Deep in the heart of a chicken, which was taken eight years ago from a bird that never lived, works a strange dauntless force which apparently only needs a little artificial nourishment to keep it going for ever.
The heart, which was taken from an embryo bird, lives in a glass jar in the laboratory of Dr. Alexis Carrel, head of the Rockefeller Research Institute of New York. It is surrounded by an_ antiseptic solution which seemingly satisfies all its needs in life, for the organ, after all these years, is still hale and hearty. In fact, it is several times larger than when it was first bottled and is continually throwing out fresh tissues.
After the 3rd year of the experiment. Dr. Carrel came to the conclusion that the connective tissue showed greater activity than ever and was no longer subject to the influence of time. He adopted the theory that, excluding accidents, connective tissue cells may pro: pagate indefinitely. During the several years of Dr. Carrel's absence on war service in France the heart remained untended in its bottle. Careful examination now shows it still beats and adds con-finally to its tissues.
