*' With regard to fniall ftars, that become vifible by an increafe of magnifyino' 

 power, w€ 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 efFeft of- 

 the power,; for, though the real diameter of a ftar, notwithilanding it be magnified 

 a thoufand times, fliould itill remain fmaller than the minrmum vifibile, yet fince a 

 Ibr of thefeventh magnitude maybe feen by the naked eye, we may conclude, that 

 the light of a ftar fubtends incomparr^bly a larger angle than its luminous body ; 

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

 the telefcope fliall be juft fuiFicient to magnify the real diameter fo as to bring it 

 with ill the limits of this proportionj wheteby the Har will become vifible.
