=Cancer.=--It is well proved that cancer cannot be successfully removed by use of the knife. Surgeon John McFarlane, of Glasgow, mentions the cutting out of _eighty-six_ cancers without effecting a _single cure_. For those who are troubled we would say that there have been and there are remedies with permanent effects. The writer knows of a female physician in this city who has been very successful in achieving lasting cures in numerous authenticated instances. =Chewing Gum and Other Substances.=--Regular chewing outside of meal hours of any substance is injurious. It unnecessarily excites the salivary glands, the strength of which should be reserved for eating. Do not chew the ends of your finger nails. Little pieces of the nails may be swallowed, which at some time--possibly quite remote--may cause you great pain, and even death. This has occurred. It has also been found by opticians and doctors that hardly anything will affect the eyes harmfully quicker than gum-chewing. =Cholera.=--Dr. Gamaleia, of Odessa, claims to have discovered a prophylactic against cholera, and hopes to win the prize of $20,000 offered for such a cure. He calls his specific Chemical Vaccine, and has tried it efficaciously on apes, guinea-pigs, and pigeons. This is obtained by the successive passages of cholera virus through the blood of animals. After each of these passages, the virus becomes stronger, and is finally injected into the patient. A cure which was very effective when the cholera struck America is called the "Sun Cholera Medicine." It is also an excellent remedy for colic, and diarrhea, etc. Take equal parts of tincture of cayenne pepper, tincture of opium, tincture of rhubarb, essence of peppermint, and spirits of camphor. Mix well. Dose: 15 to 30 drops in a little cold water, according to age and violence of symptoms, repeated every fifteen minutes or twenty, until relief is obtained. Our own _infallible_ remedy for cholera, cholera morbus, cramps, colic, and diarrhea, is:-- Tincture of opium, 3 drachms. " " cayenne pepper, 5 drachms. " " ginger, 5 drachms. " " camphor, 3 drachms. Dose: 1 teaspoonful in a gill of cool water for an adult; repeat with half a teaspoonful in 15 minutes if not relieved. For a child 2 years old 1/4 the above dose, and in proportion up to an adult. =Cleanliness.=--The English upper classes are clean, but cleanliness of any high degree is a modern virtue among them. It is an invention of the nineteenth century. Men and women born at the close of the eighteenth century did as French people do to-day; they took a warm bath occasionally for cleanliness, and they took shower-baths when they were prescribed by the physician for health, and they bathed in summer seas for pleasure, but they did not wash themselves all over every morning. However, the new custom took deep root in England, because it became one of the signs of class. It was adopted as one of the habits of a gentleman.
