It is almost needless to remark that care is required in the matter of diet. During the febrile periods “slops” only should be given, and then in not too large quantities at a time; but in those cases where there is a distinct fever-free interval between the paroxysms of the disease, a great deal of license may be allowed, and solid food of a light digestible sort is often not only well tolerated, but even beneficial, while it is almost needless to say that these intervals of returned digestive power should always be seized upon to get a liberal supply of quinine into the system. During convalescence the administration of 10 to 15 grs. a day of quinine should be maintained for at least a week after the disappearance of all febrile symptoms, and some ordinary tonic, such as Easton’s syrup, is often useful in facilitating the return to strength. The least sign of a relapse, as evidenced by a rise of temperature, of however temporary a character, should be met with a further treatment with quinine for at least a week or ten days, as it is a clear sign that the disease is scotched, but not killed, and that some of the parasites are still lingering, in a latent condition, within the system; for the patient cannot really be considered as cured till the last of these is put an end to. The length to which this chapter has attained may be justified by the fact that the universality and the extent of the mischief wrought by malaria in tropical climates renders the subject by far the most important of all in connection with the preservation of health in the tropics; and the writer trusts his readers may be moved to do as much as they possibly may to preserve themselves and their neighbours from the havoc wrought by this insidious disease, for without an informed and intelligent public opinion to back them, no possible efforts on the part of sanitary officials and medical men can be expected to exercise any great or lasting effects on the prevalence of the disease. CHAPTER VIII. On the Prevention and Treatment of Certain of the more Common Tropical Diseases. Although the main essentials of domestic sanitation have already been dealt with at some length, and incidental mention has necessarily been made of their bearing on the avoidance of particular maladies, it appears desirable to devote a few pages to the separate consideration of the avoidance of some of the more common tropical diseases. Some apology may be necessary for the inclusion in the following remarks of some brief references to medical treatment, but it is difficult to keep absolutely distinct the subject of prevention and cure in a popular work, and while there is no desire to convert this little book into a treatise on family medicine, it is thought that a few words on the subject of remedial treatment may not be out of place, especially as most of the writers that treat of this subject popularly, from the tropical point of view, are hopelessly out of date.
