IS the iris, or bow, confifting of fmall tubes* like 
rays darting around ; and between thefe very fmall 
downy ftrings, through a mictofcope, or fometime3 
with the naked eye, we may perceive a number of 
little flight and foft grains, appearing to crown the 
whole circle, as it were with a ray of glory, in 
a manner that difplays the moll brilliant colours in 
man and other animals. In fome creatures this per- 
fect fymmetry is fo ftriking, as to prefent a fet of 
regular figures to the philofophic eye ; nor, indeed, 
can fuch a fight be ferioully contemplated, without 
thofe pleafing fenfations which attend refearches 
into the fecrets of Nature. 
The eye fliares the motions of the foul ; exprefb 
ing all its feelings, llorms, and agitations, in fuch 
true language, as rapidly communicates every im- 
preliion to the beholder whofe heart is open to it 
and fufceptible of fympathy ; while thus fentimen- 
tal fpirit, found fenfe, and clear ideas, are convey- 
ed with the force of lightning. 
Much as the fire or languor of the eyes contri- 
butes to fiamp the leading features with their dillin- 
guithing perfe£fion, and although they ftrike us as 
if they moved in all directions, they have, how- 
ever, but one circular motion in turning about their 
center, which they do in fuch a way, that the pupil 
appears to go up and down, according as it ap- 
p’Q-jches or removes from the angles.
