=Small-pox and Vaccination.=--Notwithstanding existing prejudices, statistics prove the great usefulness of vaccination. In small-pox epidemics, of those persons attacked who have not been vaccinated, one case in four is fatal; while of those who have been vaccinated, the death rate is not one in four hundred and fifty. In cities, it is important that every infant should be vaccinated before it is six months old. In the country, the operation may be deferred until the infant is a year old. Care should be taken to have the virus fresh and from the cow. The taking of virus from a child, or an adult, should never be allowed, as constitutional diseases are often transmitted in that way. Vaccination is performed by making a small incision in the skin and introducing the virus on the point of a lancet or needle. On the third day, if the desired result has been attained, a small red spot may be seen. This increases in size, becomes elevated, and, by the sixth day, is filled with a clear, yellow liquid. About the eighth day, the pustule is fully formed, when symptoms of small-pox are usually felt,--headache, shivering, loss of appetite, etc. These symptoms subside in a day or two; the fluid in the pustule dries up, and a scab forms, which remains about two weeks and then disappears, leaving a scar. The affected part should be protected by a loose bandage, and all scratching or rubbing prevented. The theory in regard to vaccination is that the disease in a mild form takes hold of the system, and either completely or partially destroys the liability to contract the same disease in the future. If the destruction is only partial, it can be made total by future vaccinations. All authorities agree that it is necessary to revaccinate frequently--just as often, in fact, as the system shows itself in readiness to take the vaccinations. Then as often as once in five or seven years vaccination should be repeated in order to obtain complete immunity from small-pox. =Superstitions.=--Numerous are the dangerous superstitions about marriage. For instance, the bride must not try on her wedding gown, or ill-luck will follow. She must not look in the glass after she is fully dressed and ready for the ceremony. She must not enter her new home by stepping over the threshold, but must be carried over it by one of her relatives. A piece of the bride's cake must be broken over her head as soon as she is safely on the other side. It is very unlucky for her to be in a happy state on her wedding-day. She must be as dolorous as possible, violent fits of weeping being especially beneficial.
