the Herbs had not duly fermented > which proceeded, in my 
apprehen(ion,from fome commixture of EflTential oyl,which by 
reiterated reftifications is either feparated or tranfmuced. The 
fame happens in the Vinoas fpirits of fermented Vegetables,and 
in their fixed Salts. 
9. In the Diftillation of the putrified herbs,the Urinous Spi- 
rits and fait came chiefly at the latter end with the Oyl, in the 
form of a thick white cloud or fumes, and condenfing in theJRe- 
cipient, formed an innumerable company of very irregular 
crooked rivolets,exadtly af er the manner of HartS'horci,Blood, 
&c; and at the beginning came the Phlegme with moftof the 
^f^/^;^ in great drops with little fume, and the rivolets ftrair, 
and without Jlria and wandrings. 
10. Some herbs, as Winter-favory, Sage,&c. inthefirft di- 
ftiilation yielded copioufly a Volatil Salt in a dry form, which 
did coat the Receiver,and fublimed into the neck of theRetort: 
So doth Tobacco ; zndonce Saffron did fo, indigeftion with 
fpiric of wine. 
I r. All plants,thus fermeuted,yielded plentifully fefpecial- 
ly toward the latter end of the diltillation,) a fa^tid grofs oyl, 
which, if the herb was well putrified, did not in theleaftre- 
femble the plant which produced it ^ and I could hardly per- 
ceive^that they differed from each other in either tart or fiiiell : 
only, if the plant was not throughly fermented, an Oyl would 
come over at the beginning of the diftillation,which,as alfo the 
water, would retain exaftly (he taft and fmell of the vegetable, 
which afforded it 5 and it would be fluid and tranfparent, like 
other Effential oyls.The Oylof herbs very well putrified came 
over chiefly at laji^ and did require a very ftrong fire to extri- 
cate it out of the herb;was moftly,efpecially that which comes 
Jafl: of al],of the colour and confidence of Tar, very tenacious, 
and did far and wide emit a very odd, faint, fetid, offenfive 
odour : If any thing became infefled by this oyl, it was not to 
be freed from it in a long time. 
12. Herbs,which,diftilledinanA'embic with water, yield 
little Eflentialoyl,asBaume,Mint, Camomil, &c, afford much 
of ir,thus fermented : And thofe, that give much Effential oyl, 
as Wormwood with many others being putrified, yield abun- 
dantly more. ,
