_Third Stage._--First, ice to allay the thirst, which is now, indeed, unquenchable; second, external heat; third, a continuation of the frictions; fourth, no opium, and, frequently, no brandy, especially among the children. MIXED TREATMENT--_First Stage._--Besides the above treatment, calomel and Dover's powders was a very frequent prescription; also scruple doses of calomel, and calomel and opium in small doses, and all with success. Nevertheless, I believe they occasionally did harm. _Second Stage._--First, blood-letting less frequent than above; second, calomel and Dover's powders continued; third, calomel and opium; fourth, calomel, capsicum and opium; fifth, soda powders; sixth, scruple doses of calomel every half hour; seventh, ice. _Third Stage._--Calomel and Dover's powder; calomel and opium; calomel, capsicum and opium; carbonate of ammonia and capsicum; scruple doses of calomel every half hour. External heat in various ways; ice, etc. Severe shocks of electricity along the course of the muscles to allay the cramps; also, the burning of alcohol on the skin. The first was the practice of Dr. Devan, the second, that of Dr. Gardner, and both lay claims to having been the first to use these means." The ointment alluded to above is composed of mercurial ointment, one pound, camphor finely pulverized, seven ounces, and the same quantity of capsicum. With this, the patient was rubbed briskly from head to foot and repeated at short intervals. The result was, that mercury generally showed its specific effects upon the gums in from five to ten hours from the commencement of reaction. The success of this external application of mercury, conjoined with its internal administration and frequent blood-letting, may be learned from the cholera statistics of this and other institutions. Dr. Pereira employed sixty-grain doses of calomel, it is said, with success, and Dr. Barton of New Orleans, in 1849, gave in ten cases from 120 to 150 and even to 180 grains of calomel at a dose, and, in one case, gave 220 grains, intending, it is said, to have weight sufficient to keep it down. This brave and heroic practice did not afford relief in a single instance; the cramps, and vomiting, and purging continued, and a few hours closed the scene--all died.
