 or water-plants along the shore of the canal. The 

 breeding places of the anopheles having been deter-

 made, and house drains and sinks oiled and collections 

 of stagnant water removed. These measures liave 

 brought about a remarkable disappearance of mosquitos 

 and flies of all kinds, whilst anopheline larva? have

 town at a distance of some 1,800 metres from the 

 outlying houses. Since 1905 no case of malaria has 

 been reported in Ismailia. 



On February 7, 1904, sixteen months after my 

 colleague Ross's visit, I was invited by the courteous

 inland sea-bathing resort for the Cairenes, out of what 

 was, until two years ago, a mosquito-plagued town 

 and a nest of malaria. 



In the old days, previous to the antimalarial 

 measures, the carefully planted town and well-placed
