Rh in the incipient stages of those chronic disorders, which are attended with great debility; in chlorosis; and numerous other complaints incident to the female sex. The dose varies at each time, from half to three quarters of a pint, according to the age, constitution, and case of the patient: it is taken at two or three intervals, between 8 o'clock in the morning and noon. As this water is apt to produce a sensation of coldness in the stomach, together with nausea or sickness, when drunk fresh from the well, it will be advisable to pour it into a bottle; and, after closing it carefully with a cork, to immerse the vessel in hot water, where it will acquire a moderate warmth; and thus such inconvenience may be easily obviated. Sometimes, however, this chalybeate occasions pain in the region of the heart; a slight degree of giddiness; and a sense of fulness over the whole body; but these symptoms generally disappear in a few days after commencing a regular course; when it produces effects totally different, by increasing both the appetite, and the circulation of the blood, while the animal spirits are said to be improved.

There are many chalybeate springs in England, possessing similar properties with the Tunbridge-waters; but which our limits will not permit us to specify: we shall therefore only notice the Islington, or New Tunbridge Spa, in the vicinity of the metropolis. It is of a ferruginous taste; and, when first drunk, occasions a slight degree of vertigo, and a propensity to sleep, in persons of plethoric habits; but such symptoms may be prevented, by adding a small portion of pure water. Farther, the Islington chalybeate parts with its volatile ingredients within two hours after it is drawn: it will, therefore, be advisable to drink this fluid, if possible, on the spot; or, where such method is impracticable, to adopt the expedient before suggested by Dr. .—The New Tunbridge Spa may be safely resorted to by persons labouring under the complaints before mentioned, especially in scrophulous, and other glandular obstructions; as likewise with the view of reducing .

This solution possesses, though in a weaker degree, similar properties to those of the Islington Spa.  TUNNY, or Scomber Thunnus, a fish of the mackerel kind, which abounds in the Mediterranean Sea, and sometimes frequents the British coasts: during the season, considerable shoals are found in the lochs or lakes of Scotland, whither they resort in pursuit of that fish. The tunny is from six to ten feet in length; its round body is bulky; and the tail forms a crescent.

These fish are taken either with nets, or by hooks appended to ropes, and baited with herrings. In a fresh state, their flesh resembles raw beef: when boiled, it becomes pale, and acquires a delicate flavour, similar to that of salmon. The belly, however, is the part held in the greatest esteem, and which is mostly salted; but, being extremely fat, it ought not
