NERVOUS DISORDERS. 6j3 medies which are möft likely to leflen or remove thefe feveraî cawfes. & r ï. Some morbid matter in the blood. (a) As we are often ignorant of the nature of that matter in the blood which is the caufe of nervous diforders, fo we mud be often at a lofs how to correct or expel it. When I fufpeft it to be of that kind which produces the arthritis vaga, from knowing the family- didemper of the patient, his conditution, and manner of life, or his being much troubled with flying pains in his head, arms, or limbs, I rely mod upon a proper diet and exercife, with the tincdure of the bark and bitters mentioned under the fird intention of cure, in order to prevent the generation of this matter, or gradually to fubdue and carry it off, when already generated.

When the patients are liable to fits of the true gout, I increafe the proportion of the rad. gentian.. and eort. aurant. in the tindlure, adding at the fame time fome nutmeg or ginger, efpecially if the domach be cold and flatulent. In this cafe alfo, the tincture may be taken to the quantity of two table-fpoonfuls twice a-day. I
