ADDITIONAL USEFUL HINTS. 617 



GTUttfl. percha ; put in a wide-mouthed bottle ; shake frequently ; at the end of two 

 weeks strain through a cloth, return to bottle and cork tightly, for reasons that 

 will be obvious. To apply, first dry the article, then smear the cement on and 

 allow it to evaporate, before bringing edges together. After it has become light- 

 colored in spots, warm and bring edges perfectly together ; stand away for awhile 

 and the job is complete. 



J . Four ounces of pure India rubber, one-eighth of an ounce powdered asphal t- 

 am, put together in a tin can, then add about six times the quantity of benzine, let 

 it stand three or four days, then take a stick and work it over, then add benzine and 

 stir it well until you have it about the consistency of lioney ; then it is ready for 

 use. It should be covered as tight as possible while dissolving, and afterward. 

 To use it, scrape the polish from the rubber, then apply the cement to the place to 

 be mended, and also to a piece of rubber to be used as a patch. Dry half an hour, 

 and apply another coat, then, after another half hour, press the patch into the 

 place over the break. Like all other preparations containing benzine, it must 

 be kept away from fires, as it is as explosive as burning fluid. 



3. Cut virgin or native India rubber with a wet knife into the thinnest possible 

 slices, and with shears divide these into threads as fiue as fine yarn. Put a small 

 quantity of the shreds (say one-tenth or less of the capacity of the bottle) into a 

 wide-mouthed bottle, and fill it three-quarters full of benzine of good quality, 

 perfectly free from oil. The rubber will swell up almost immediately, and in a 

 few days, especially if often shaken, assumes the consistency of honey. If it in- 

 clines to remain in undissolved masses, more benzine must be added ; but if too 

 thin and watery, it needs more rubber. A piece of solid rubber the size of a wal- 

 nut will make a pint of the cement. This cement dries in a few minutes, and by 

 using three coats in the usual manner, will unite leather straps, patches, rubber 

 soles, backs of boots, etc., with exceeding firmness. The India rubber, unvul- 

 canized, can be obtained at most large stores where rubber goods are sold, and at 

 some drug stores. 



Sleeping in a Cold J^oam.— People who come in from along period of out-door 

 camping are almost certain to catch cold in a house when they return, because, 

 having been accustomed to sleeping in the open air, they almost invariably leave 

 their windows open. Many persons who went to bed well, are surprised to wake 

 up in the morning with inflammation of the lungs, solely because they have 

 hoisted the windows for ventilation. Hall's ypumal 0/ Health says that robust 

 persons may safely sleep in a temperature of forty or under, but the old, the 

 infant, and the frail should never sleep in a room where the atmosphere is much 

 under fifty degrees Fahrenheit. 



If there is some fire in the room all night the window may be opened an inch. 

 It is safer to sleep in bad air all night, with a temperature over fifty, than in a pure 

 air with the temperature under forty. The bad air may sicken you, but cannol 

 kill you ; the cold air can and does kill very often. < 



Colds and Headaches. — Take of Norwood's tincture veratrum one drop on a 

 small Ium;5 of sugar every two hours, and a three-quarter quinine pill every three 

 hours. This prescripiion is recommended by Dr. N. Rowe, of the Chicago Field. 



■d. Dissolve fifteen or twenty grains of chloral in very little water, and with the 

 tip of a finger rub it upon the seat of pain until you can sensibly feel the burning 

 and the skin is reddened. 



Fever DzeL—Whea a patient will not take beef tea in the ordinary form, freeze 

 t, and administer in small umps. In this way it forms a most palatable article 

 Qf diet.
