of exactly round Eggs, which were ftuck very faft to the fides of it, and 
in fo exactly regular and clofe an order, that made me call to mindm 
Hypothefis; which had formerly thought on for the making out of all the 
regular Figures of Salt,which I have elfewhere hinted 5 for here I found 
all of them rang’d into a moft exact triagonal order, much after the man-

found after a little time to be hatch‘d, and out of them to come amulti- 
tude of {mall Worms, very much refembling. young Silk-worms, leaving 
all their thin hollow fhells behind them, {ticking on the Box in their tri-

Of thefe Eggs, a large and lufty-Fly will at one time lay neerfour or

And though the head before defcrib’d be that of a grey DroneFly; 
yet for the mainit is very agreeable to this. The things wherein’ they 
differ moft, will be eafily enough found by the following particulars: »

of the Dron-Fly, in proportion to the head. "979 agit
