Biological Atlas. By D. and A. N. M< Alpine. Edinburgh and 



London, W. and A. K. Johnston. 



The authors intend this to be a guide to the practical study of 

 plants and animals, adapted to the requirements of the London 

 University, Science and Art Department, and for use in schools 

 and colleges. They have succeeded in making a very useful work, 

 exhibiting in a somewhat diagrammatic manner typical specimens 

 of the leading life forms, the characters on which their systematic 

 positions are based, and the main points in their life history. The 

 work, as far as it goes, represents the present stage of biological 

 science. By the use of colour, and by employing the same colom 

 for corresponding systems or organs in the' different life forms, 

 great plainness is secured. The Atlas will be a useful com] 'anion 

 to any biological hand-book, but its chief use will be in the 

 laboratory or dissecting-room, as designed by its authors. The 

 letterpress consists of little more than explanations of the illus- 

 trations, but it is expressed and arranged in such a manner as to 

 convey, or perhaps rather rccal, a large amount of information to 

 the student. W. C
