62 Prince asked for an explanation of this apparent miracle.

"Your Royal Highness," said Fox, "chose, of course, the shady side of the way as most agreeable. I knew that the sunny side would be left for me, and that Cats prefer the sunshine."

Cats usually, but not always, fall on their feet, because of the facility with which they balance themselves when springing from a height, which power of balancing is in some degree produced by the flexibility of the heel, the bones of which have no fewer than four joints. Cats alight softly on their feet, because in the middle of the foot is a large ball or pad in five parts, formed of an elastic substance, and at the base of each toe is a similar pad. No mechanism better calculated to break the force of a fall could be imagined.

A Cat, when falling with its head downwards, curls its body, so that the back forms an arch, while the legs remain extended. This so changes the position of the centre of gravity, that the body makes a half turn in the air, and the feet become lowest.

In the inside of a Cat's head there is a sort of partition wall projecting from the sides, a good way inwards, towards the centre, so as to prevent the brain from suffering from concussion.
