long white Worm^cameoin of rhc Earth, which feachn^ 
apd inciirvaring their botlies,».fubfided kifurtly tothc bot- 
tom oF the Tube, non^ oi ^bcm bein^ able to emerge to 
the (uperficits, vyhence I <*c :d that they couJd. not 
live in the Water ^ 'Bivd' in ti;od/, afcer they had lain C4 
Hours in the bottom of the Gfaft, 1 found they were all 
dead. . • 
It feemVi to ir^e alfb that thefe white Worms confifted of 
fevcral fizes or magnitudes, and that thcy could not be the 
Oitfpringcf our common Worms bceaufe they were 
mudi longer, in proportion to their bigncfs. 
I faw likewife a common Worm creeping out of the 
abovefaid Earth, which leifurely fubfided and remained 
at the bottom ot the Tube with little or no motion, and 
the next day it was dead. ' - 
As for thofe fmall Ammdcula that came out of the Earthy " 
and fwam about the Water, they were of fo many fevc- 
raUorts and fizes, that the defciiption of them would 
take up too much room, bcfides fome of thefe AfiimalcuU 
w^ere fo exceeding fmall, thot 1 could not perceive what fi^ 
gpretheywere of, tho I viewed them veiy nicely and 
very frequently, nay, tho I (hifted the Earth and Water 
tfiree times. 
Now that thefe may be call dW^ater* worms, 
tho they are found in thedrycft part of the Earth, ap* 
pears from their living fo well in the Tube filled with Wa* 
ter, in which, tho I obferv'd them day after day^ I found 
tio difference in them, fave that they were encreaft in 
ntfmber, and befides I have met m ith feveral of them in 
common Water. 
In thefe Obfervations I difcovered a few particles of 
Sand mixt with Cliay, the fides of hich appear'd as if they 
had been broken or grated off from Stones, and fome cf 
them w^refo veryfmail,that above a thoufand of them to. 
gether did not exceed the magnitude of a finglc grain of 
common Sand that is us'd in Scowring, ^r.
