?187 In connection with the above it may be interesting to note the density of population in a few districts in the City :- District. Area in Acres. Population. Density per Acre. Kamatipura ... ... 66 29,203 441.5 Dhobi Talao ... ... 97 29,945 407.7 Kumbar Wada ... ... 46 32,209 699.3 Khara Talao ... ... 41 27,033 649.3 Bhuleshwar... ... 75 38,361 506 in all of which districts plague raged with more or less virulence at various times. In comparing this with the City of London it may be mentioned that the greatest density of that town is probably not more than 222 persons per acre. Plans Nos. 11 and 11a show the progress of the disease in Worli Koliwada. The events which accompanied the course of the disease in this village are exceedingly interesting. Worli Koliwada is an isolated village on a peninsula in the north of the Island ; it is inhabited almost entirely by Kolis (fishermen). The number of houses in the village is 936, and the normal population is 5,493. The character of the disease was marked by extraordinary virulence, over 90 per cent. of the persons attacked dying, often after a few hours' illness only. The houses are mostly kutcha-built with cadjan roofs, which are in many cases brought down so low as to render the inside very dark. The streets are exceedingly narrow. There is no artificial drainage, but good natural drainage exists from west to east ; the whole village is open to the sea-breeze on two sides. During the months of October and November 1896 there is no record of any case of plague having been present in the village ; the first case being reported on December 1st. The villagers were fully alive to the dangers of the disease and of its getting into the village, and they took extraordinary precautions. The three patels, headmen of the village, agreed among themselves as far back as October to prevent strangers entering the village, by placing watchmen at the entrances, and to allow no persons to proceed from the village to any affected part of Bombay ; they even went so far as to object to the usual Municipal coolies visiting the village for cleansing purposes. But all this was of no avail, as a Koli (named Roza Maria Creado), resident of the village, died on December 1st. No further deaths occurred till December 11th. Plan No. 11 is on a horizontal scale of four days to one inch and a vertical scale of four deaths to one inch. It will be seen that the deaths have been grouped Nos. 1, 2, & 3. On plan No. 11a the deaths have been shown in the houses in which they occurred by circles colored in the respective colors of the groups (either 1, 2 or 3) which they represent.
