PART III.

FORMULA FOR THE LESSON ON THE BONES OF THE BODY.

1. My bones are hard; they make my body strong. There are about two hundred bones in my body.

2. The bones of my head are

my skull and my lower jaw;

my face has fourteen bones; my ear has four small bones; at the root of my tongue is one bone.

3. The bones of my trunk are

my spine,

my ribs,

my breastbone,

my two shoulder blades,

and my two collar bones.

4. My upper arm has one bone; my fore-arm has two bones; my wrist has eight bones; from my wrist to my knuckles are five bones; my thumb has two bones; each finger has three bones, making nineteen bones in my hand.

5. My thigh has one bone; my lower leg has two bones; my knee-pan is the cap which covers and protects my knee; in my foot, near my heel, are seven bones; in the middle of my foot are five bones; my great toe has two bones; each of my other toes has three bones; making twenty-six bones in my foot.

QUESTIONS FOR THE FORMULA.

1. Tell about your bones.

2. Tell about the bones of the head.

3. Tell about the bones of the trunk.

4. Tell about the bones of the arm and hand, beginning with the upper arm.

5. Count the bones of the hand.

6. Tell about the bones of the leg and foot, beginning with the thigh.

1, 2, 3, 4, 5, the bones of the palm of the hand.

6, 7, the bones of the thumb.

8, 9, 10, the bones of the first or fore-finger.

11, 12, 13, the bones of the second or middle finger.

14, 15, 16, the bones of the third or ring finger.

17, 18, 19, the bones of the fourth or little finger.

1, 2, 3, 4, the upper row of the bones of the wrist.

5, 6, 7, 8, the lower row of the bones of the wrist.

9, 10, the lower ends of the bones of the fore-arm.

11, 12, 13, 14, 15, the upper ends of the bones of the palm of the hand.

The bones of the wrist are so firmly fastened together that they are seldom put out of place. The upper row joins with the bones of the fore-arm, the lower with those of the palm of the hand.

EXERCISE FOR COUNTING THE BONES OF THE HAND.

FOR PRIMARY CLASSES.

1. Close both hands.

2. Raise the forefinger of the right hand, as the index or pointing finger.

3. Place the index finger upon the lower thumb joint of the left hand.

4. Draw the index finger down to the wrist, over the bone between the thumb knuckle and the wrist, and count "One."

5. Place the index finger on the knuckle of the first finger.

6. Draw the index finger down to the wrist, over the bone leading from the first finger to the wrist, and count "Two."

7. So on, for each of the three other bones of the hand. Repeat until no mistake is made in touching or counting.

II.

1. Raise the thumb, and place the index finger of the right hand on the middle of the upper part of the thumb for bone "Six"; then

2. On the lower part of the thumb for bone "Seven." Repeat from the beginning, until the children can touch and count each bone properly.

III.

1. Keep the thumb erect; raise the first finger of the left hand.

2. Place the index finger on the bone between the tip and the first joint of the first finger for bone "Eight."

3. Between the first and middle joint for bone "Nine."

4. Between the middle and third joint for bone "Ten." Review, from the beginning, until the class can touch and count every bone as directed.

IV.

1. Keep the thumb and forefinger erect; raise the second finger and touch, as in the lesson on the first finger bones, "Eleven," "Twelve," and "Thirteen." Review.

2. Proceed in the same manner for the third and fourth fingers, always beginning with the bone nearest the tip of the finger, and touching that at the lowest part last.

If the exercise has been properly performed, every child will say "Nineteen" as its index finger touches the lowest bone of the little finger, and all the fingers of every left hand will be outspread.

THE BONES

OF THE HEAD:
Skull	8
Face, including the lower jaw	14
Tongue	1
Ears	8
	——
	31
OF THE TRUNK:
Spine	24
Ribs	24
Breastbone	8
Shoulder blades	2
Collar bones	2
	——
	60
OF THE UPPER LIMBS:
Upper arms	1 x 2 = 2
Fore-arms	2 x 2 = 4
Wrists	8 x 2 = 16
Hands	19 x 2 = 38
	——
	60
OF THE LOWER LIMBS:
Thighs	1 x 2 = 2
Knee-pans	1 x 2 = 2
Lower legs	2 x 2 = 4
Feet	26 x 2 = 52
	——
	60

Total, 211, not including the teeth.[^[1]]

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.
