Cholera. Cholera. 4 Cases. 4 Deaths. Four fatal cases of Cholera confirmed bacteriologically, occurred during November. The infection was brought by one of the victims from India, the vehicle being, it is believed, some sweet-meats purchased before leaving Tuticorin. Three of the deceased were brothers, and the fourth was a friend who lived in an adjacent tenement. 20. Small-pox and Vaccination. Cases, 48. Deaths, 10. A case of Small-pox imported in March from Bombay during the incubation period, led to a small outbreak in the town with 86 cases, 5 of which died. In addition to these, 6 cases were admitted to the Hospital from the Port, and 6 from places outside the town. Three of the Port and two of the outside cases died. The town cases were on the whole of a fairly mild type, 15 being modified, 11 discrete, and 10 confluent. There were 6 cases of concealment in all of which prosecutions were entered and convictions obtained. Only one of the town cases, a child of 7 months, was definitely known to be unvaccinated ; in 5 of the confluent cases the presence or absence of vaccination marks was unascertainable owing to the Small-pox eruption ; all the other cases bore old marks of vaccination. As this and previous outbreaks have repeatedly demonstrated, primary vaccination in Colombo is good ; what is required to prevent epidemics here is revaccination.](https://iiif.wellcomecollection.org/image/b31753498_0030.jp2/full/800%2C/0/default.jpg)
