Harrogate water is used in va- rious disorders of the alimentary canal, and in those affections of the biliary system from which the former are generated. Its chief internal use, however, is in scro- phulous and cutaneous disorders ; though it is also of Considerable service, when applied externally to leprous eruptions, and other ob- stinate diseases of the skin. It is tiki u ise a safe, and often a power- ful remedy for the piles, as well as against die round worm, and ascarides, if such a quantity be drunk as will prove a brisk purga- tive. In general, such draughts are taken as will produce a sensible effect on the bowels : for this pur- pose, three or four glasses, con- taining somewhat more than half a pint each, should be swallowed in the morning, at moderate inter- vals. The water ought to be used cold and fresh from the spring, if the stomach can support it. In order to corn et the riaaseous fla- vour, Dr. Garnett judiciously advises patients to cat a small por- tion of sea-biscuit, ox coarse bread, instead of taking aromatic seeds, sugar-comfits, &c. By the for- mer expedient, the offensive ta^te will be speedily removed, and the stomach not be cloyed ; a circum- stance of the first consequence to invalids. HARROW, an implement of agriculture, commonly used for T, ' • ' with earth. There i-, . , an- other obj iportance, hi< h it ma beappli* d to pul I previously to its receivin ; the seed. union harrows are of differ- ent forms. The first we shall no-

Tire second has three bulls, provided with twelve similar teeth : a third has four bulls, and twenty teeth, com- posed generally of iron, which are ten, cloven, or twelve inchfes apart. The last n ■ ' . nt is erable to either of the former j as, on account of its iron teeth, it is better calculated for covering the seed : but it is still very impe ' and the use of it attended with manv inconveniencies. Hence d d harrows have been invented at rious periods, theprincipal ofjsvrflch we shall describe in the orde time. The earliest that men', notice is the Harrow-plough, invent the year ljffjfc, by a Air. Wood, of Cheimsfurd, Essex : a full a< i of which appears in the 2d vol. of the Museum Budticum et Cbmmerciale. It consists of a common harrow- frame, 7 feet in length, and 4 in breadth, to which are fitted 14 iron shares, of the form of a heart, with ;» rounded point, being hollowed un- derneath, and convex on the up- per surface : the edges of the rounded point, and two sides of these shares, are sharpened in the same manner as a common hoe ; and the shares are disposed in the following order ; the letter A re- presenting the front, and B the back of the frame. - A
