FROGS. 421 
brooks, muddy ditches, marshy grounds, and other watery 
places ; in summer in corn fields and pasture land. Frogs 
have two bladders, one on each side of the mouth, which 
they fill with wind, and hence proceeds their voice. 
When they croak they put their heads out of the water, or 
else they eould not be heard. The hinder legs of the Frog 
are much longer than the fore ones, to help them in those 
repeated and extensive leaps which they make to avoid 
danger. The whole of the body bears a little resemblance 
to some of the warm-blooded animals, principally about 
the thighs and the toes. The frog is extremely tenacious 
of life, and often survives the abscission of its head for se- 
veral hours. It is supposed that Frogs spend the whole 
winter at the bottom of some stagnant water, in a state of 
torpidity. 
There are several species of the Frog ; they are all ovi- 
parous, and the eggs are gelatinous. The Edible Frog 
is the species used in France and Germany for food ; it is 
considerably larger than the common kind, and though 
rare in England, it is very plentiful in France, Germany, 
and Italy. Its colour is olive green, marked with black 
patches on the back and on its limbs with transverse bars 
of the same. From the tip of the nose, three distinct 
stripes of pale yellow extend to the extremity of the body ; 
the middle one slightly depressed, and the lateral ones 
considerably elevated. The upper parts are of a pale 
whitish colour, tinged with green, and marked with 
irregular brown spots. These creatures are brought from 
the country, thirty or forty thousand at a time, to Vienna, 
and sold to the great dealers, who have froggeries for 
them, which are pits four or five feet deep, dug in the 
ground, the mouth covered with a board, and, in severe 
weather, with straw. In the year 1793, there were but 
three great dealers in Vienna, by whom those persons 
were supplied who brought them to the markets ready for 
the cook, as only the legs and thighs are eaten, and these
