Little wonder that in less than two days, Gil Blas tells us, the old canon was reduced to the last extremity, and soon after breathed his last, much to the regret of the physician, who declared it was because he had not lost blood enough, nor drank a sufficient quantity of water. The mercurial Gil Blas shortly after took service with this learned medico, and kept his books, which he declares might have been with great justice styled a register of the dead; for almost all the people whose names it contained died soon afterwards. But after being about a week with the physician, Gil Blas was seized with a cramp which he attributed to the quantity of the “universal dissolvent” he was compelled to imbibe, and had to consult his master. “Why, truly, Gil Blas, I am not at all surprised that thou dost not enjoy good health,” said the hydropathist. “Thou dost not drink enough, my friend. Water taken in small quantities serves only to disentangle the particles of the bile, and give them more activity, whereas they should be drowned in a copious dilution. I will warrant the consequence, and if thou wilt not take my word, Celsus himself shall be thy security.” It need hardly be wondered at that Gil Blas soon came to believe that he also had a natural talent for the medical profession, which was so easy to acquire and lucrative to practise, and was rapidly promoted as assistant to his master. “Listen, my child,” said the doctor one day, “I will immediately disclose to thee the whole extent of that salutary art which I have professed so many years. Know, my friend, all that is required is to bleed thy patients and make them drink warm water. This is the secret of curing all the distempers incident to man. I have nothing more to impart; thou knowest physic to the very bottom.” Thus the _ci-devant_ valet soon robed himself in a physician’s gown and long _perruque_, then went forth to practise, but resolved to drink wine every day, of which he said he drank huge draughts, and (no disparagement to the Roman oracle) “the more I filled my stomach, the less did that organ complain of the injury it received”. So he bled and watered the community. But the time soon came when this young practitioner met with a reverse. When called in to consultation with a Spanish doctor of another school, a dispute arose on the subject of the water-cure, which ended in a pitched battle being fought between the rival medicos over the unfortunate patient, and they were not separated until each had lost a handful of hair. This ended in the discharge of Gil Blas, who immediately took the opportunity of imbibing a considerable quantity of wine at the first tavern he came across, and returned to his patron in a condition of considerable elevation. The wine having made him thirsty, he consumed a large quantity of water while telling his story.
