M. Well, Willie, now you have done looking at it--which do you call the principal parts?

W: I should think that the Head must be one. What would it be without that! Then the middle part—the body, or the Trunk as it is called—is another principal part; and then, what is left? Why, there are legs and arms remaining, that is all—they are called Limbs. So, that there are three principal parts, —

(1.) The Head,
(2.) The Trunk,

(3.) The Limbs.
I suppose we shall learn of one
of these parts at a time. May we

-the shock would produce the same “jarring” of the vertebræ against each other—but, in an upward direction — from the bottom of your spine to the top ; and it would produce a very bad effect on your brain.

Saw you e'er such comic faces ?
Now like learned judge sedate,
Now with nonsense in his pate.
Look now at him. Slily peep,
He pretends he is asleep-
Fast asleep upon his bed,
With his arm beneath his head.

Ha! he is not half asleep,
See, he slily takes a peep!

Cracks as fast as e'er he can:
