509&#93; J A Y Indies. It is generally occasioned bV sudden colds; wounds of the nerves, and nervous parts of the body, however slight; drawing of the teeth, and ailivtions of the gullet or wind -pipe. — Suppression of the erysipelas or rosej hysterics, rheumatism, worms, and the bite of venomous serpents] are among the many causes of this dangerous disorder. Opiates administered in large doses have, in some eases, been successfully employed ; though the vame medicine will also produce this malady. The warm bath, elec- tricity, the' free use of musk, oil of amber, and asn-fcetida, together with amputation of die wounded part, if there be the least symptom tff mortification, have all been found of occasional service. In hot cli- mates, Dr. Lind recommends im- mersion in cold water ; and in the first volume of the Trar/shclions of the American Philosophical So- fief!/, M. Tallmaxn advises af- fusion of cold water on the body of the afflicted. During the con- tinuance of this spasmodic disease, the patient can only receive sus- tenance through his teeth, cr by means of nutritive clysters. His food ought, therefore, to consist of the most nourishing broths and jel- lies : thus, by the judicious ap- plication of die different remedies above stated, and by carefully avoid- ing to take cold, the locked jaw may probably be restored to its former situation, in the course of a few days. JAY, or CofvUs glundariu*, L. a well-known British bird, remarka- ble for its beauty. It is about 1 3 Inches in length ; its forehead is white, streaked with black ; the head is covered with a tuft of long feathers, which the bird ere&s- at ICE [509 pleasure into the farm of a crest ■ the whole neck, back, bl bellv, are of a faint purple colour, intermixed v. it 1 1 jays build chiefly in woods, v. here ihey construct, their nests with sticks, fibres of roots, and tender twigs, in u Inch the females deposit from five to six eggg f a dark olive colour. They feed on acorns, as well as every kind of grain, and are very mischievous, frequently destroying young chick- ens and eggs : nor do they spare birds that have been caught in ;i trap, or entangled in bird-lime. — The most effectual method of tak- ing them is that already pointed out in the article JaCK-Haw. ICE, a solid, transparent, and brittle body, formed Of some fluid matter by the power of cold, or, more properly speaking, by the ab- straction of heat. Ice concretes generally on the surface of water j but tills effecl frequently varies under different circumstances. Jn the northern parts of Europe, there are three species of ice : 1. That wfricl formed on the sui - face. 2. An< ther kind, which congeals in the middle of the water, and beats' some resemblance to small hail ; and, 3. Ground-ice, that is pro- duced at the bottom; especialh- where it meets with any fibrotss substance to which it may adhere. The. last species is full of irregular cells ; and, on account of its infe- rior specific gravity, it produces many singular etiects, by bringing up heavy bodies from the bottom ot the water in which it is formed The ice that concretes in the mid- dle of the water, rises to the top' where it unites into large masses the formation, however, both of thi>. and of the ^rmmd-iic) takes plac -
