THE CAPILLARY SUPPLY IN NORMAL AND HYPERTROPHIED HEARTS OF RABBITS.

1. During normal growth of the rabbit heart, muscle fibers enlarge, and the capillaries multiply so that a relatively constant capillary supply per unit of tissue is maintained from the time of birth to maturity. 2.

EFFECTS OF INSULIN ON THE WEIGHT OF THE RABBIT'S SUPRARENAL GLANDS.

There is no gross hypertrophy of the adrenals in rabbits after long continued, daily doses of insulin.

THE KINETICS OF STARVATION : II. THE LOSS OF WEIGHT IN PIGEONS SUBSISTING ON WATER ALONE.

1. The loss of weight in pigeons subjected to prolonged starvation on water alone may be accurately represented by an appropriate form of the law of autocatakinesis. 2.

THE KINETICS OF STARVATION.

1. The relative weight loss of pigeons on starving rations may be represented by a simple modification of the law of autocatalysis. 2.
