the open Air. For others he cannot be pofitive, 
as their Hiftory is little known. 
The Letter- writer premifes two Queftions; firft, 
Whether Fillies have any Ears? or, If the Gills ferve 
the fame Purpofe ? and anfwers pofitively in the 
Negative to both : And therefore concludes they 
cannot hear. But our Author afferts, that Snakes, 
Frogs, Chameleons, and others of the Lizard kind, 
a&ually hear, without any of the ufual external Ap- 
paratus of Hearing. For though they want the Auri- 
cles and Ears, yet have they auditory Pafiages, by 
which Sound is convey’d, and even internal Organs, 
to which the Meatus auditorius reaches. But our 
Author farther afferts, that all the Whale-kind, and 
in general fuch Fifhes as have Lungs, have like wife 
a Meatus auditorius , and the internal Organs of 
Hearing 5 and appeals to a public Piffe&ion of a 
Porpoife, and another Fifh of the Whale-kind, made 
by himfelf; in which the Os petrofum , with the 
other Parts of thefe Organs, had been feparately 
fhew’d ; and calls in the concurrent Teftimony of 
Dr. Tyfon , in his Anatomy of a Porpoife. 
Thus having fatisfied us about fuch Fifh as have 
Lungs, he goes on to confidcr the cartilaginous 
Species, fuch as the Skate, Ray, and kind of Lam- 
prey, which have Organs of Generation, and copu- 
late like Brutes 5 yet exclude the Foetus while yet in 
the Egg-State : And this from Analogy, that thefc y 
and in general all other Fifh, as they have Organs 
which ferve them for Lungs, fo they may have what 
anfwers in others to the Apparatus of Hearing. 
In Proof of this he afferts, that all Kinds of Fifh 
but thefe which have Lungs, are always found to ' 
have
