Frog-Fish of Surinam, a very singular animal, of which a figure is given by Mr Edwards, Hist. of Birds, Vol. I. There is no specimen in the British museum, nor in any private collection, except that of Dr Foster-gill. It was brought from Surinam in South America.—Frogs, both in Asia and Africa, according to Merian, change gradually from fishes to frogs, as those in Europe; but after many years revert again into fishes, though the manner of their change has never been investigated. In Surinam these fishes are called jakjes. They are cartilaginous, of a substance like our muskela, FRO

Frome, musketa, and exquisite food: they are formed with regular vertebrae, and small bones all over the body divided into equal parts; are first darkish, and then grey: their scales make a beautiful appearance. Whether this animal is, in its perfect state, a species of frog with a tail, or a kind of water lizard, Mr Edwards does not pretend to determine; but observes, that when its size is considered, if it should be deemed a tadpole at first produced from spawn, and in its progress towards a frog, such an animal, when full grown, if it bears the same proportion to its tadpole as those in Europe do, must be of enormous size; for our full grown frogs exceed the tadpoles at least 50 times.
