Micrographia Illuftrata: 
OR THE 
MICROSCOPE 
EXPLAINED. 
A defcription of the new variable microfcope. 
Y this microfcope we are enabled to examine 
^ B Y& the ftructure, and difcover the various and 
furpriling contrivances, in the exaft and uni- 
sz fp r m proportion of the minute parts of the 
creation; either in animals, infedts, foffils, or vegeta¬ 
bles, &c. 
We owe the conftrudtion of the variable microfcope to 
the ingenuity and generofity of a noble perfon. The 
apparatus belonging to it is more convenient, more 
certain, and more extenfive than that of any other at 
prefent extant; confequently the advantage and pleafure 
attending the obfervations in viewing cbjedts through it, 
muft be as extenfive in proportion. I fhall not detain 
the reader with dwelling upon its merits, but leaving the 
inftrument to fpeak for itfelf proceed to a defcription of 
its feveral parts. . '•
