The authors show that, whore both are present, the function of the 
falso, or “ ventricular,’’ vocal cords is to provent air from leaving 
the thorax, while that of the true cords is to keep it out ; and that in 
those Mammals, such as man, the cats, bears, &c., in which the anterior 
limbs are used, not only for progression, but for striking, climbing, or 
performing other more or less delicate offices, and in which, therefore, it 
is necessary for the thorax to be at times fixed and rigid, the ventricular 
cords, which prevent the exit of air, are strongly developed ; while in 
those, such as the Ungulates, which are purely quadrupedal, they are very 
small or absent.
