PAINS AFTER EXERTION.—It is not generally known to pedestrians that the pains in the knees and legs, which usually follow after a long excursion, and which continue with some persons for two or three days after, may be prevented or considerably lessened, by bathing the parts affected in cold spring water, immediately before going to bed. Care should be taken, if the feet be dipped in the water, afterwards to dry them thoroughly with a rough towel; and persons of weak constitution, or liable to cramp, _ought not to dip their feet at all_. Those who reside at the sea-side, if of sound strong constitutions, will find great relief in the summer months, by bathing in the sea, but this practice ought not to be adopted without great caution. In my own case, and that of two of my brothers, it has proved invaluable for restoring vigour and energy to the system, after a long and tiring walk.—F. J. L., _Margate_. TO HEAL BURNS.—Steep the bark of sumach-root, and boil it away until it is very strong; then add hog’s lard, and boil it until the water has all evaporated. A little of this applied to a burn will check the inflammation instantly. It has been known to cure dangerous scalds when physicians’ remedies have failed.—S. CERTAIN CURE FOR CRAMP IN THE LEGS.—Stretch out the heel of the leg as far as possible, at the same time drawing up the toes as far as possible. This will often stop a fit of the cramp after it has commenced. I have never known this fail.—E. J. CALAMINE OINTMENT, OR TURNER’S CERATE, consists of half a pound of yellow wax, and a pint of olive oil, which are to be melted together; this being done, half a pound of calamine powder is to be sifted in, and stirred till the whole be completely mixed. This is an excellent ointment for stimulating sluggish wounds or sores. BLEEDING AT THE NOSE.—To stop this malady, which is sometimes alarming, it is recommended by Dr. Negrier (who has extensively tried it) simply to _elevate the patient’s arm_. The explanation is based upon physiological grounds: the greater force required to propel the blood through the vessels of the arm when elevated, causes the pressure upon the vessels of the head to be diminished by the increased action which takes place in the course of the brachial arteries (the arteries of the arms). If the theory be sound, _both_ arms should be elevated.
