Of oils and paints to keep off the mosquito there are many, 

 amongst others I can state from personal experiment that citronelle 

 oil kills two species of Anopheles at least, within 30 minutes, and 

 if renewed about every three hours upon exposed surfaces, it effectually 

 keeps them away. Antikito cream is well advertised, but I have no 

 personal knowledge of its efficacy ; it can be obtained from the Antikito 

 Syndicate, 6 Great Portland Street, London. 



Anti-mosquito measures generally speaking consist in: 1. Closing 

 all ponds ; 2. Draining all swamps ; 3. Covering all necessary water ; 

 4. Kerosining all large stagnant areas of water ; 5. Clearing the banks 

 of all slow-flowing streams and drains, and to the above I would add 

 from my own experience the felling of secondary jungle, and the 

 cutting of lallang in the vicinity of houses. 



In connection with malaria it must not be supposed that a rigor 

 (shivering fit) a hot stage, and a heavy sweat, comprise the whole of 

 the disease, as it has been definitely proved that malarial dysentery, 

 and diarrhoea occurs frequently in the tropics, and that the whole 

 question as to what symptoms malaria shows is dependent upon the 

 particular organ, or part of the body in which sporulation of the para- 

 site occurs, should sporulation take place in the brain, convulsions and 

 coma will be present, in the lungs a form of pneumonia, in the intes- 

 tines a form of dysentery, etc. Malaria is not the simple kindly 

 disposed disease which planters frequently imagine. 



Dysentery. 



I do not intend to deal exhaustively with this question, but I wish 

 to impress the fact that I believe the vast majority of dysentery cases, 

 as seen amongst coolies, have their origin either in malaria, or are of 

 a bacillary nature and highly infectious, the impossibilitv of separating 

 the two forms, from a layman's point of view, render a general rule 

 necessary, that rule is: Segregate all dysentery cases. 

 . Bilharziosis, when it affects the rectum produces symptoms 

 similar to dysentery, 



!f the health of an estate is a matt 

 dysentery case should be looked upon 

 lated immediately on its appearance. 



As a routine treatment a dose of castor-oil, with say 20 drops of
