ADDENDA. 



Animals inclosed in Hock, d'c. 



Toads. — In 1770, a toad was brought to Mr, Grignon inclosed 

 in two hollow shells of stone ; but, on examining it nicely, Mr. G. 

 discovered that the cavity bore the impression of a shell-fish, 

 and, of consequence, he concluded it to be apocryphal. 



In 1771, another instance occurred, and was the subject of a 

 curious memoir read by Mr. Guettard to the Royal Academy of 

 Sciences at Paris. It was thus related by that famous naturalist: — 



In pulling down a wall, which was known to have existed up- 

 wards of a hundred years, a toad was found without the smallest 

 aperture being discoverable by which it could have entered. 

 Upon inspecting the animal, it was apparent that it had been 

 dead but a very little time; and in this state it was presented to 

 the Academy, which induced Mr. Guettard to make repeated in- 

 quiries into the subject, the particulars of which will be read with 

 pleasure in the excellent memoir we have just cited. 



"Worms. — Two living worms were found, in Spain, in the mid- 

 dle of a block of marble which a sculptor was carving into a lion, 

 of the natural color, for the royal family. These worms occupied 

 two small cavities to which there was no inlet that could possibly 

 admit the air. They subsisted, probably, on the substance of the 

 marble, as they were the same color. This fact is verified by 

 Captain Ulloa, a famous Spaniard, who accompanied the French 

 academicians in their voyage to Peru to ascertain the figure of 

 the earth. He asserts that he saw these two worms. 



Adder. — We read in the Afftches de Provence^ 17 June, 1772, 

 that an adder was found alive in the centre of a block of marble 

 thirty feet in diameter. It was folded nine times round, in a 

 spiral line. It was incapable of supporting the air, and died a 

 few minutes after. Upon examining the stone, not the smallest 

 trace was to be found by which it could have glided in or received 

 air. 



Crawfish, — Misson, in his Travels through Italy ^ mentions a 

 crawfish that was found alive in the middle of a marble in the 

 environs of Tivoli. 



Frogs. — M. Peyssonel, king's physician at Guadaloupe, having
