10 SECRETS OF ANIMAL LIFE 



Adelie species at least than any previous observer. 

 The work of Dr. Edward A. Wilson, whose un- 

 timely death was such a loss both to science and art, 

 remains a model of accuracy and thoroughness, but 

 Dr. Levick has gone further. He has previously 

 written a delightful popular study of the social 

 habits of the Adelie penguins (Heinemann, 1914) ; 

 what we have before us now is an excerpt (1915) 

 from the first volume of the British Museum Report 

 on the zoological discoveries of the " Terra 

 Nova " Expedition. It is entitled Natural History 

 of the Adelie Penguin, and is illustrated with 

 twenty-one remarkable photographs. It is a study 

 which any naturalist might be proud of, and it 

 shows the author to be an observer of the first rank. 

 The observations appeal not only to those who are 

 keen on birds, but also to those who are interested 

 from the philosophical side in the deeper problems 

 of natural history. " You of any well that springs," 

 said Meredith, " may unfold the heaven of things," 

 and it is extraordinary how " far ben " into biology 

 Dr. Levick's careful study leads us. 



Towards the middle of October, a single Adelie 

 penguin was seen on the rookery at Cape Adare. 

 Two days afterwards there were two, and next day 

 about a score, and next day "as we looked across 

 the sea-ice to the northwards, we could see a long 

 line of Adelies approaching, tailing out in snake- 

 like fashion, as far as the horizon." This is the first 

 picture, the return of the penguins to their birth- 

 place. Dr. Louis Gain of the Charcot Expedition
