The terrible plague of the Black Death that swept over Europe from 1347 to 1350 was a malignant form of the bubonic plague. Over 1,200,000 people died in Germany, and Italy suffered much more. In Vienna for some time about 1000 people a day died and were buried in great trenches. Venice lost 100,000 inhabitants, and London lost more than that. In both Padua and Florence only one-third of the inhabitants were left alive; at Avignon the Rhone was consecrated so that bodies might be thrown into it for burial; and ships drifted about the coasts of Europe {185} with dead crews. Hecker, in his study of this plague, says that nearly one-fourth of the population of Europe died in that visitation. Civilisation was wellnigh overthrown in the panic. In Germany, Italy, and France the Jews were accused of poisoning the wells and thus causing the plague, and they were slaughtered by thousands. At Strasburg 2000 Jews were burned to death in one holocaust; at other places, as at Eslingen, in despair the Jews set fire to their synagogues and destroyed themselves. The Great Plague of London in 1665, in which 70,000 persons died, was also the bubonic plague. The mortality is about 90 per centum in some epidemics. The bacillus leaves the body in the faeces, flies carry it to food, it thus gets to rats and mice, and it is carried from place to place. Rats, however, are commonly infected as if by a miasm before the disease appears in man. There is dispute as to the communicability of the plague from man to man by contact with fomites, but it is practically certain the disease can be thus transmitted. Kitasato once succeeded in producing the disease in animals by inoculation with dust taken in an infected house. Merely touching a patient does not apparently convey infection, yet some authorities hold that in time of epidemic the contagion is transmitted even through the air, especially on the ground floor of houses. Perhaps mosquitoes are the medium of infection, as they are inclined to fly low. In visiting a case of bubonic plague the priest should be as cautious as if he were attending a smallpox patient. After death by smallpox, plague, typhus, cholera, scarlatina, diphtheria, and measles the funerals should be private and the bodies should not be taken to the church. Malta Fever, or bilious remittent fever, is found in some of the islands taken from Spain. It has a low mortality and is not contagious. Bruce in 1887 isolated the bacterium that causes it.
