    Out of 176 Government servants, 118 were attacked between the 10th September and 31st December. Ships came in and could not discharge their cargoes. The outbreak was so bad that the High Commissioner ordered the closure of the port until it could be made more sanitary. In the meantime Watson had recommended measures similar to those taken at Klang, and a special commission appointed by Government adopted them. Within six weeks the work of the port was proceeded with without great difficulty. An area of about 100 acres was bunded and drained and freed from jungle. The results were immediate and decisive. The author had kept careful hospital statistics, including returns of all cases in individual houses, from facts known to him in his capacity as District Surgeon. The figures are given in a series of papers by him and Dr Travers {Journal of Tropical Medicine, 15th September, 16th November, 1st December 1903, 1st April 1905, 2nd July 1906). I attach the following abstract from my paper [1907]. 1.
