fever, particularly how to avoid getting it, and you will find the most dogmatic of these are people who have been singularly unlucky in the matter, or people who know nothing of local conditions. These latter are the most trying of all to deal with. They tell you, truly enough no doubt, that the malaria is in the air, in the exhalations from the ground, which are greatest about sunrise and sunset, and in the drinking water, and that you must avoid chill, excessive mental and bodily exertion, that you must never get anxious, or excited, or lose your temper. Now there is only one—the drinking water—of this list that you can avoid, for, owing to the great variety and rapid growth of bacteria encouraged by the tropical temperature, and the aqueous saturation of the atmosphere from the heavy rainfall, and the great extent of swamp, &c., it is practically impossible to destroy them in the air to a satisfactory extent. I was presented by scientific friends, when I first went to the West Coast, with two devices supposed to do this. One was a lamp which you burnt some chemical in; it certainly made a smell that nothing could live with—but then I am not nothing, and there are enough smells on the Coast now. I gave it up after the first half-hour. The other device was a muzzle, a respirator, I should say. Well! all I have got to say about that is that you need be a better-looking person than I am to wear a thing like that without causing panic in a district. Then orders to avoid the night air are still more difficult to obey—may I ask how you are to do without air from 6.30 P.M. to 6.30 A.M.? or what other air there is but night air, heavy with malarious exhalations, available then?
The drinking water you have a better chance with, as I will presently state; chill you cannot avoid. When you are at work on the Coast, even with the greatest care, the sudden fall of temperature that occurs after a tornado coming at the end of a stewing-hot day, is sure to tell on any one, and as for the orders regarding temper neither the natives, nor the country, nor the trade, help you in the least. But still you must remember that although it is impossible to fully carry out these orders, you can do a good deal towards doing so, and preventive measures are the great thing, for it is better to escape fever altogether, or to get off with a light touch of it, than to make a sensational recovery from Yellow ack himself.
There is little doubt that a certain make of man has the best chance of surviving the Coast climate—an energetic, spare, nervous but light-hearted creature, capable of enjoying what-
