GENERAL information, To DETECT A DISLOCATED JOINT. OQ a joint is sprained, swelling comes gradually; when dislocated, immediately BILLING FOE OLD NAIL HOLES. ljaj following method of filling old nail ^rp81^ woodis not only simple but effectual: Wi. e. fine sawdust and mix into a thick Wli R^ae> poand it into the holes, and, tie en Ilry, it will make the wood as good as \Y, SLEEP. v "e amount of sleep requisite in a state of j. has been stated, by the best authority, a according to age, the following :—For „ from fifteen to twenty hours; from of five to twelve, twelve hours from of twelve to sixteen, ten hours from to 24, nine hours afterwards, seven Drs are sufficient. To DETECT ARSENIC IN WALL-PAPER. 411YOyae who suspects the presence of arsenic ,e'r wall-paper can put the accuracy of to the test in the following manner :—Dip a small pieoe of the ? Jet in strong ammonia water. If arsenic Oj, Pre*ent a bluish colour will appear. In 0* to make oertain doubly sure, a orystal a ^traure of silver can be moistened with a °P of this fluid. This further test will • if the colour is due to arsensio, as, if **» deposit of yellow tint will be formed 11 the crystal, ON THE CARPET." ^ami'iar saying, "On ih<J carpet, th French render sur le tapis" (on jx* Jable cloth) is said to have its origin from Oriental legend of Solomon's oarpet. The pastern writers say that Solomon had a green carpet, on which his throne was placed en he travelled. This carpet was large °ogh for a]i big forces to stand upon the and women stood on his right hand, and & "piriU on his left. When all were anged jn or(jer Solomon told the wind all w's^e^ to go, and the carpet with „ its contents rose in the air and alighted at 6 spot indicated. In order to screen the «™ty from the sun, the birds of the air with Spread wings formed a canopy over the °'e party. DRINKING WHILE EATING. Nature never intended people to wash down food while eating. She has wisely aoed salivary glands in various places in our in°Q^8' secrete a f°r the moisten- of the food while in the mouth. This gets j) 6. *°?d in a suitable condition for swallowing. Ven2 every few minutes while eating pre- «*■«,. usual flow of saliva, 8nd it washes it before it can exert its chemical action on am portions of the food. One of the pernicious habits to health is drinking ^^blers water while eating; better allow warm drinks. The stomach will not x one partiole of food when it has a JJJPerature below 100° Fahrenheit; neither o digest one atom of food until all the j, '<* is first absorbed. No healthy person drink more than a half-pint of some fluid while taking food, and dyspeptics fior f n°t drink a drop while they are eating, for three or four hours after. *L^CES OF SAFETY IN THUNDERSTORMS. old thunderstorms have confirmed the ^saying that it is dangerous to stand under during lightning. Isolated trees are apt to be struck than a clump, and tfjjaNy if they are near water. An oak o 1 a pond is considered by electricians u oring a particularly unsafe position. In as » T,a*er and damp ground are to be avoided, e'' as trees. On the other hand, to stand tr distance—say 50 or 100 yards from a WOo^°r» better still, from a clump of trees or 1'Rht '8 a fairly safe place, as the trees aotas, flijf n8 conductors. It would be safer to he 8tn °11 the ground than to stand upright if the is immediately overhead, which can be rtained by noting that the flashes and the ePort8 are simultaneous. Indoors it is dan- ^oua to sit near metal objects, such as ifrors, picture frames, and wire bell pulls; particularly near the fire, because the he t Srate, the soot, and the column of <c J1 gases in the chimney are likely to ^rraw'' the discharge, A safe plaoe is 4 leved to be the middle of a room, especially W0111 'a mi<*dle storey of the house; the' a?COr^"1gf to a distinguished physicist, stead6 a^' places is an iron or metal bed- jnex?i* °n this one is in a kind of **• c»ge, whioh acts as a lightning screen. To LOOSIm GLASS STOPPERS. COntemporaFy gives the following »tn M being effectual in loosening glass firiMPerS'—(^) Hold the bottle or decanter 6eun *n hand or between the knees and y tap the stopper on alternate sides, the purpose a small pieoe of wood, the ect'ng the strokes upward. (2) Plunge Oar ne°k °f the vessel in hot water, taking a that the water is not hot enough to split j. 6 glass. If the stopper is still fixed use the th ^thod. (3) Pass a piece of lint around f oeck of the bottle, which must be held ,while two persons draw the lint baok- CLan<?, forward. (4) Warm the neck of tot Ves8el before the fire, and when it is nearly fe the stopper can be removed. (5) Put a •fcU 0 around the stopper where it fS the glass vessel, which may then be Med before the fire. Then apply procegs 1- If the stopper still continues immov- repeat the above process until it gives °b it is almost sure to do in the end. the lake a steel pin or needle and run it round top of the stopper in the angle formed by the bottle. Then hold the vessel in toft' left hand and give it a steady twist lo ar,i you with the right, and it will very tj^11 effectual. If this does not succeed, ^process No. 5. which will soon be facili- by it. rj NUTRITIVE AND HYG?B??IC VALUE OF FRUITS. r» the physiological point of view, the v^ue of fresh ripe fruit depends on the aM acids and the alkaline salts the flavour ^rorna °f the fatty and ethereal oils, rj^'ch are present ia very minute quantities, of^. three aoids present in ffuit in the order the amount are malic, oitrie, and tartaric; W beirig the most common, and the (tartario), in grapes^ in ^greatest quan- It the question is regarded from the (revalue point of view, then the soluble con- of the dried fruit form the guide, oe .'t is found that apples contain per •> as compared with 81 for grapes, pears vrtol"ag next with 73 per cent. Plums follow IjgA?1 '2 per cent., and in this oonneotion are than cherries, which have only 67 per ^ato" soluble constituents after all the of ? 18 removed. Strawberies, from the point vjie* of food-value, are a long way in ad- ceft5e °f raspberries, as they have 67 per le fr of soluble constituents as compared with °r raspberries. Such figures are not, t0 +uVer» an altogether trustworthy guide as Uj- 6 value of fruits for dietetio purposes, as of the insoluble substanoes perform sjj lI> the human economy which is of con- fable value on the hygienio side of the Hj -Ripe fruits of all kinds are good for aQc* some of those which contain the ^or ^'eentagea of insoluble matters are even ficial, in some cases, than those nl( cb contain the larger amounts of the more tta.bly t aating canstituent* THE SOURCES OF BEAUTIFUL COLOUR. The cochineal insects furnish a great many fine colours. Among them are the gorgeous carmine, the crimson, scarlet carmine, and purple lakes. The cuttlefish gives the sepia. It is the inky fluid which the fish discharges in order to render the water opaque when attaoked. Indian yellow comes from the camel. Ivory chips produce the ivory black and bone black. The equisite Prussian blue is made by fusing horses's hoofs and other animal matter with impure potassium car- bonate. This colour was discovered accidently. Various lakes are derived from roots, barks, and gums. Blue-black comes from the char- coal of the vine stalk. Lamp-black is soot from certain resinous substances. Turkey red is made from the madder plant, which grows in Hindoostan. The yellow sap of a tree of Siam produoes gamboge the natives catch the iJap in cocoanut shells. Raw sienna is the natural earth from the neigh- bourhood of Sienna, Italy. Raw umber is also an earth found near Umbria and burnt. India-ink is made from burnt camphor. The Chinese are the only manufacturers of this ink. Mastio is made from the gum of the mastic tree, which grows in the Grecian Archipelago. Bister is the soot of wood ashes. Chinese white is zino, scarlet is iodine of meroury, and native vermillion is from quicksilver ore called cinnabar.
