it is 44°9; and finally for 1858, only 39°3. It is to be said, however, 
that this result is not confirmed by observations meee or at least is 
not evident from them.—JL’/nstitut, xxvi, 271, 858.

its literary, scientific or artistic merits. e aquarian naturalist will find

of England. We cite a few pa eg hi from the work :— 
“ Arenicola Piscatorum— The eer visitor to the sea-coast 
must have remarked certain sa ta A the shore, near low-water mark, 
almost entirely goneerd: with little pyramids or eke formed by coils 
of san astings, as they are called, of worms. All these 
little heaps are fs by an animal lurking at a considerable depth 
beneath the surface, named in scientific language Arenicola piscatorum, 
and known by fishermen, who find in it a valuable bait, as the Lug-worm 
or the pig There can never be any difficulty in procuring specimens
