56 “TERRA NOVA” EXPEDITION. 
to study Dr. Wilson’s more thorough and more scientific pages. Reference may also 
be made to :— 
‘“ Report on the Collections of Natural History made in the Antarctic Regions 
during the Voyage of the ‘Southern Cross.” (British Museum, 1902.) 
III. Extracts from the private Diary of the late Nicolai Hanson. 
IV. Aves, by R. Bowdler Sharpe. 
Information is here meagre, owing to the sad death of the Expedition’s zoologist, 
N. Hanson, at an early date. His work was carried on by Mr. H. Evans, another 
member of the Expedition, but both Hanson’s and Evans’ notes were handed over to 
the commander, and have not been published. Mr. Bernacchi also contributes some 
notes in this volume. 
“To the South Polar Regions.” (Hurst & Blackett, 1901.) 
Beginning on page 190, Mr. Bernacchi tells us a good deal about Adélie 
Penguins, some of his observations differmg somewhat from those of the present work. 
The photographs are very interesting.

These notes are brief and incomplete. 
“ The Penguins of the Antarctic Regions.” Smithson. Rep. for 1912, pp. 475-482, 
with plates 1-9 (1913). 
Here Dr. Louis Gain, the zoologist of Dr. Charcot’s Expedition (1908-1910), gives 
a brief sketch of the Adélie Penguin’s habits. He proves that some at any rate, 
and probably all, return to the same rookeries year after year to breed. This is of 
great importance, as it definitely settles the question of the penguins’ “sense of 
direction,” which alone guides them over their hundreds of miles of migration. It 
is surprising that he names Lobodon carcinophagus and Leptonychotes weddelli as 
formidable enemies of the Adélie Penguin. His photographs are particularly good. 
The subject is also treated by the same author under the title :— 
“ La Vie et les Meurs du Pingouin Adélie.” 
1913, pp. 501-521, figs. 1-13 (1914). 
With the exception of Dr. E. A. Wilson’s account, referred to above, perusal of 
these publications, as well as the casual references to Pygoscelis adeliw to be found 
among the other works dealing with antarctic exploration, conveys the impression that 
the writers have either lacked opportunity, or have not done full justice to the habits 
of these wonderful birds.
