DEATH OF SHEEP FROM WORMS IN THE STOMACH. 525 
It would be out of place here to enter upon the question, 
how these remains became thus deposited. By some it is 
thought that the animals furnishing them were once natives 
of those places in which their bones have been discovered, 
but that the climate and other circumstances have so changed 
since as no longer to enable them to live there; by others, 
that by the waters of the general deluge wild and other 
animals were driven together into these caverns, as places of 
refuge, and there drowned. Confirmative of this latter view 
is the fact, that among the fossil bones of animals have been 
found many of such as are now altogether extinct, especially 
of the larger herbivora. “Jt appears that the devastating 
effects accompanying the vast change which this planet then 
underwent were so extensive, that not only some species of 
quadrupeds were entirely removed of some genera, such as 
the elephant, rhinoceros, and hippopotamus, of which other 
species still remain, but that other genera, as mastodon, palceo- 
tJierium , and anoplotherium, were completely annihilated through 
all their species.” 
In reference to these accumulations, Professor Ansted says: 
—“ On land, near England, then slowly emerging out of a sea 
traversed by icebergs, having a climate greatly varied, but 
on the whole warm, there roamed, at a very distant period, 
elephants and rhinoceroses, large deer and musk oxen, gigan¬ 
tic bears, tigers and hyaenas, and numerous smaller animals, 
many of which are still common. In the rivers of this land, 
or in pools and lakes there, were many species of hippopota¬ 
mus, and we may safely conclude that there was a corre¬ 
sponding vegetation. It could hardly have been a small 
tract to support these gigantic quadrupeds; it is more likely 
to have been a fragment of one much larger which had been 
partly submerged. 
“The hyaenas and the bears then occupied caves in the lime¬ 
stone rocks as dens, and carried thither their prey. The 
British islands formed no separate group, and the whole 
Continent of Europe was probably but an archipelago.”

We transcribe the following correspondence from the 
Mark Lane Express, as it will tend to give greater pub¬ 
licity to the circumstance of entozoic diseases being greatly 
on the increase, and more especially among cattle and sheep. 
We hope ere long to take this subject up, and to lay before
