Injection of synthetic, cocaine-like drugs, such as novocain and procaine, into the canal of the spinal cord is objectionable because such injections act on the cord and brain, interfere with the heart. Anesthetics such as ether and nitrous oxide (laughing gas) are harmful because they cause a deficiency of oxygen in the blood streams of mother and child...
...experiments followed the same basic pattern: one group of rabbits was immunized with Type I antipneumococcus serum,* then half the group was stupefied with large doses of ethyl alcohol (or ether) that kept them under from three to 30 hours. Then the entire group received injections of Type I pneumococci. A second group of control animals was not immunized, but half that group was intoxicated and all were injected with the virulent germs, either in the flank or the lung...

...encouraged by private enterprise is the Federal Theatre Radio Division. For none of its 44 series has the F.T.R.D. ever paid the radio broadcasting systems any time charges.

Free time contributed to the project in two years is valued at more than $3,000,000, almost ten times the project's actual cost. And the project has succeeded in returning about half its actors to professional stage, screen or radio jobs...
...physical commotion caused by this report rose a burning question: Was it another proof of Relativity, or did it revive the ether concept, which has no place in a relativistic world? The answer to that question depends on whether the observed effects were due to absolute motion through an ether, or to relativistic motion, the motion of the particles relative to Dr. Ives' apparatus-a point which was not settled last week. In Princeton, Dr. Einstein accepted the experiment as another prop for Relativity. Some of his admirers agreed with him, but some of his critics thought the experiment...
