A branch from the fifth pair of nerves is spread on the membrane that lines the nostrils, and another branch from the same passes through the foramen su-percih, and spreads on the teguments of the forehead; hence, when pain is in the eyeball and forehead, a heat is perceived in the nostrils; and benefit may be expected from external means, if applied to the mem-brana narium and to the forehead: alternate pressure near the superciliary holes of the frontal bones will also relieve.

Cephalalgia spasmodica. The sick headach. Though this afflictive malady scarcely differs from the symptomatic headach, arising from the stomach, yet, from respect to Dr. Fothergill, who first called our attention to it, we shall speak more particularly on the subject. He observes, that it is not the complaint of any particular age, sex, constitution, or season, but it is incident to all. The sedentary, inactive, relaxed, and incautious respecting diet, are the most exposed to it.

The patients, he observes, generally awake early in the morning with a headach, which seldom affects the whole head, but one particular part of it, most commonly the forehead; over one frequently, sometimes over both eyes. It is occasionally fixed about the upper part of the parietal bone, of one side only; sometimes the occiput is the part affected; or it darts from one place to another. From the time it commences until it wholly ceases, it is in different degrees. With this is joined more or less of sickness, which in some is scarcely sufficient, without assistance, to provoke vomiting, though in others this operation is easily excited, If this pain happens, as is most common, early in the morning, before any meal is taken, then phlegm only is thrown up, unless the straining be severe, when some bile follows. In this case the disease soon begins to abate, leaving a soreness about the head, a squeam-ishness at the stomach, and a general uneasiness, which induces the patient to wish for repose. Perhaps, after a short sleep, he recovers perfectly, debilitated only by his sufferings. The duration of this conflict differs in different persons; in some it goes off in two or three hours; in others it continues twenty-four hours or longer, and with a violence scarcely to be endured, when the least light or noise produces most excruciating pain. In young persons it most commonly goes off soon; if it continues to harass them many years, as it sometimes happens, the fit is of longer duration, and leaves the whole system in so weak a condition as is not soon recovered. Its returns are very irregular; some suffer from it every two or three days, some in two or three weeks, others in as many months, or yet more seldom. Those who use but a little exercise, and are inattentive to their diet, are the greatest sufferers; costive habits arc the most exposed to it; and habitual laxity of the bowels coming on has removed this complaint.

The disease is spasmodic; it attacks after digestion is performed, when the bile is supposed to have acquired its full activity, undiluted by fresh supplies of liquid: from numerous circumstances it appears to proceed from the stomach. For the most part it proceeds from inattention to diet, either in respect to kind or quantity, or both; and without exact conformity to rule in this respect, medicine proves ineffectual. Butter, pepper, or other spices, meat pics, rich baked puddings, drinking strong liquors, with a very free use of malt liquors, are supposed to produce it. Quantity as well as quality of diet is to be considered. Bile, if very acrid or bitter, is a frequent cause, unless in habits where the bile will purge, and these are rarely affected by this disease.

An emetic, or mild cathartic, and some time after it an anodyne, will carry off the complaint; but, as we have said, the fits will return after irregular and uncertain intervals. If disposed to costiveness, the belly should be kept open, by a regularly repeated laxative; and rhubarb, or aloes, is preferable to the saline purgatives. If acid abounds in the stomach, small doses of stomach bitters, with a little alkaline salt, or a chalybeate, once or twice a day, may be given; but in general, soap and pil. aloes cum myrrha, or magnesia and rhubarb, in small doses, daily continued, will often prove effectual. The following eccoprotic is highly useful: aloes succotorin. 3i. rati- rhab. et radi.

This disease is not the effect of any sudden and accidental cause, but of reiterated errors in diet, or in conduct, which, by weakening the organs of digestion, and otherwise disordering the animal functions, occasion frequent accumulations of indigested matter, and require a steady perseverance in the use of medicines. This change cannot be effected speedily; a patient observance of proper regimen, in respect both to medicine and diet, is necessary. The former ought, therefore, to be so contrived as to be taken without disgust for several weeks together, and to be repeated at proper distances, till the digestion is rightly performed, and the bile properly secreted and discharged. Unless the whole plan of diet, both in kind and quantity, accord with medical prescription, the benefits will be proportionally diminished. It demands attention to observe the just medium, and no less resolution to keep steadily to the directions enjoined, particularly in respect to quantity. This must vary in different constitutions; but the first sensation of satiety is the surest proof of the meal having attained its proper limits. These patients are often subject to false appetite, a craving that does not arise from the demands of health, but from the morbid irritability of the stomach, which prompts them to eat more, and more frequently than nature requires, by which their sufferings are increased, and the disease gains ground.
