All thefe, and numberlefs Wonders more, 
the Microscope can exhibit to us. I (hall 
therefore proceed to defcribe this noble In¬ 
vention , fliew how far it is improved at 
prefent, give a brief Account of what Dif- 
coveries have been made, and point out 
fome Objects for the Curious to examine 
by it. In doing this, I (hall avoid as much 
as poflible all Affectation of Learning, or 
Expreffions that are not in common Speech, 
being defirous that every body may under- 
Hand me.
