Notes on Some Other Works. — It is impossible to give within the limits of this book a full account of all the campaigns which have been commenced, or even to mention some of them ; but I think that brief notes on the following works should be added. (i). India.—In section 7 I described my own work in India up to the publication of a report [1899] in which I suggested my proposals for mosquito reduction. By this time I had left India; and no notice was taken of the report, except that several medical men wrote against the idea. They pointed out that Anophelines breed in rice-fields, and so on, near canton- ments, and therefore thought that the task of banishing them would be impossible. They evidently failed to understand my arguments, and had no idea of the economical principle laid down in axiom 3 of section 38. At this time many persons were writing up the recent discoveries. Unfortunately, some of them were not personally acquainted with the tropics, and few of them had any know- ledge whatever of practical tropical sanitation. It was almost impossible to make them understand my proposals; but some of them clamoured for a formal experiment to test them in the field. I was very averse from this suggestion. Success would demand a long and patient enquiry, requiring an exact preliminary survey of the amount of malaria and the number of mosquitos present, followed by equally exact measurements of these quantities made on frequent occasions. Now it will be seen from Chapter V how difficult it is to measure malaria](https://iiif.wellcomecollection.org/image/b21351600_0640.jp2/full/800%2C/0/default.jpg)
