CANCER OF THE BREAST
Dr. Todd at Hampstead, again, has shown that the interactions of the blood between fowl and fowl can be so used as to enable the biologist to identify any given hen and its family from any other hen in the world.
Abstract
samples of crystallized egg albumen from the eggs of a duck and hen respectively, can tell, by means of a biological test, which of them comes from which bird with great rapidity and certainty, though the detection depends on a subtle difference of molecular pattern far beyond the reach of any analysis by the chemist. Dr. Todd at Hampstead, again, has shown that the interactions of the blood between fowl and fowl can be so used as to enable the biologist, if he desires it, to identify any given hen and its family from any other hen in the world. No organic chemist has ever dreamed of performing in such subtlety as that.
