When the purging is considerable, five grains of the hydrargyrum cum cretâ, with five of the pulvis ipecacuanhæ compositus, given every night or every night and morning, often checks it; if this remedy fail, a stronger opiate may be exhibited, and sometimes an anodyne enema may be administered with great advantage. If there be constipation, one or two drachms of castor oil is the proper laxative. Active or irritating purgatives are highly injurious. When blood is mixed with the stools or there is considerable hæmorrhage from the intestines, every thing that can irritate the mucous membrane must be carefully avoided. The mineral acids sometimes appear to check the discharge. The infusion of roses rendered stronger by the addition of a few drops of the sulphuric acid, is a convenient mode of administering such medicines, and the efficacy of the draught is sometimes improved by the addition of a drachm of the tincture of hyosciamus. It is not uncommon for copious discharges of blood to alternate with constipation. In this case the mildest laxative must be administered with caution. The powers of life are sometimes so prostrate, that three or four stools, excited by purgative medicines, are sufficient to exhaust them. A tea-spoonful of castor oil, repeated at intervals of six hours, is all that should be attempted. Now and then a stimulant has a greater effect in checking the hæmorrhage than an astringent, and then the oleum terebinthinæ is the best remedy. IV. We have spoken of a fever still more intense even than this, severe as it is, under the name of the intensest form of fever. And of this, the same may be said as was stated of the mildest, that there is little or nothing to be done. As far as regards the treatment, the two extremes of fever, the mildest and the most intense, meet, for in the first no remedies are required, and in the second, none are of any avail. In these latter cases, there is no remedy and no combination of remedies yet known, capable of affording effectual aid. The abstraction of the smallest quantity of blood is fatal: the application of the cold bath is out of the question; the warm bath is inert; the vapour-bath affords rather more prospect of benefit; but the proper remedies, if any exist, remain to be discovered. When a person has swallowed a certain quantity of laudanum, there are remedies which are capable of counteracting the poison and of saving the patient. When he has swallowed a larger dose, provided it amount to a certain quantity, no remedies will avail, excepting the application of the stomach-pump. Unless the poison be promptly expelled from the system, adopt with the utmost vigour the best-concerted expedients which the medical art can supply, the patient will die. A person afflicted with the intensest form of fever, is in the condition of a person who has swallowed this large dose of poison. When a pump is invented, capable of extracting _his_ poison from the brain, he may be saved.
