V. Further Experiments on Sub fiances ref fl-

the Means of hafl eiring and promoting it \ by

.fofl</Nov.i$,Tr TAVING given a particular Account 
‘/3 0 - of the Manner of trying Antifeptics 
on the fibrous Parts of Animals *, I fhall only mention 
the Refult of fome Experiments made with them 
upon the Humours. 
1. Deco&ions of Wormwood and of the Bark, 
alfo Infufions of Chamomile-flowers, and of Snake- 
root preferved Yolks of Eggs, not only feveral Days 
longer than Water did alone, but alfo when a good 
Quantity of Sea-Salt was added to it. I likewife 
found that Salt of Hartfhorn preferved this Subftance 
better than four times its Weight of Sea-Salt. 
2 . Ox’s Gall was kept fome time from Putrefac- 
tion by fmall Quantities of Lye of Tartar, Spirit of 
Hartfhorn, crude Sal Ammoniac , and the faline Mix- 
ture, and ftill longer by a Decodion of Wormwood, 
Infufions of Camomile-flowers, and of Snake-root ; 
by Solutions of Myrrh, Camphire, and Salt of Am- 
ber : All were feparately mixed with Gall, and found 
more antifeptic than Sea-Salt; and feemingly in pro- 
portion to their Effeds upon Flefh. Only Nitre 
failed; which, tho’ four times ftronger than Sea-Salt 
in keeping Plefh fweet, is inferior to it in preferring 
Gall ; and remarkably weaker than crude Sal Am * 
maniac, which again is fomewhat lefs powerful 
than
