The Spittle of another old man and a good fellow 
was like the former, but the Animals in the fcurt upon 
the teeth, were not all killed by the parties continual 
drinking Brandy , Wine, and Tobacco, for I found 
a few living Animals of the 3/3?. fort, and in the fcurf be- 
tween the Teeth I found many more fmall A nimals of 
the 2 imallefl forts. 
J took in my mouth fome very fliong wine-Vinegar, 
and clofing my Teeth, I gargled and rinfed them very 
well with the Vinegar, afterwards I wafht them very well 
with fair water, but there were an innumerable quant' ty 
o^ Animalsyet remaining in the icurf upon the Tceth,yet 
moft in that between the teeth, and very few Animals of 
the firft fort 4- 
I took a very little wine- Vinegar and mixt it with the 
water in-which the Icurf was diflblved, whereupon the A- 
nimals dyed prefently. From hence I conclude, that 
the Vinegar with which I waflit my Teeth, kiird only 
thofe Animals which were on the outfide of the fcurf, 
but did not pafs thro the whole fubftance of it. 
In many of my foregoing Obiervations, I faw fome 
clear fliining Particles, whereof fome were round, others 
fomewhat irregular , of feveral bignefTes, and the lar- 
geft about 2/ times the bulk of a blood-Globule, thefe 
if they had not funk in water, I fhould have taken for 
Particles of fat. 
The number of thefe Animals in the fcurf of a mans 
Teeth, are lo many that I believe they exceed the num- 
ber of Men in a kingdom. For upon the examination 
of a fmall parcel of it, no thicker than a Horfe-hair,. I 
found too many living Anima's therein, that I guefs 
there might have been 1000 in a quantity, of matter no 
bigger then the . part of a fand. 
A certain man being faid to have worms taken out of 
his face, I took a quantity of thefe imagined worms, 
which I laid upon a clean Glafs, that I might view them
