against hers. I have noticed the same process in my own garden. 
Both my animals are, I believe, males. But I have observed one 
of them, when in an amorous humour, to strike the other several 
times in succession a sounding blow on its shell ; and this he does 
by suddenly withdrawing his head into his shell, so as to be out 
of harm’s way, and then as suddenly throwing his body forward 
by a sort of butting process against the shell of his fellow. This 
proceeding causes a very considerable, and indeed, comparatively 
speaking, quite a loud and resounding noise ; and at first sight 
these sudden and severe blows would appear to he more calculated 
to cause corporeal discomfort or injury than to excite affection. 
These very marked attentions are usually followed by the utterance 
of a quick and soft, or almost whining cry. 
I will only add that my Tortoises show an increasing familiarity 
and sense of being at home as years roll on.

Norfolk is remarkable among the counties of England, not only 
for the rarity of its feathered visitants, hut for the numbers of 
them which occasionally come to us. One year it is a plethora of 
Red-necked Grebes, another year it is Waxwings, and another 
Glaucous Gulls; in 1884 we had eighty Bluothroats ; in 1879 a 
hundred and fifty Pomatorhine Skuas; in 1870 sixty Little Gulls 
visited our shores never to return again. In 18G3 the number of 
Sand Grouse in Norfolk exceeded any other district of like size in 
Europe (‘ Ibis,’ 18G4, p. 201). It is now the Lapland Buntings
