In the year 1813 a report was published by the Imperial Institution of France, which stated that 2,671,662 subjects had been properly vaccinated in France, and that only seven of these had afterwards taken the small-pox. In Prussia the number of persons who died from small-pox was reduced from 40,000 annually to 3,000. Although it is not yet settled beyond doubt, tliere seems to be Fig. 37.—Micrococci in the fresh Ltmph of Human Small-pox. 1. Singly. 2. In dumb-bell-like pairs. 3. In short chains {after Klein).. Fig. 38.—Lymphatic Vessel from the Skin of a Pock in the CASE OF Sheep-pox. The vessel is seen to be filled with micrococci. every reason to believe that variola depends upon the presence of a special and very minute micrococcus. Cohn found that the lymph of vaccinia and that of variola contains numerous micro- cocci. That the lymphatic vessels of the skin near the pocks are lull of micrococci, has been shown by Weigert in the case of small-pox of man, and by Klein in the case of shoep-pox. The passage of these micrococci through the epidermis at the point of vaccination in the calf has been traced by Pohl-Pmcus. When cultivated on the warm stngo, and subjected to examina- tion by the microscope, the microcdcci are seen to form very long chains and colonies. Still, as Dr. Klein points out, similar micrococci occur in the fluid contents of vesicles in the skin.
