52. I infufed p#/v. gr. x. in oider lime-water, une. iii. for 
twelve hoursafter which I immerfed in it a piece of B, fix grains 
in thirty-two hours warm digedion, near two grains of it were 
rotten and diffolved. 
It is obfervable that lime-water, mixed with powder of rhubarbr 
immediately acquires a deep red colour, as if cochineal had been 
infufed in it ; and the fame thing happens when an infufion of 
rhubarb is mixed with dale urine or potalh ; whence we may fee 
why the urine of a perfon who has taken rhubarb acquires a bloody 
colour, if it remains but ever fo fhort a time in a pot, which is 
crufted with fèdiment of dale urine. A phenomenon which has at: 
fird given uneafinefs to. not a few who were ignorant of its true 
caufie. 
53. Having infufed in the fame manner pulv. jalap, gr. x. in 
©ider lime-water, une. iL I put in a fragment of B, fix grains, which* 
by digeding warm thirty-two hours, was reduced to five grains. 
54. A piece of B, four grains and a half, being for thirty-four 
hours digeded warm,, in an infufion of fenna drach. fern, in oider 
lime-water, une. iii. lod one grain., 
55. Having diffolved manna, ferup. it, in oifter lime-water, une. ii. 
I immerfed in it a piece of B, four grains and a half ; which, by be¬ 
ing kept thirty-four hours in a moderate heat, had above a grain 
of its fubdanee rotten and, diffolved. 
From thefe experiments we fee, that i£ by drinking lime-water, 
the body fhould be rendered codive, which (efpecially if no foap is. 
taken along with it) may be often the cafe, it will be better to ufe 
fome of the lad mentioned purgatives, than any of the faits in. the 
beginning of this fe<dion0.
