General Rules for Disinfection.--The walls, woodwork, and ceiling may be cleaned by washing with one to one thousand solution of corrosive sublimate solution, or a five per cent carbolic acid solution, Or by rubbing with bread if solutions would injure. All dust must be removed. Plastered walls and ceilings may be white-washed. Woodwork must then be scrubbed with soap and thoroughly wiped. Then fumigate, at least three pounds of sulphur should be burned in the room for each 1,000 cubic feet of space. Placing it in a pan supported in another containing water to guard against fire.

Clothing, bedding, etc., may be disinfected in the steam sterilizer. Hands, Body, etc.--Special outer garments may be worn while in the sick room and removed, and clothing aired before leaving. Hands of the attendant should be washed in one to one thousand corrosive sublimate solution. Vaccination and Re-vaccination and its Prevention of Smallpox. We quote in part from an article prepared by the State of Michigan. It is well known that smallpox can be prevented or modified by vaccination; and a widespread epidemic of the disease can be attributed only to an equally widespread ignorance or willfulness concerning smallpox and its prevention by vaccination and re-vaccination. A Good Time to be Vaccinated.--Smallpox is usually most prevalent in the winter and spring months, reaching the highest point in May. The rarity of smallpox in Michigan for several years led to a feeling of security and to neglect vaccination, resulting in an increased proportion of inhabitants not protected by recent vaccination. This made possible a widespread epidemic. The proper preventive of such an epidemic is general vaccination and re-vaccination of all persons not recently thus protected. There is no better settled fact than that vaccination does protect against smallpox. But after a time the protection is weakened, therefore after a lapse of five years there should be re-vaccination.
