sketch briefly the* principal symptoms which lead one to suspect 
serious disease, and suggest a sound amateur treatment to be adopted 
in such cases. 
Malarial Fever. 
The principal disease to which the coolie is liable is Malarial 
Fever, but if the attacks of this disease remain discrete by wmch 1 
mean so long as the attacks are separated by a day or days— one may 
safely deal with him on the estate by the administration of quinine 
in 5 gr. doses thrice daily, if, however, the attacks overlap, and the 
disease becomes continuous, then an hospital is the proper place tor 
the case. When it is found that the fever yields to quinine the drug 
should be continued in 5 gr. doses daily for two (2) months, the 
neglect of this most important “ regime of prophylaxis is the cause 
of the relapse cases whicff cause so much invaliding and disturbance 
of estate work quite unnecessarily. 
The necessity of sleeping in mosquito curtains must be ‘‘rubbed 
into” coolies ; the Chinese have adopted them and there is absolute y 
no reason why the Tamil should not be educated up to their use. At 
the meeting of the Malaya Branch of the British Medical Association 
held at Ipoh on August 28th and 29th, 1906, my friend Dr. Malcolm 
Watson of Klang, pointed out the advisability of mosquito-proofing 
all lines, and he laid before that meeting most convincing statistics 
to show that the saving of life and labour from the ravages of malaria 
by this means, amply repaid planters for their original outlay on wire 
gauze. I am strongly in favour of this measure where it is feasible, 
but curtains must be supplied where serious obstacles to its adoption 
exist. . „ c 
% In dealing with the question of fever the mosquito naturally 
comes under notice, and before starting upon the means to be adopted 
to combat the existence of this pest, 1 must first make my peace with 
some planters who still believe that this insect is not the only means 
of propagation of malaria, by stating that the malarial parasite ha,s 
been constantly found in the “stomachs of certain mosquitos, but it 
has not been found in decomposing granite, nor in any of the other 
earths and clays, etc., which have been blamed as distributors or pro- 
pagators of the disease. All experiments with infected Anopheles 
have been positive, and I am quite willing to guarantee or gamble on the 
result of the experiment of infecting any new-comer to this country by 
the means of infected Anopheles, provided the doubting planter will 
make the necessary arrangements with his newly-arrived assistant. 
Mosquito houses were the only means adopted by the Commission 
sent out by the London School of Tropical Medicine to that hotbed 
of malaria the Roman Campagna, and no cases occurred amongst 
the members of the expedition, and again, the European who submit- 
ted himself to the bites of Anopheles which were infected 48 hours
