ftals } it feem’d to follow as a natural Confequence, that 
this Metal is the Subjed on which the Lixivium of 
Blood produces the change * and this Thought gave oc- 
cafion to the following Experiments on metallick Ba- 
dies, in order to obferve if the fame Change of Colour 
could be produc’d in any of them. 
To a Solution of Silver in Aquafortis was pour’d 
the Lixivium of Blood, which occafion’d a Coagulum 
of a pure Flefh Colour. The Lixivium made with 
Flefh produc’d a whitifh Coagulum , and the 01. Tar- 
tars (which was continued to be us’d by way of corn- 
par ifon with the other Lixivia') a much whiter. By 
the Addition of the Spirit us Sal is to each of thefe, the 
Bloom of the Flefh Colour was taken off in the firft, 
but fuffer’d no other Change. In the fecond the Co- 
agulum was a little ting’d with Blue} and in the third 
the White was manifeflly improv’d. The bluifh Tinge 
in the fecond of thefe Experiments cannot entirely be 
afftgned as the Effed of the Lixivium with Flefh, be- 
caufe Silver, when thus diffolv’d, whether precipitated 
with Salt Water, or 01. Tartari , will, after it has flood 
fomeTime, contrad a bluifh Tinge, and this from an 
Alloy of Copper, from which it is not entirely freed. 
The fame Liquors were made ufe of to precipitate 
the Mercury in the Mercurius Sublimatus Corr. dif- 
folv’d in Water } the Confequence of which was, that the 
Lixivium with Blood produced a pure yellow } the 
Lixivium with Flefh an Orange Colour} and the 01. 
Tartari a dingy red. The addition of the Spiritus 
Salis to thefe, made fome very odd Alterations * 5 for the 
firfl chang’d its yellow Colour for an Orange } the fe- 
cond, its Orange for a Blue } and the third became 
quite clear again without any Colour. The blue Co- 
lour in the Mixture of the Lixivium with Flefh, and 
Solution of Sublimate, may be accounted for from the 
3. Vitriol
