II. Besides the detailed examination of examples of the various 

 groups it is important to know something of the general appearance, 

 habits, etc., of the largest possible number of animals. For this pur- 

 pose systematic collecting on land, in fresh-water, and by the sea-shore 

 is essential. Zoological gardens and public aquaria should also be 

 visited as well as the zoological department of a well-arranged Museum, 

 in which unknown forms may be identified and the whole subject of 

 classification firmly impressed upon the mind. Special attention should 

 also be directed to the illustrations of general and philosophical zoology 

 to be found in the best modern museums. 



There are, however, many rare animals which cannot well be seen 

 alive, and which lose their form and colour when preserved. It is 

 therefore advisable to have access to books illustrated by accurate 

 figures, coloured if possible, of the rarer and less familiar forms. The 

 following works will be found useful from this point of view.
