Different parts of the oriental world have been mentioned as the probable locality of the first appearance of the plague or pestilence known as the "black death," but its origin is most generally referred to China, where, at all events, it raged violently about 1333, when it was accompanied at its outbreak by terrestrial and atmospheric phenomena of a destructive character, such as are said to have attended the first appearance of Asiatic cholera and other spreading and deadly diseases; from which it has been conjectured that through these convulsions deleterious foreign substances may have been projected into the atmosphere. But while for centuries the nature and causes of the black death have been subjects of medical inquiry in all countries, it remained for our own time to discover a more scientific explanation than those previously advanced.

The malady is now identified by pathologists with the bubonic plague, which at intervals still afflicts India and other oriental lands, and has in recent years been a cause of apprehension at more than one American seaport. It is called bubonic - from the Greek boubon ("groin") because it attacks the lymphatic glands of the groins, armpits, neck, and other parts of the body. Among its leading symptoms are headache, fever, vertigo, vomiting, prostration, etc., with dark purple spots or a mottled appearance upon the skin. Death in severe cases usually occurs within forty-eight hours. Bacteriologists are now generally agreed that the disorder is due to a bacillus identified by investigators both in India and in western countries. (J. Hatcher)
The first historic appearance of the black death in Europe was at Constantinople, A.D. 543. But far more widespread and terrible were its ravages in the fourteenth century, when they were almost world-wide.................
