Transplanting the Organs of Dead Men Into Living Men.--To take from a recently dead individual a kidney, or a bone, or an artery, and by immersing them in certain fluids thereby keeping them alive indefinitely, and later transplanting them in the body of a living individual so that they will continue to live and perform their function in the new environment, is a revolutionary and a seemingly incredible performance. Yet Dr. Alexis Carrel of the Rockefeller Institute, New York, has accomplished this wonderful task. The smallest imagination can picture the possibilities of this kind of surgery, but, inasmuch as the discovery is so recent and the opportunities for testing it upon human beings are so relatively few, that time alone can tell how far it may be possible to go. Anti-Meningitis Serum.--Another important discovery that has emanated from the Rockefeller Institute is the Anti-Meningitis serum. The death rate from spinal meningitis, before the introduction of the serum, was 70 per cent., the use of the serum has reduced this percentage to 30. We owe this important contribution to Dr. Simon Flexner. A Serum for Malaria Now Possible.--Dr. C. C. Bass, of Tulane University, has succeeded in extracting malaria-producing parasites from human blood and keeping them alive in test tubes. This feat had been long attempted but never before with success. The significance of this achievement is that it is the first step toward preparing a serum that will give immunity to malaria.
