Strings, whereof there were about a thourand in one Hak 
Kjore or fewer , according to the thicknefs of the Hair 
Whether thefe Strings are hollo W3 ie. fo iiiany Pipes or Vef- 
fels , I cannot poficively fay 5 but it feemeth tome that they 
are. So that I conceive we may not unfitly compare the 
Clods of the Hair (coafifting of the aforefaid irregular 
particles) to the Bark of a Tree 5 and the little firings 
which compofe all that part of the Hair within the Clods, to 
the Pipes which make the Wood. 
Thefe Strings , or if you pleafe^ Pipes^ do noc lie every 
where ftretched out in a fl:raight line,butin fome places are 
feme what crooked , as at 
I have alfo fliewed feveral Gentlemen the Brisflesofa 
Hogs and therein (being cut over thwart with a (harp 
knife) thefaid Strings, very diftinftly : which likewife 
feeraed to be hollow.

commonly fold their Claries at the rate ofa Pifto! (i,e, about 
1 7 fhillings and fix p^ence ) the foot. But if any Glafshath
