Note on the Carnivorous Propcmity of Mollush. Seeing in a late number (Zool. 

 201), a notice of snails devouring insects, perhaps I may mention that about a week 

 ago my attention was attracted by seeing a large earth-worm writhing about in intense 

 agony. On looking in the grass I found that a large black snail was devouring the 

 worm ; in the course of half an hour, during which time I watched it, about half of the 

 worm was devoured by its greedy adversary. A friend of mine also tells me that he 

 had seen a snail devouring a beetle, which had accidentally been crushed to death on 

 the garden walk. — Robert John Bell ; Mickleover House, Derby ^ July 10, 1843.
