THE VIRTUES OF LIME-WATER 
S E G T. VII. 
Experiments with lime- water and feveral fruitsy herbs, and roots^ 
THAT fucli a diet may be ordered for calculous patients as 
will leaft deftroy the. virtue of lime-water, after the experi¬ 
ments upon animal food, we fhall relate the eifeéls of different ve¬ 
getable fubftances upon it. 
36. I infufed a fragment of B, eight grains, in half an ounce of 
juice of flrawberries, and two ounces and a half of oilier lime-wa¬ 
ter 5 after four days warm digeflion, and feven days cold, it had 
loR none of its weight, nor was there any appearance of diffolutioix 
about it. 
37. I digefled a piece of B, fix grains, in half an ounce of juice 
of cherries and three ounces of oilier lime-water, fix days warm y 
but its, furface was neither foftened, nor its weight diminifhed, 
38. A fragment of B, fix grains, being put in a mixture of one 
ounce of a llrong decoflion of raifins and three ounces of oilier 
lime-water, was not any way changed by three days warm digeflion. 
From thefe experiments we may infer, that all fruits which 
have any acidity or lharpnefs, whether frelh, as goofeberries, flraw¬ 
berries, cherries, apples, pears, plumbs, peaches, &c. or dried, as 
raifins, prunes, currants, &c. ought to be abstained from by fuch 
as ufe lime-water with a view to the diffolution of the Hone. 
39. I infufed a fragment of B, five grains, in one ounce of a de- * 
coélion of afparagus and two ounces of oilier lime-water y in a few 
hours its furface began to turn white, and, in thirty-fix hours warm 
digeflion, it had thrown off, in white fcales, a full grain of its 
weight. As the grolfer parts of the afparagus fell always to the 
bottom of the glafs, it was neceffary to keep the calculus fufpended 
in the middle of the mixture, by means of a thread, otherways the 
diffolution does not fucceed quite fo well.
