vi FROM NORTH POLE TO EQUATOR. 



father, who was never tied down to his paper, may often 

 have delivered the same matter in different forms according 

 to the responsiveness of his audience, abbreviating here, 

 expanding there yet to anyone who has heard him the 

 following pages will recall his presence and the tones of his 

 sonorous voice ; everyone will not only recognize in them the 

 individuality of the author of the Tierleben (Animal Life) 

 and Bird Life, but will learn to know him in a new and 

 attractive side of his character. For it is my father's lectures 

 almost more than any other of his works which show the 

 wealth of his experiences, the many-sidedness of his know- 

 ledge, his masterly powers of observation and description, 

 and not least his delicate kindly humour and the sympa- 

 thetic interpretation of animate and inanimate nature which 

 arose from his deeply poetic temperament. 



Therefore I send these pages forth into the world with 

 the pleasant confidence that they will add many to the 

 author's already numerous friends. May they also gain new 

 and unprejudiced sympathizers for the animal world which 

 he loved so warmly and understood so thoroughly; and may 

 they, in every house where the love of literature, and of the 

 beautiful is cherished, open eyes and hearts to perceive the 

 beauty of nature, the universal mother; then will the highest 

 and noblest aim of their author be achieved. 



So may all success attend these pages, may they receive 

 a joyful welcome, and wherever they gain an entrance may 

 they remain as a prized possession.
