Immortal Life.

A famous French physiologist, Alexia Carrell, kept a chicken heart alive for about twenty-eight years! He incubated a chicken egg. The heart of the developing young chick was taken out and cut in pieces. These pieces, consisting of many cells, were transferred into a saline solution which contained minerals in the same proportion as chicken blood.

He changed this solution everyday, and he kept the chick’s heart alive for about twenty-eight years. When he stopped changing this solution, the heart cells died. The secret of the chick’s heart surviving for twenty-eight years lies in the fact that he kept the extra cellular fluids constant and also that he disposed of the cellular waste products every day by changing the fluid in which the chick’s heart was kept.
