HOUSE-LEEK, or Sempervi- vum, L. a genus of perennial plants, consisting of 13 species, one of which, the Sempervicum te.il.orum, Common House-leek, or Cyphel, is a nadve of Britain ; it grows on the roofs of houses and old walls, where it flowers in the month of July. This plant is eaten by sheep and ^oats : its juice, when mixed with honey, is said to be of considerable hervice in aphdioUs cases, or the thrush of children ; it also affords immediate relief, whether applied by itself, or mixed with cream, in burns and other external inflam- mations.

HUNGEll, an uneasy sensation, occasioned by long abstinence from food, when the body is in a state of perfect health. Without attempting to specify the different preparations used by the ancients, for the prevention of hunger, we shall merely commu- nicate such substitutes as have been judiciously recommended on sudden emergencies ; together with ibo most proper means of adminis- tering food to persons who have for a considerable time been deprived of aliment.

It is, however, a matter of serious consequence to such as are exposed to this dreadful calamity, to be provided with the means of alie- nating its horrors, when about to undertake a long journey, in which they are apprehensive of a scarcity of provisions. The American Indians are sup- pose- 1 to use a -preparation consist- ing of the juice of tobacco, and the shells of oysters, snails, or cockles, burnt so as to be reduced to the finest powder. These ingredients are dried, and formed into lozenges of a proper size to beheld between the gum and the lip, so that, being gradually dissolved, they obtund or mitigate the sensations bodi of hunger and thirst. A more palatable and efficacious substitute for food, however, in a famishing situation at sea, is the , powder of salep, .which has been judiciously suggested by Dr. Lixd, in order that it may form part of the provisions of every ship's com- pany. This powder, together with portailc soup, when dissolved in boiling water, forms a rich thick jelly, and one ounce of each article will furnish a whole day's subsist- ence for an adult. Indeed, from die experiments made on salep, by Dr. Perc'ivax, it appears to con- tain a larger quantity of nutritious aliment, 1:1 proportion to its bulk,. than any other vegetable matter hidierto known as food. It also possesses diealuable property of suppressing the nauseous taste of salt water ; and may thus be of great utility at sea, when fresh v, aler is tidier s holly, or so far con-. smucd,
