This is so called, because when the patient has a fit, he falls suddenly on the ground. When it gives warning of its coming, it may be known by a weariness of the whole body, unquiet sleep, unusual dread, dimness of fight, or a noise in the ears. In some there is a sense of cold air arising from the lower part of the brain. The fits are longer or shorter, according to the different causes; some return on certain days, hours, and even months; some at the new or full moon, or both. In women often at the time of their monthly evacuations: sometimes the passions of the mind will bring on a fit, e-specially a sudden fright. This disease generally ends of itself in boys when they are fit for marriage, in girls when their monthly evacuations begin to appear. Sometimes change of place, diet, and the way of living, will put an end to the falling sickness.

To perform a cure, blisters may be laid to the back part of the head, a little before the fit is expected, and then "Take "forty grains of valerian-root, and twenty grains of cinnabar; "make them into a powder." This is one dose, and must be taken morning and evening, for three or four months. Or, rather, "Take of the peruvian bark one ounce, of valerian-"root a quarter of an ounce, and make them into an elec-"tuary with syrup of orange-peel." The dose is a dram, morning and night, for three or four months, and afterwards, two or three days before the full and change of the moon : but if two drams of Virginian snake-root be added to the above electuary, it will make it still better. Some recommend an ounce of misletoe with a dram of assa foetida, made into a powder; the dose is half a dram every sixth hour, drinking a draught of a strong infusion of the same plant after each dose. "When a patient is so happy as to foresee the fit coming on, let the feet and legs be rubbed strongly with a coarse cloth, which may prevent it.

But, after all, there is nothing better than ten grains of musk, taken twice a day; unless a medicine lately discovered, and which may be had at Mr. Newbery's in St. Paul's Church-yard, London. It has been used in some of the London Hospitals, with great success, in the cure of this obstinate disease, and has succeeded when other remedies have failed, and perhaps is the very heft hitherto sound out for this purpose. I have been witness to its efficacy in some cases of this kind myself.

Intermitting Fevers Or Agues, are of several sorts: sometimes they come every day, and then they are called quotidian; sometimes every other day, and then they are tertian; sometimes there are two days between each fit, and then they are quartan or third day agues. An ague generally begins with coldness, shivering and shaking, which is the cold fit, after which the hot or burning fit takes place, which is succeeded with a sweating, at which time the ague is over till the next return: the length of these fits differ very much, especially when they are epidemical or common, and sometimes there is scarcely any cold fit at all, at others the hot fit is scarcely perceptable. Spring agues may be generally cured with the bark alone, which you must begin to give as soon as the fit is off, and not before: half a dram is a dose, and six of these doses must be given in twenty four hours, till the fit returns, turns, which it seldom does; however, some give a vomit before they will venture on the bark. To prevent a return, it will be proper to repeat the bark every eight or ten days, for three several times; it may be taken in red wine, or made up into an electuary with syrup of lemons. Those agues that happen after the end of the summer, are generally pretty obsti-nate, and then it will be necessary to add two drams and a half of Virginian snake-root to the electuary. When the countenance is yellow, the belly hard, and the body costive, it will be necessary to give the following electuary before the bark : "Take of Castile soap an ounce, species of hiera picra and "steel in filings, of each forty grains, of syrup of orange-"peel a sufficient quantity to make an electuary." The dose is half a dram, four times a day. Sometimes agues that will not yield to the bark, may be cured by the following powder: "Take twenty grains of the powder of camomile-flowers, ten "grains of diaphoretic antimony, and the same quantity of "salt of tartar; make them into a bolus with syrup of cloves:" it may be repeated every three hours.
