* The interval between very unequal liars, eftimated in diameters, generally 
gains more by an increafe of magnifying power than the apparent diftance of rhofc 
which are nearer of a lize. Inflances of the former may be found in the tuft 
clafs, the 1 ft, 7, 29 ? 35 , 37 , 39 , 53 , 59 , 6 3 > 6 4 , 72<1 ftars; of the latter, the 
16th, 28, 33, 45, 46, 73, 8 ill ftars. 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, as it were, laid open to the view.
