univerfally, as well as defervedly effeeraed j 
and notwithflanding the many alterations at 
different times made in the Structure of this 
Inftrument, yet on a more nice Examination 
we found it capable of very confiderable Im¬ 
provements. 
The chief Excellency of any Microfcope ? 
confifts in the Degree of the Magnifying 
Power under which the Objeds may be leen 
with Diftindnels j and the ready, and moft 
convenient placeing, the Qbjed to be viewed. 
With refped to the firft of thefe ; in the Struo* 
ture of our new Microfcope, we have load par¬ 
ticular regard, to the moft advantagious fftua-* 
tion of the Glafles, and have been able to re¬ 
medy foriit Imperfedions, which though to 
be found in all Microfcopes hitherto made, 
had efcaped being taken notice of, by which 
means the Objed is rendered more diftind 
than in any other, as we fhall be ready to fa- 
tisfy any curious Perfon deffrous of making 
the Comparifon.
