Help from Dogs. Columnist Deutsch also repeated a conversation with Dr. Prinzmetal at a medical meeting in Chicago last summer, when Hearst's doctor was demonstrating an earlier heart technique involving radioactive sodium (TIME, July 5). Dr. Prinzmetal said he had tested his radiocardiograph on "scores" of dogs before it was used on humans and "our development of the radiocardiograph would have been impossible without dog experimentation." Asked Deutsch: "Then you don't advocate anti-vivisection?" Replied Dr. Prinzmetal: "On the contrary . . . medical research would be crippled without judicious use of animal experimentation...
There are plenty of propellants that burn when brought in contact with water, e.g., metallic potassium, sodium, white phosphorus, various metallic hydrides. Some of these can be used in convenient liquid form. When such fuels hit water, they decompose it violently by uniting with its oxygen, giving off heat and a large volume of hydrogen gas. The combustion chamber is shaped so as to make the expanding water-and-gas mixture shoot out the rear opening as a high-speed jet. The reaction from this drives the engine (and the torpedo) forward...
...with high blood pressure, or some diseases of the heart and kidneys, are often forbidden to use salt. Last spring the Foster-Milburn Co. of Buffalo thought it had found something harmless that would give food a salty flavor.

In a twilight state between wakefulness and deep sleep, the patient often says things he cannot or will not say when fully conscious. Narcosynthesis works best when the patient's difficulties are recent (as in some "war neuroses"). The most desperate treatment of all, for the patient who fails to respond to anything else, is a drastic brain operation, like lobotomy (TIME, Dec. 23, 1946). Lobotomy may relieve the more troublesome symptoms, but it may also leave the patient so irresponsible or lumpish...
