308 LUC Wind.--The prevalent wind during the hot months is westerly. There are on the average 27,000 miles of wind every year; this would give an average of nearly 74 miles per day. March, April, and May are the most windy months. Hailstorms have not done serious damage since 1868. The wind generally is quite strong enough for a wind-mill, which might apparently be tried on a large scale in Lucknow for irrigation purposes, A wind-mill, with sails of 40 feet radius, is equivalent to 65,000 feet pounds per minute, Storms. There are four or five storms nearly every year, mostly in the months of April and May. Since 1868 there have been registered three storms, with a pressure of 40lbs. per square foot. In 1873-74 there was no storm with a greater pressure than 104lbs., but this is probably incorrect, as the registered velocity indicates a much higher pressure. In all the preceding years the registered pressure has reached 25-30 or 40lbs. In 1869 only 201bs. were reached. Sanitary and medical aspects.-The mortuary returns and statistics are so incorrect that no reliance can be placed upon them. The reported deaths in 1872 in Lucknow were 148 per mille of the population ; in 1870 they were 10:36 in the rural district, and 25:82 in the city; in 1871, the rate was 19 8 in the city, and 12-5 in the district; fever is credited with about half the mortality.+ Small-pox is very prevalent in Lucknow, but it is of a mild type. Only about one per cent of the deaths are credited to it, although the large majority of the people have suffered from it, and some from repeat- ed attacks. Cholera has not of late been very destructive; but in 1872, 2:11 per mille are recorded to have fallen victims to it. The ci vil sur- geon states that the native drugs are worthless, and the Yunani system of treatment mere charlatanry. The following memorandum on the ne- dical aspects of the Lucknow district is supplied by Bábu Chandi Charan Ghose, assistant to civil surgeon :- "No trustworthy statistics exist as to the annual birth rate in the district of Lucknow; and even the registration of deaths in the city of Lucknow and the seven rural circles is not as perfect as is to be desired. The population of the district-according to the latest publication in the Oudh Government Gazette of 21st November, 1874-is 778,195, and the number of deaths registered in the district during 1873 is 10,288, giving the ratio of 13-22 of deaths per thousand of the population. The mean ratio of deaths per thousand during the previous three years was 16-28. All this information has been collected from the inortuary returns, but as doubts have been expressed about the correctness of these returns, the figures given above must be taken with a certain degree of allowance. The prevailing endemic diseases in the district are fevers, skin diseases, and bowel complaints. Fevers are met throughout the year ; but their prevalence during three months—September, October, and November • Chambers' Encyclopædia, Article Wind-mills, Fairbairn's Mills, Vol. 1, pagca 6, 282,295; Murray's band-book to the Contioent, pagca 12, 18, quoted in Kheri district article. t The Civil Surgeon aaya that lie cannot give any trustworthy faets bearing on the medical aspects of the Lucknow city and district,
