, not lefs than i| diameter of L. Pofition 59*^48' 

 f. following. 



* The interval between very unequal ftars, eftinaated in diameters, generally 

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

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

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

 i6th, 28, 33, 45, 46, 73, Siftftars. However, this only feems to take place 

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

 removed by magnifying more, the diftance is, ns it were, laid open to the view.
