when the sap runs most, they pare off the bark of the pine, to make the sap 

 run down into a hole, dug at the bottom to receive it : as it runs, it leaves a 

 cream or crust behind it, which is tempered in water, and fraudulently sold for 

 white bees-wax, to make flambeaux of. Then they take up the juice in scoops 

 from the bottom, and having a good quantity, they strain it through a grocer's 

 basket, such as they put up Malaga raisins in ; that which runs easily through 

 is the common turpentine ; then they take that which remains above, and add- 

 ing a sufficient quantity of water, distil it in an alembic ; what is so distilled is 

 oil of turpentine, and the residuum that is left is conmion rosin. Afterwards they 

 cut the stock of the tree into large chips, and pile them hollow in a cave, cover- 

 ing it over the top with tiles, but so as to let some air come in to feed the fire ; 

 then burning them, there runs down a thick juice to the bottom, where they 

 may make a small hole for it to run out at, for a large hole would set it all in a 

 flame ; and that which so runs out is tar ; which tar being boiled gently over 

 again, to consume more of the moisture, becomes pitch when cold. 



Concerning a JVoman who voided the Bones of a Foetus above the Os Pubis, and 

 by other extraordinary Ways. N° 24 3, p. 292. 



Margaret Parry, of Kintbury in Berkshire, in 1668 was delivered of a child. 

 She continued indifferently well two or three days after her delivery ; then new 

 pains came upon her, and for three weeks together there came from her daily 

 some quantity of corruption, with pieces of flesh and skin ; and she continued 

 dangerously ill for about eight weeks, at the end of which time she was relieved, 

 as is supposed, by taking a potion which was prescribed her. After two years 

 she began to breed again, and had three children in the three years following 

 all which were drawn from her by violence. During her lying-in with the last 

 of these three children, some bones of a foetus came from her ; after this several 

 other bones came away witii her catamenia, and several, among which were 

 parts of the skull, and some of the larger bones of the body of a foetus, worked 

 their way by degrees through the flesh above the os pubis. 



The woman is now living, October l684j. and in health; all the children 

 were born perfect. 



On the Barometer and other Observables. By Dr. u4she, Lord Bishop of Cloy ne- 



N° 243, p. 293. 

 On the evening of March 3, 1687, we had much thunder ; and that and the 

 next day the mercury in the barometer was much lower than ever I observed it, 

 viz. only -v above 28 inches. — March 18th, I observed here the occuliation of
