the neighbouring parishes, for about seventy years: but it is not now nearly so frequent as it was about thirty years ago. The history of this singular affection is still extremely imperfect: and it is only from some of the medical practitioners in that part of the country where it prevails, that a complete description can be expected.” Our author has already noticed the convulsive disease prevalent in the Shetland Islands, and has quoted Hibbert’s account of it. The following, however, from a very valuable manuscript account of the Orkney and Shetland Islands, drawn up about 1774, by George Low, with notes, by Mr. Pennant, is given in the journal already cited, and will be read with interest. The facts were communicated to Mr. Low by the Rev. Wm. Archibald, parochial clergyman of Unst, the most northerly of the Shetlands. “There is a most shocking distemper, which has of late years prevailed very much, especially among young women, and was hardly known thirty or forty years ago. About that period only one person was subject to it. The inhabitants give it the name of convulsion fits; and indeed, in appearance it something resembles epilepsy. In its first rise, it began with a palpitation of the heart, of which they complained for a considerable time; it at length produced swooning fits, in which people seized with it would lie motionless upwards of an hour. At length, as the distemper gathered strength, when any violent passion seized, or on a sudden surprise, they would all at once fall down, toss their arms about, with their bodies, into many odd shapes, crying out all the while most dismally, throwing their heads about from side to side, with their eyes fixed and staring. At first this distemper obtained in a private way, with one female, but she being seized in a public way, at church, the disease was communicated to others; but, whether by the influence of _fear_ or _sympathy_, is not easy to determine. However this was, our public assemblies, especially at church, became greatly disturbed by their outcries. This distemper always prevails most violently during the summer time, in which season, for many years, we are hardly one sabbath free. In these few years past, it has not prevailed so extensively, and upon the whole, seems on the decline. One thing remarkable in this distemper is, that as soon as the fit is over, the persons affected with it are generally as lively and brisk as before; and if it happens at any of their public diversions, as soon as they revive, they mix with their companions, and continue their amusement as vigorously as if nothing had happened. Few men are troubled with this distemper, which seems more confined to women; but there are instances of its seizing men, and girls of six years of age. With respect to the nature of this disease, people who have made enquiry about it differ, but most imagine it hysterical; however, this seems not entirely the case, as men and children are subject to it;
