 spiders are especially interesting. By a number of careful 

 experiments the Author discovered the mechanism of these 

 spiders* marvellous architecture. Much attention is given 

 to various species of ants and their organisations, while 

 nesting instincts of birds and emotional expression in 

 the leopard, besides other interesting topics are discussed 

 by this acute observer.
