HINTS TO TRAVELLERS. 
A mixture containing fifteen grains of bromide of soda, and five grains 
of antipyrine to one ounce of water, is often of great value. The first 
dose should be given immediately the patient is in bed, and may be 
repeated every six hours if required. 
Whitla states that the best of all remedies is bromide of ammonium. 
It should be given in twenty grain doses for a day or two before 
embarking. Morphia may be found necessary; a third of a grain may 
be injected under the skin of adults, but it should on no account be 
given to children. 
I have found that three or four drops of chloroform, dropped on to loaf 
sugar and sucked, often prevents vomiting. 
Those who are vomiting severely should take plenty of hot water or 
milk so as to prevent them from straining on an empty stomach. 
Prickly Heat. 
Prickly heat is frequent in the tropics. It is due to free sweating, and 
causes intense heat and itching. 
The diet should be light, very little animal food, and no alcohol. The 
skin should be kept clean, cool, and dry, and light linen or cotton 
garments worn next the skin instead of flannel. 
The annoying heat and itching are relieved by the application of 
carbolic solution to the skin (about a tablespoonful of carbolic acid to 
two pints of water). A dusting powder of starch, arrowroot, or oxide of 
zinc often does good. 
A lotion made by squeezing three or four limes into a pint of water 
may be applied, but this often causes for the moment a good deal of 
smarting. Goulard lotion does good in many cases. It may be 
necessary to give twenty grains of bromide of potassium at night to 
procure rest. Bicarbonate of soda should be given three times a day in 
ten-grain doses. A good saline purge should always be administered at 
the beginning of an attack. 
Chilblains and Frostbite. 
Chilblains are usually found on the fingers or toes—after exposure to 
severe cold—especially when tight gloves or boots have been worn.
