68 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTUR AL SOCIETY. 



Mr Ealand describes the Gipsy Moth, San Jose Scale, Hessian 

 Fly, Mediterranean Fruit Fly, and Vine Phylloxera. 



In the chapter "Insects and Human Disease" — a branch of 

 Entomology in which British workers hold a high and very 

 honourable place — the author mentions Mosquitoes and Malaria, 

 Yellow Fever and Stegomyia, Tsetse Flies and Sleeping Sickness, 

 Phlebotomus and Three-Day Fever, the Flea and Plague, and 

 also Ticks. Then diseases of stock, as related to Insects and 

 Arachnids, receive attention, and there are other chapters on 

 Beneficial Insects, Insect Pests in Houses and Insect Control. 



Mr Ealand covers in this book a wide field, and certainly succeeds 

 not only in conveying a mass of interesting general information 

 but also in impressing the reader with the very important part 

 which insects play in relation to man. The book can be 

 cordially recommended. The Class Insecta is one of the 

 dominant Classes of animals, and by adaptation to environment 

 insects have very successfully solved for themselves their problem 

 of existence. This is now so well recognised that almost every 

 country in the world has its official entomologists. The literature 

 of the subject increases with leaps and bounds, so that it is no 

 longer an easy task to give a general account. 



The book is illustrated. While some of the figures are good, 

 others have been drawn from poor specimens; a number could 

 be improved, e.g. the figure of the Sheep Ked is poor, the egg of 

 the Horse Bot Fly is represented upside down, and the drawing 

 of Psoroptes equi is wrong. R. Stewart MacDougall.
