A few books may be mentioned as specially suitable for those travelling in the countries with which they deal, such as ‘Hints for Residents and Travellers in Persia’ by A. R. Neligan, ‘Health Preservation in West Africa’ by J. C. Ryan, ‘Hygiene and Disease in Palestine’ by Masterman, and ‘The Epidemics of Mauritius’ by Anderson. Those who read German will find the ‘Gesundheitlicher Ratgeber für Auswanderer,’ issued under the auspices of the Institut für Schiffs- und Tropenkrankheiten in Hamburg, of considerable service, and if they intend visiting South America it is worth noting that from the same source a series of small books to guide the traveller in different parts of that continent will soon be forthcoming. This series will also include works on Mexico, Angola and Siberia. These German guides are obtainable from L. Friederichsen & Co., Hamburg. Persons who intend to travel should undergo a thorough medical examination, in order to ascertain if they are likely to be able to stand the fatigues, exposures and privations to which they will probably be subjected. [Illustration: FIG. 1.—DIAGRAM SHOWING SOME OF THE PRINCIPAL ORGANS OF THE BODY, AND THE COURSE OF THE MAIN BLOOD-VESSELS.] Most people of good constitutions and regular temperate habits can, with care, maintain a good state of health in the tropics, and many of those who have been by no means strong at home are able with some extra caution to do well even in the hottest climates. The intending traveller should attend a course of ambulance lectures in order to prepare himself for the responsibilities which he will have to undertake. As much time as possible should be devoted to discussing with some professional friend the uses, correct doses, and proper methods of prescribing and combining the drugs which are to be taken on the journey, and in becoming familiar with the position of the principal bones, vessels and other important structures of the human body. A traveller should understand how to use the clinical thermometer, how to twist or tie a bleeding vessel, how to use the hypodermic syringe and the syphon stomach tube. He should learn how to cleanse a wound, how to treat a case of snake-bite, and should know the best way in which to set a broken limb. Such things are not easily learnt from books, and experience alone will give the necessary skill and confidence. Many valuable lives have been saved by travellers who have fairly mastered the rudiments of medical and surgical treatment, and who have been able in an emergency to give the necessary drugs, administer an antidote, or to stop severe bleeding. The ideal traveller is a temperate man, with a sound constitution, a digestion like an ostrich, a good temper, and no race prejudices. He is capable of looking after details, _e.g._, seeing that drinking water has _really_ been boiled, and is willing to take advice from those who have made journeys in countries similar to the one in which he is about to travel.
