In the correct position, the shoulders should be set squarelyacross the back, so that they are flat and the shoulder blades donot protrude. A vertical line drawn upward through the roundof the shoulder should fall within the ear or behind it, theexact point varying in different individuals. The hollow in theback should not be excessive, — a fault that may be detected, I02. Gainsiorough Plate XII. — The Morning Walk. Squire Hallett and his Wife. {From the collection of Lord Rothschild.

The feet should have the toes directedstraight ahead, and the weight should fall on the middle or for-ward part of the foot. The normal chest in an adult is much broader (from side toside) than it is deep (from front to rear), the index, or pro-portion of depth to breadth, being from seventy to seventy-twoper cent.
