We teach the children to say “about two hundred,” because there is not always the same number of bones in the body.  In some parts two or three bones unite and form one bone.  For example:  the breastbone of a child is made up of eight pieces; some of these unite as it becomes older, so that when fully grown it has but three pieces in this bone.

[1] The teeth are not bone, but a kind of soft, bone-like substance, called dentine.  Common ivory is dentine.

Formulas for the lessons on the organs of sense.

1. The Eyes.—­My eyes are to see with.

My eye is like a ball in a deep, bony socket.  The black circle in the centre is the pupil or window of my eye; the colored ring is the iris or curtain; the white part is the eyeball.

My upper and lower eyelids cover and protect my eyes.

My eyebrows are for beauty, and keep the perspiration from rolling into my eyes.

My eyes are washed by teardrops every time I wink my eyelids.

2. The Ears.—­My ears are to hear with: 

  the rim of my ear,
  the flap of my ear,
  the drum of my ear.

The drum of my ear is protected by a fence of short, stiff hairs, and by a bitter wax about the roots of these hairs.

3. The Nose.—­My nose is to smell and breathe with; it is in the middle of my face: 

my two nostrils, the bridge of my nose, the cartilage, the tip of my nose.

My nostrils lead to a passage back of my mouth through which I breathe.

The cartilage separates my nose into two parts.

4. The Mouth.—­My mouth is to speak, eat, and breathe through: 

  my upper lip,
  my lower lip.

In my mouth are: 

my tongue, my lower teeth, my upper teeth, my lower teeth, and my upper and lower jaws, covered with flesh called gum.

5. The Teeth.—­My teeth are used in eating and talking.
