How to Keep Fit in the African Tropics. A Pamphlet for the use of Soldiers on 

 the Insect Pests and Diseases likely to be met with by an Expeditionary 

 Force operating in British East Africa. Printed for His Majesty's Stationery 

 Office by Harrison & Sons, St. Martin's Lane, W.C. (Pp. 46.) 



One of the very best little text-books for soldiers ever published ; but it will 

 apply not only to the African tropics but the tropics at large. The author 

 (who is one of our most distinguished men of science, though his name does 

 not appear in the book) has a most excellent but easy style. The pamphlet 

 begins with a good introduction followed by biographical and climatic 

 information. Then there is a very good brief account of insect pests, followed 

 by a similar one of the diseases, fevers, worms and diseases of animals 

 occurring in warm climates. Although the pamphlet could almost be put in 

 the waistcoat pocket it contains most of the matter generally laid out more 

 diffusely in bulky text-books of tropical medicine. It will be useful not only 

 to soldiers but also to medical officers who have not been through a course 

 of tropical medicine. — R. R.
