Mr. Cottincwoop Ineram showed some very) fine slides, 
kindly lent by Mr. W. J. Palmer, of various British birds 
with nests and young, mostly taken at Dungeness. Of 
special interest were those of (i.) a Linnet’s nest on the 
ground amongst the grass, (ii.) a male Reed-Bunting on the 
nest, and (iii.) a Nightjar sitting ou eggs on Dungeness 
beach. 
Surgeon-Commander G. Murray Levick, R.N., gave an 
interesting account, illustrated by magnificent photographic 
slides, taken by himself, of the habits of the Adélie Penguin 
(Pygosceles adelie) as observed during the British Antarctic 
(‘ Terra Nova’) Expedition. 
The birds commenced to arrive at the rookery at Cape 
Adare in the middle of October (1911). One arrived on the 
13th and by the 17th a large number had arrived and a loug 
line of Adélies could be seen across the sea-ice, tailing out 
in snake-like fashion as far as the horizon. 
Mating commenced after the birds arrived at the rookery, 
the hen establishing herself on an old nest or scooping out a 
hollow in the ground and waiting for a cock to “ propose.” 
Without cessation the stream of arrivals continued until 
October 30th, by which time the rookery was crammed with 
birds to the number of some three-quarters of a million, the 
occupants spreading right up the cliff of Cape Adare and 
a large colony establishing itself at the summit at 1000 
feet above the sea. 
During the mating-period severe fighting took place’ 
between the cocks for the possession of the hens, and during 
the first days of wedded life a cock was only able to keep his 
mate by dint of constant vigilance and many battles ; but 
after the eggs were laid comparative peace reigned in the 
rookery, and each couple remained perfectly faithful to one 
another. 
The nests of this species are all built of pebbles collected 
by the cocks, who are only too ready to rob each other’s 
-nests. The incubation-period appears to be from 30 to 37
