a moderate-sized crab busy with something under a ledge of 
rock. To confirm my suspicions, I broke out a Pholas away 
from the pool, so as not to stir up the mud, and dropped it 
into the water, when out rushed three or four crabs, and the 
one there first seized the Pholas and scurried away, holding 
the shell up in its fore-claws. 
Having often heard wonder expressed that the Pholas could 
excavate holes into rocks of varying hardness with so fragile 
a shell, I tested the cutting hardness of the shell. I found that 
with the rasplike sides of a valve I could scratch and wear into 
marble and calcite, and also scratch fluor-spar. Evidently, 
therefore, the shell is sufficiently hard to wear into wet rocks.

Volume XLV. of the North Staffordshire Field Club’s Annual Report 
and Proceedings for 1910-11 contains valuable reports on the club’s year’s 
work, in the various branches. There are also a number of archeological 
papers bearing upon the club’s sphere of investigation. 
‘Shipley Glen: An explanatory Outline of its Physical Features for the 
interested lover of our country’, is reprinted from ‘The Bradford Scientific 
Journal,’ by Mr. W. P. Winter, B.Sc. The pamphlet is well illustrated by 
a map and views. It should have been dated. 
Part VIII. of Major Barrett Hamilton’s ‘ History of British Mammals’ 
deals with the hedgehog, the common shrew, and the lesser shrew. These 
are referred to in the same thorough way as those in previous parts. There 
are several illustrations, including an admirable coloured plate of house 
mice. 
Part LX XXIII. of the Yorkshire Archeological Journal contains an 
illustrated list of the Anglian and Anglo-Danish Sculpture in the East 
Riding ; from which, however, the record of the part of the pre-Norman 
cross found at Patrington two or three years ago, is omitted. Messrs. 
W. H. St. John Hope and H. Brakspear give an excellent plan and des- 
cription of Jervaulx Abbey, in the same publication. 
We are not aware that nightingales have been recorded singing so far 
north as Aberdeenshire, but in case our Scottish friends care to have such 
a record, we give the following extracts from Miss Florence L. Barclay’s 
book, ‘ The Rosary,’ the locality referred to being Deeside, Aberdeen- 
shire :—‘ The nightingales filling the woods and hills with soft-throated 
music,’ and later on in the same chapter, ‘ Sweet, sweet, sweet thrill, sang 
a nightingale in the wood’; and again, ‘ Two nightingales, in distant 
trees, sang alternately, answering one another in liquid streams of melody.’
