This is improperly called by some the scorbutic rheumatism, and may generally be distinguished by the patient's urine; for a kind of filaments or threads may be seen to float in it, which are not quite so transparent as the urine it-self, but when taken out they will appear as pellucid as crystal, will rope to a great length, and when dry'd will turn white. This is the morbific matter of the gravel, gout, hip-gout, and all such kind of pains distinct from the rheumatism. To cure this disorder, nothing is more certain than Spanish soap; of which, from half an ounce to an ounce must be taken in a day for a month together.
