id, fort had the fliape of B. thefe fpun about like a Top, 
and took a courfe fometimes on one fide, as isfhown at 
G. andZ). they were more in number than the firft. In 
the id. fort I could not well diftinguifh the Figure^ for 
fometimes it leem'd to be an Oval, and other times a 
Circle. Thefe were fofmall that they feem'd no bigger 
than £. and therewithal fo fwift, that I can compare 
them to nothing better than a (warm of Flies or Gnats, 
flying and turning among one another m a fmall fpace> 
Of this fort I believe there might be many thoufands in a 
quantity of water no bigger than a (and, tho the flower 
were but the ^th. part of the water or fpittle containing it.. 
Befides thefe Animals there were a great quantity of 
flreaks or thredsof different lengths, but like thicknefs^ 
lying confufedly together, fome bent, and others fl:reight 
asat-F. Thefe had no motion or life in them, for I well 
obferved them, having formerly feen live^ Animals ia 
water of the fame figure. 
I obferved theSpittle of two feveralwomen,whofe Teeth 
were kept clean, and there were no Animals in the fpittle; 
but the meal between the teeth, being mixt with water, 
( as before ) I found the Animals above defcribed^ as al- 
io the long particles. 
The Spittle of a Child of 8 years old had no living 
Creatures in it, but the meal between the Teeth, had a 
great many of the Animals above deicribed, together 
with the fl:reak5. 
The Spittle of an oldMan that had lived loberly, had 
no Animals in it; But the lubilance upon and between 
his Teeth, had a great many living Creatures, fwim- 
ming nimbler then I had hitherto feen. The biggeft fort 
were numerous, and as they moved, bent themleives like 
G. The other forts of Animals were in great numbers, 
infomuch that tho themeal were little, yet the water it 
was mixt with leem'd to be all alive, there were alfo the 
long threads above mentioned.
