than Nitre in preferving Flefh. The Nitre was Toon 
opened by the Gal), and emitted a vaft Quantity of 
Air, which rofe as from a fermenting Liquo- ; and 
when this happened, the Gall began to putrefy. 
But the faline Mixture generated no Air, and op- 
pofed the Putrefa&ion of Gall more than it did that 
of Flefh. 
3. The laft Trial was with the Serum of human 
Blood, which was preferved by a Deco&ion of the 
Bark, and an Infufion of Snake-root, nor with lefs 
Efficacy than Flefh. But Saffron and Camphire were 
not here above a fourth Part fo antifeptic as before j 
whether it be that they are lefs prefervative of this 
Humour, or, as I fufped, that they were not well 
mixed. Nitre a&ed nearly with its full Force, being 
about four times ftronger than Sea-Salt : It generated 
fome Air, but much lefs than it did with the Gall. 
No other Humour was tried j but, from thefe Spe- 
cimens added to the former Experiments, we may 
conclude, that whatever is prefervative of Flefh will 
be generally antifeptic, tho’ perhaps not always with 
equal Force. 
4. Having already {hewn how putrid Flefh might 
be fweetened, I fhall conclude this Part of my Sub- 
jed with a like Trial upon the Yolk of an Egg. A 
Portion of this, being diluted with Water, flood 
till it corrupted ; when a few Drops were put into 
a Phial with two Ounces of pure Water, and about 
twice as many Drops were mixed with a ftrong In- 
fufion of Camomile-flowers. At firft both Phials had 
fome Degree of a putrid Smell ; but being corked, 
and kept a few Days near a Fire, the Mixture with
