so characteristic and disagreeable, the diluted carbolic acid solutions are probably the best.  If the eruption is abundant on the scalp the hair should be cut short.  During, convalescence frequent bathing is advisable.  It should be done daily, using carbolic soap freely in order to get rid of the crusts and scabs.  There is danger to others as long as the skin is not smooth and clean, and not free from any trace of scabs.  As you must have a physician, I give but little medical treatment.  Nursing is the main thing in this disease.

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.  After scrubbing or fumigating, the room and its contents should be freely aired for several days, admitting sunlight if possible.  All useless articles and badly soiled bedding should be burned.  Such pieces of clothing as will not be injured may be boiled or soaked in a one to one thousand formaldehyde solution (one ounce of twelve per cent solution in one gallon of water), or two per cent carbolic acid solution.  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.
