* With regard to fmall fiars, that become vlfible ty an increafe of* magnifyiBg 

 prower, vf^ msy fnrmife, t'hat it is partly owing to the greater darlcnefs of the 

 field of view, arifing from the increafed power, and partly to the real efFeft of 

 the power; for, though the real diameter of a ftar, notwithftanding it he magnified 

 a.thoufand times, fhould ftill remain faialler than the minimum vifibile, yet fince a 

 Irar of the feventh magnitude maybe feen by the naked eye, we may conclude, that 

 the light of a ftar fubtends iincomparably a larger angle than its luminous body ; 

 and this may be in fuch a proportion, with very fmall ftars, that the power of 

 the telefcope fliall be jufl fufiicient to magnify the real diameter fo a« to bring it 

 '^vithin the limits pf this proportion, wherel?;^, U>e flar will become vilible.,
