"For the object of the treatment, in these cases, is not to remove, but to avert the inflammation, and which, from the strong disposition to it, conferred by the organic disease, can only be effected by avoiding, not merely the causes of inflammation, but likewise, all those agents, which are calculated, in any way, to increase the momentum of the circulation." "Beyond those, the common precautions against morbid irritations, little else can be done." When the turgescent state of the brain, arises from a disturbance in the digestive organs, it will be remedied, by means directed to this cause. Our author locates the primary seat of this disturbance, in most cases, in the liver; though he admits, it may occasionally be in the stomach and intestines. He places great reliance for correcting and increasing the secretion of bile, on small doses of calomel,--purging off the contents of the intestines by aperient medicines; and recommends, at the same time, the application of cups and leeches to the temples, as a measure of precaution. He very properly lays considerable stress on the necessity of combating this secondary affection of the head; "For though the means applied, to correct the disorder in the digestive organs, may be sufficient to remove the turgescent state of the brain, which arose from it, yet, those means will have little or no control over the excitement, which that turgescent state has created; and still less can they avail in subduing an excitement, that may even survive its remote cause, and continue independently of it. By overlooking these facts, much distrust and disappointment have arisen with many, who confided in the opinion, delivered by some writers, of the uniform prevalency of chylopoietic disturbance, as a cause of this disease, and of the sufficiency of calomel to remove it." When the inflammation exists, and is a sequel of some pre-existing structural disease in the brain or membranes, all that can be reasonably expected, is to _palliate_ it by the antiphlogistic plan; but when it is idiopathic it may readily be cured, by the same remedies, graduated to the age and strength of the patient and to the violence of the attack. Dr. A. seems to rely principally on cups and leeches;--not excluding, in some cases, bleeding from the arm. Blisters to the summit of the head and afterwards a cold evaporating lotion to the temples, are also recommended. As soon as, by these means, an impression is made on the disease, mild diaphoretic medicines, assisted by the tepid bath, or the pediluvium, maybe prescribed;--the bowels are to be kept open by small doses of calomel, followed after two hours by a draught of some aperient medicine,--the antiphlogistic regimen should be rigidly enforced, and light and noise carefully excluded.
