of a Number of fine Lines, or rather 
Bundles of Lines, beginning from Centers 
in the interior Edge of the Border, and 
fpreading out at nearly equal Diftances from 
each other every Way towards the Exterior,

the Diftances between the Lines are filled 
up with the glewy Matter, nor do the Lines 
themfelves feem detached therefrom, but 
are formed together with it. From thefe 
fame Centers are produced afterwards a 
Radiation alfo inwards towards the Middle 
of the Drop, compofed of Parallelograms 
of different Lengths and Breadths; from one 
and fometimes both the Angles whereof 
there are frequently feen Shootings fo ex¬

commonly cut off at right Angles, but they 
are fometimes alfo feen oblique. The whole

Centers with the like Radii iffuing from 
them, and fome of the glutinous Matter

and in thefe it is very frequent to find a Sort 
of fecondary Radii proceeding from fome one
