CHAPTER XIII.

Concerning the III Effects of Nutrimental Salt.
All salt used with food which has not been digested by the stomach, which also on being expelled has passed dcnvn into the intestine, unless it makes a thorough transit, generates colic and suffering in the bowels which are very difficult to cure. Its corrosive nature causes it sometimes to per- forate the intestines, as is shewn by anat€>my. If, however, it remains un- expeiled in the stomach, eructations and heartburns arise, with many other affections of the stomach. It sometimes happens, too, that the undigested Salt is coagulated in the mesaraic veins, forming a granular deposit, from which proceed many severe diseases which are little understood, and that not only in this particular part of the body but in others also, especially the urinary organs. Enough has been said on the different species of salts, their virtues and their faults. We now pass on to that salt which is more mineral in its character, and iis named Vitriol It excels all others by its utility, both in Alchemy and in Medicine.
