£0$ Of the Oyftefi 
Cryffalme, Its back like an eel Gripped of Its {kin; the 
fecond was red, refembling the common glow-worm, 
with folds on its back, legs like the former, and a nofe 
like that of a dog’s, and one eye; the third fort v/as 
fpeckled, with a head like a foal, and many tufts of 
whitifh hair on its fides. There was a bigger fpecies, 
that was greyilh with a big head, and two horns like 
thofe of a fnail ; it had feven or eight whitifh feet, but 
thefe ihined not. 
The two former confifl of a matter eafily diffolvable, 
the leaft touch turning them into a vifcous and aqueous 
matter, which falling from the fhell, {luck to the ob- 
ferver’s fingers, and {hone there for twenty feconds. If 
any part of it fell to the ground it appeared like a {mail 
piece of flaming brimflone, and when fhook off nimbly, 
it feemed a fmall Ihining line, which was diffipated be¬ 
fore it reached the ground. Some of it was. whitifh, fome 
reddifh, but both afforded a violet colour to the eye. The 
worms give no light when irritated $ and if they do, it 
lafis but a little while: whereas in thofe that are not 
provoked, it continues a good while. 
As tainted flefh, rotten wood, bodies of lobfters, and 
fome other kinds of fifhes, and other fubftances, are 
fometimes found to fhine with a light refembling the' 
foregoing, may it not probably proceed from the fame 
eaufe, viz. from animalcules ? Some have alfo fuppofed, 
that the Ignis Fatuus, will in a wilp, or jack in a lant- 
horn, is nothing elfe but a fwarm of minute infedls, 
that emit light round them in the manner glow-worms 
do.
