?10 during the seven years or so in which the harbour works have been in progress. Captain Glen Liston, I.M.S., who has written on the subject, has referred to this association of the harbour works and malaria. He says :-" Moreover, it assumes an additional interest in view of the fact that the present epidemic seems to be associated in some way with the construction of the new docks." In the few days that we had at our disposal we were able to see, owing to the kindness of Captain McKendrick, I.M.S., who is engaged in anti-malaria work in Bombay, the conditions associated with this epidemic. The works in question covered an extensive site; immediately outside this along the Frere Road was the part of Bombay most severely affected, though the condition of epidemic malaria extended for nearlly half a mile into the city as ascertained by Captain McKendrick in his preliminary enquiries. We satisfied ourselves that here we had, in addition to many in- teresting points we have not the space to touch upon,- (1) The formation of a focus of intense malaria by a large labour aggregation. (2) The implication secondarily of the inhabitants of Bombay. That there existed indeed an aggregation of labour which was involving not only a few European and others connected with it, as in the Duars, but a large portion of the very heart of a populous city, a portion that should otherwise have been almost free from the disease.
