Cent you with an;aftQniftiing number of Veffels, wlikh 
appeared to me like Blood VefleJs. 
I would fain kao>v what food thefe Creatures live 
upon, befides Cheefe ^ in the firft place, becaufe I ne- 
ver yet faw em any where elfe but in Cheefe. 3 and in 
the next place, becaufe they cannot arife from Flefa^ 
for the Worms that fpring from the Eggs of Flies in 
Flefli, which we alfo call Mites or Fly-bow$, are fully 
grown in the fpace of nine days 5 but thofc v/hich 
feed upon Cheefe require a longer time for compleat- 
ing their growth, and Flefh will not keep fo long with- 
out Salting or Smoaking. * 
Since things ftand thus, we mjaft conclude that it is. 
always natural to thefe little Flies to lay their Eggs up- 
on fuch fubftances as will not eafily corrupt 3 now we 
may juftly reckon Cheefe to be fuch. 
Let's imagine that the Patient,whofeTooth threw out 
the Worms by Smoaking, had fome time before eaten 
Cheefe laden with young Worms, or Eggs of the a- 
bo ve- mentioned Flies, and that thefe Worms or Eggs 
were not touch'd or injur'd in the chewing of the 
Cheefe, but ftuck in the hollow. Teeth, and at laft in< 
finuated themfelves fo far into the fubftance of thiS- 
Teeth, that they gnaw'd the fenfible parts, and fo oc- 
cafiond the great pain. 
It appears . very ftrange to me, that fmoak in the 
Mouth or Tootli lliould have fuchaneiFeft, as to bring 
Worms out of ; hollow Teeth 5 for 1 cannot conceive 
how the little Worms fliould have a refpiration, to be 
fo far prejudiced by the Smoak, that they are obliged 
to come forth. 
To fatisfy my felf upon this point, I took a Glafs 
Ball, the Diameter whereof was almoft three inches, 
with a little hole in it as large as the thicknefs ot 
a Goofe Quill, hi this Glais I put ten Cheefe-wonns of 
the largeft fort, and twice or thrice tlirew in burning
