* With regard to fmall ftars, that become viable by an increafe of magnifying- 
power, we may furmife, that it is partly owing to the greater darknefs of the 
field of view, arifing from the increafed power, and partly to the real effe£t of 
the power; for, though the real diameter of a ftar, notwithstanding it he magnified 
a thoufand times, fhould ftill remain fmalier than the minimum vifibile, yet fince a 
ftar of thefeventh magnitude maybe feen by the naked eye, we may conclude, that 
the light of a ftar fubtends incomparably 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 fhall be juft fufficient to magaify the real diameter fo as to bring it 
within the limits of this proportion, whereby the ftar will become viable.
