History.--Leprosy is supposed to have originated in the Orient, and to be as old as the records of history. It appears to have prevailed in Egypt even so far back as three or four thousand years before Christ. The Hebrew writers make many references to it, and it is no doubt described in Leviticus. The affection was also known both in India and China many centuries before the Christian era. The old Greek and Roman physicians were familiar with its manifestations, ancient Peruvian pottery represent on their pieces deformities suggestive of this disease. The disease prevailed extensively in Europe throughout the middle ages and the number of leper asylums has been estimated at, at least, 20,000. Its prevalence is now restricted in the lands where it still occurs while once it was prominent in the list of scourges of the old world. It is now found in Norway and to a less extent in Sweden, in Bulgaria, Greece, Russia, Austro-Hungary and Italy, with much reduced percentage in middle Europe; it is the rarest of diseases in England where once it existed. In India, Java, and China, in Egypt, Algiers, and Southern Africa, in Australia and in both North and South America, including particularly Central America, Cuba, and the Antilles, it exists to a less extent. It has been recognized in the United States chiefly in New Orleans, San Francisco, (predominantly among the Chinese population of that city). The disease has steadily decreased among the latter colonists in Minnesota, Wisconsin and Iowa. Isolated cases have been recognized in almost every state, and leprous cases are presented at the public charities of New York, Philadelphia, Boston, etc. The estimated number of lepers a few years ago in the United States varied between two hundred and five hundred. It is represented as diminishing in frequency in the Hawaiian Islands, Porto Rico and the Philippines. In the Hawaiian Islands it spread rapidly after 1860, and strenuous attempts have been made to stamp it out by segregating all lepers on the island of Molokai. There were 1,152 lepers in that settlement in 1894. In British India, according to the leprosy commission, there were 100,000 lepers in 1900. Cause.--The bacillus, discovered by Hansen, of Bergen, in 1874, is universally recognized as the cause of leprosy. It has many points of resemblance to the tubercle bacillus. These bacilli have been found in the dwellings and clothing of lepers as well as in the dust of apartments occupied by the victims. [238 MOTHERS' REMEDIES]
