of fall round Balls, exactly Globular, and very much refembling Pearls, 
namely, CCCC, of thefe there may be multitudes obferv'd in Sage, 
and feveral other Plants, which I fuppofe was the reafon why Athanafins 
Kircher fuppofed them to be all cover'd with Spiders Eggs, or young 
Spiders, which indeed is nothing elfe but fome kind of gummous exfu- 
dation,which is always much of the fame bignefs. At firft fight of thefe,] 
confefs, I imagin’d that they might have been fome kind of matrices,’or 
nourifhing receptacles for fome {mall Infect, juft as I have found Oak- 
apples, and multitudes. of fuch other large excrefcencies on the leaves 
and other partsof Trees and fhrubs to be for Flyes, and divers other In- 
fects, but obferving them to be there all the year, and fcarce at all to 
change their magnitude, that conjecture feem'd not fo probable. But | 
what ever be the ufe of it, it affords a very pleafant object through the 
Microfcope, and may, perhaps, upon further examination, prove very 
luciferous.
