The micro/cope explained. 
A new compendious pocket microfcope. 
T HIS inftrument being an abridgment of the varia¬ 
ble microfcope, is contrived for the pocket, that 
it may be ready when gentlemen and ladies are amuAng 
tbemfelves in their gardens, parks, &c. to infpedt, and 
collect fuch objedfs as may be proper to preferve for a 
future examination, to be viewed in the variable microf¬ 
cope, fig. i. and 2. or to delineate them by help of the 
camera microfcope, fig. 6. or 7. either in the fun Aline, 
or in long winter evenings. 
ABC, fig. 21. No. A. reprefents the body of the 
microfcope, containing two eye glafles at A, a third at B, 
and a fourth glafs between B and C, at the end C, is 
feen the dove tail into which the brafs Aider F that 
contains the fix magnifiers, is to be put. The numbers 
I, 2, 3, &c, being placed at the extremity of the dove¬ 
tail at C, the magnifiers correfponding to each number, 
will then be under the center of the body of the microf¬ 
cope, the leaft number is the greateft magnifier, 
This microfcope in its compound flate has the property 
of increafing the field of view and the light; as has been 
iliewn in page ii. in the defcription of the variable 
microfcope, as well as that of increafing the magnifying 
power of each particular magnifier. 
The compound body ABC, is fupported by an arm 
N O, into which at C, it may be fcrewed or taken 
out occafionally. This arm N O, Aides backwards or 
forwards into the box P, which turns round on the 
top of the moveable pillar R, by which double motion 
every part of an objedt of tfie fize of the fcage D D may 
f>e readily examined. 
The Aiding bar R may be raifed or deprefied by turn¬ 
ing the ivory head I, fo as to adjufi: the body of the mi-
