_Water-casting._ The fanciful notion of recognizing diseases by the mere inspection of the urine was denounced years ago, by an old statute of the College of Physicians, as belonging to tricksters and impostors, and any member of the college was forbidden to give advice by this so-called "water-casting" without he also saw the patient. The statute of the college runs as follows: "Statuimus, et ordinamus, ut nemo, sive socius, sive candidatus, sive permissus consilii quidquam impertiat veteratoriis, et impostoribus, super urinarum nuda inspectione, nisi simul ad ægrum vocetur, ut ibidem, pro re natû, idonea medicamenta ab honesto aliquo pharmacopoea componenda præscribat." An allusion to this vulgar error occurs in the "Two Gentlemen of Verona" (ii. 1), where, after Speed has given to Valentine his amusing description of a lover, in which, among other signs, are "to walk alone, like one that had the pestilence," and "to fast, like one that takes diet," the following quibble takes place upon the within and the without of the symptoms:
"_Valentine._ Are all these things perceived in me?
_Speed._ They are all perceived without ye.
_Speed._ Without you? nay, that's certain; for, without you were so simple, none else would: but you are so without these follies, that these follies are within you, and shine through you like the water in an urinal, that not an eye that sees you but is a physician to comment on your malady."
This singular pretence, says Dr. Bucknill,[638] is "alleged to have arisen, like the barber surgery, from the ecclesiastical interdicts upon the medical vocations of the clergy. Priests and monks, being unable to visit their former patients, are said first to have resorted to the expedient of divining the malady, and directing the treatment upon simple inspection of the urine. However this may be, the practice is of very ancient date." Numerous references to this piece of medical quackery occur in many of our old writers, most of whom condemn it in very strong terms. Thus Forestus, in his "Medical Politics," speaks of it as being, in his opinion, a practice altogether evil, and expresses an earnest desire that medical men would combine to repress it. Shakespeare gives a further allusion to it in the passage where he makes Macbeth (v. 3) say:
