to the proof.--BELL'S _Anatomy_. Animal sensibility would be
inconvenient; it is therefore not to be found except in diseased bone,
where it sometimes exhibits itself too acutely.--TODD'S _Cyclopedia of
Anatomy_.

19. Is the constitution of bone the same in animals as in man?
_Ans_.--The bones of quadrupeds do not differ much from those of man.
In general they are of a coarser texture, and in some, as in those of the
elephant's head, we find extensive air cells.--TODD'S _Anatomy_.

THE MUSCLES.

"Behold the outward moving frame,
Its living marbles jointed strong
With glistening band and silvery thong,
And link'd to reason's guiding reins
By myriad rings in trembling chains,
Each graven with the threaded zone
Which claims it as the Master's own."
