vus AuMtoriuSy and the Undulation continued, firfl; by 
the Anfra^iuofities of the firft Cavity, and then by the 
Gyres and incurvated Lines of the fecond, fo that we 
may eafily account for the acute Senfation of Hearing, 
wherewith Elephants are faid to be endow’d : For as the 
Tame ones are moft exad in obeying their Maflers 
commands ; fo the wild Ones are foon aware of what 
Traps or Snares are laid to catch them, by the tremu- 
lous Motion convey’d to their Ear from the Cavous 
parts of the Earth, where the Pit into which it is expeded 
they fhould fall, is digg’d. It is eafy therefore to ex- 
plain whence the acucenefs of the Senfation of rhis A- 
nimal may proceed ; for as the Nervus OlfaPiorius has 
a large Space and Bounds wherein to be difpers’d, 
the two Cavities of the Prohofcis, which are both long 
and large, fo that fcarce any Columna aeris can enter 
them, but feme one or another of the Filaments of 
the Nervus OlfaPiorm difpers’d in thefe Cavities muft 
be toucht, whereby the Idea of fmelling mufl: be con- 
veyed to the Senforium commune in a more intenfe De- 
gree, and the Animal foon become fenfible of what- 
ever approaches that is noxious or naufeous to it, and 
thereby is taught hew to avoid it ; fo this Strudure, 
for a quick conveyance and long continuance of the 
Sound, is a great means both to make the Elephant 
foon receive the Sound and have a deep imprefTion 
of it.
