was Twenty, and by that Confequence, Four Hundred 
fuch thin Roots together, were as thick as the Root out 
of which they all came forth. 
Now as 60 Diameters of the firft Root make out i 
Inch, and zo Diameters of the fecond Root make i of 
the former, it follows, by the Rule of Geometry, that 
3600 of the firft Roots make i Inch. 
Thefe 3600 being multiplied with 400, there comes 
out the Number 1 4400^0 of thin Roots, which toge- 
ther, make up the thicknefi of i Inch*

invifible to our Eyes, almoft all of them are broken^ 
off, becaufe they are always incloftd with wet Earth or 
Sand. 
After thefe thin Roots, which were come forth, had: 
been in the Glafi for Three or Four Days, without

the Tooth out of the Flefli, and thus to get rid of the 
Tooth, likewife it did fucceed, becaufe the Tooth was 
left faft only by a little Part to the Flelh, which I could
