?80 284. On the question of the period occupied by the incubation of cholera, though precise information is rather wanting, there is sufficient evidence that the period varies from a few hours to two days. It does not, however, neces- sarily follow that because a person who has been exposed to the contagion of cholera does not exhibit symptoms of the disease after a period of two days has elapsed he is no longer capable of communicating the disease; the contagion, though it may have no effect on the individual, may continue for a longer period to cling to his person or clothes. 285. The proportion of deaths to cases according to the returns, was in Seonee 66 per cent, in Jubbulpore 71.2. These figures probably approximate the truth; the rate of mortality among persons attacked, however, varies greatly in different villages. In many that I inspected two or three persons were pointed out as the sole survivors of from 30 to 40 attacked; in others, as at Ghunsore (para. 100), the large proportion that recovered had been noticed by the villagers themselves. 286. The duration of the epidemic in different towns and villages varied greatly. In the large towns, as in Jubbulpore and Saugor, though it never assumed any great proportion, it continued to prevail for several months; in the villages, however, the duration was comparatively short,- some appear to have passed through the ordeal in from three or four days to a week, but the more common periods ranged from a fortnight to three weeks. The town of Mundla in the present year afforded a remarkable instance of the occasionally rapid rise and decline of cholera. Here, in the first week of the epidemic the deaths amounted to 13, and in the second week they rose to 80, in the third the number declined again to 9. 287. In illustration of several of the points above adverted to, I may here recount the circumstances of an out-break of cholera reported by the Deputy Commissioner of Chindwara, and verified by him at the time :- On the 23rd April a woman left the town of Saosur to go to the village of Jhimillee, 17 miles distant. Cholera had appeared at Saosur previously, and it is said that the woman herself had shown symptoms of the disease before she left; at any rate she arrived at Jhilmillee shortly before sunset with the disease fully developed. She did not enter the village, but lay down at a well 50 yards outside, where she died. The Kotwal buried her that night, and the next day he, his son, and his daughter were all seized and died in a few hours. On the same and following days (24th and 25th) 29 persons were attacked, of whom 27 died on these dates. On the 26th a general flight from the village took place, and it does not appear that any died subsequently. On the 27th the Malgoozar, who lived in another village, hearing of the out-break, went to enquire, when he found the village deserted, with the exception of two women who were ill, and who died that night. He at once reported the matter to the Police. On the 30th the Circle Inspector, with a Native Doctor sent by the Deputy Commis- sioner, arrived, and found that the people had returned; and no case had occurred since their return. The Inspector described the village as in a very filthy state; the only water which the villagers used was that of the well at which the women leakage from a sink drain and the soil pipe of the water closet. The contamination of the well water was not of recent date. Early in June the head of the family had consulted a medical practitioner in London, he was then suffering from obstinate indigestion and irregularity of bowels, particularly a desire to go to stool immediately after taking food, and his health had been disordered for months. As the wife and her mother were suffering from the same symptoms, the medical practitioner suspected the water used by the family might be impure, and on a specimen being subjected to chemical analysis this was found to be the case. Notwithstanding this discovery, the faith of the family in the goodness of the water was not shaken, and they persisted in its use till the out-break of cholera. On the recommendation of their medical adviser, the head of the family and his wife had visited Weymouth; it would appear, however, from the former having suffered from an attack of bowel-complaint shortly before leaving Weymouth, that the change had not been sufficiently continued to remove the effects of the long continued use of impure water, and it would appear also that in consequence of the extreme susceptibility to cholera produced by this cause, that the pair had become infected with the disease while passing through Southampton.
