76 THE LIFE OF THE MOLLUSCA 
confinement through two summers, became torpid in 
October, 1851, and was found to be dead in May, 
1852. This specimen (Plate XIII., Fig. 34) was 
figured by Dr. S. P. Woodward in his “ Manual of 
the Mollusca.” The Rev. A. H. Cooke collected 
examples of this species in Egypt in 1904, and kept 
them ina tin box without food. In January, 1912, 
ten individuals were still alive, but only three sur- 
vived by the following March, although food had 
been supplied to them. 
There is a record in the Philosophical Transac- 
tions for 1774 of some Snails that had lain by ina 
cabinet for more than fifteen years resuscitating on 
being placed in water ; but, despite the detailed state- 
ment and assertion that no error was possible, the 
narrative does not seem credible. 
Such dainty morsels as molluscs are naturally 
relentlessly pursued and devoured. Leaving man 
out of the question, many animals from the Whale 
to the Mouse prey on them. 
A Monkey (Macacus cynomolgus) has been seen to 
feed on Oysters, the shells of which he broke open 
with a stone. The Right Whale devours enormous 
quantities of Pteropoda with other pelagic creatures; 
the Cachalot, Grampus, and other Cetacea, devour 
Cuttlefish. The walrus digs Bivalves out of the 
silt on the sea-floor with his tusks, and eats them.
