416 VARIOUS STRENGTH O F, See.
Enough, it may, perhaps, bethought more than enough, has
been faid, to fhew, that the ftrength of lime-water is very different*
according to the different quantities of water poured on quick-lime.
However, I muft be allowed to fay, that this point, which has been
difputed by my good friend, is of that confequence as to deferve
to be fully cleared up ; fince, to fuch as drink lime-water, with a
view to the cure of the ftone, it is of no fmall importance to know*
how it may be prepared fo as to have the fureft and fpeedieft ef¬
fects. And as lime-water, injected into the bladder, will undoubt¬
edly diffolve a ftone lodged there y it is evident, that, after the blad¬
der has been accuftomed to the weaker lime-waters, or to thofe even
foftened with a little fweet milk, the diffolution of the ftone may *
be much haftened, by injeéting fuch as are more itrongly impreg¬
nated with the virtues of the lime.
With regard to the lithontriptic powers of oifler-fhell and ft one-
lime water, I fhall only fay, that, as in a variety of experiments made
during the courfe of ten years, I had always obferved the fuperior
efficacy of the oifter-lime water, I thought it to no purpofe to make
a new trial : any one who doubts on which fide the truth is, may
eafily fatisfy himfelf. But, in making the experiment, the calculi
ffiould either be immerfed in a large quantity of lime-water, or elfe
it fhould be renewed upon them every three or four days«.
