Greyhounds run Wild. 
In May 1814 I saw, in the Jardin des Plantes, at Paris, two, or 
perhaps three, animals, which I should have declared, on my oath, 
to the best of: my knowledge and belief, to be neither more nor less 
than wire-haired Scotch greyhounds, which were labelled ‘ Loups 
des Pyrénées.” Now I know, of my own knowledge, that the roads in 
the seat of war were at that time so encumbered with dead baggage- 
animals, that the sporting dogs of the English officers took the 
opportunity of being independent of their masters for food, to turn 
wild and live upon the country. I remember riding towards half a 
dozen of them feasting on a dead mule, when they with one accord 
formed line between me and their prey, and advanced against me 
with one disciplined howl; insomuch that I retired, lest they should 
proceed to try to add me and my horse to their larder. 
It has within these few days occurred to me as possible that some 
ingenious Frenchman, between joke and earnest, may have seized on 
a portion of these dogs, and sent them to Paris with a “ Voila 
les véritables loups des Pyrénées.”” I am sure what I saw were 
Scotch greyhounds, and nothing else. I remember that one or more 
of them was savage and ill-tempered, as dogs are given to be when 
shut up in cages. I remember seeing two Cuban bloodhounds in a 
cage at the Zoological Gardens, one of which was as savage as any 
hyena. I have a notion that dogs at large would have no difficulty 
in returning to the wild state if exposed to temptation. 
I have written to my son, who is at Pau, to ask himif he can throw 
any light on the point. He reports seeing young wolves brought in 
to Pau as a show.—T. P. T. 
On the Perforating Bryozoa of the Family Terebriporide. 
By P. Fiscuer. 
The existence of perforating animals has been ascertained in nearly 
all the classes of Invertebrata—Mollusea, Annelida, Echinodermata, 
Spongiaria, &c.; the vegetable kingdom likewise presents us with. 
examples of Protophyta hollowing out their residence in shells and 
stones. Perforation and, consequently, the destruction of the per- 
forated bodies are therefore the effects of a great law of nature. By 
the side of the creatures which accumulate masses of calcareous 
polyparies, and of those of which the shells strew our shores and 
cover the bottom of the sea, nature has placed other organisms, 
smaller but not less powerful in their effects, which restore to the 
ocean the elements which have been drawn from it. 
Among the Bryozoa the existence of terebrant cells is almost a 
new fact. It was known that some Lepralie and Cellepore slightly 
alter the surface of the shells to which they attach themselves ; 
but before the discovery of Alcide d’Orbigny, no one had ever seen 
them lodged in the very interior of the shells.
