Want to Measure the Baby’s Horse Power? Here’s the Way

Dr. John R. Murlin of Cornell University Medical college has devised an apparatus which causes a baby to record its horse power, says Popular Science Monthly. Horse power, is used in this sense merely as the expression of a unit of energy. A baby unconsciously writes the story of its energy by means of Its pulse and its breathing. A small cuff is attached to the left leg of the infant above the knee. From thifc cuff a tube leads to a glass connection, passing through the wall of the incubator and finally to a T-tube on the top of the incubatdr. One limb of this tuhe passes te ( an air-pump and the other to another T-tube. To the second T-tube K wercury pressure gauge (Tnnnometert te connected by one limb and a pressure-bottle to the other.

leads to a record! ngd rum. Thus with each, pulse the baby makes a record. Oddly enough, the fattest baby produced the smallest degree of horse power. While sleeping the babies produced an average of .004 of a Horse power. It was determined that the normal heat production of recently fed. sleeping babies between two months and one year of age is .00 horse power.
