Calling for greater precautions and emergency preparations to safeguard fighting men from the hardships of war, Ross A. McFarlane, assistant professor of Industrial Research at the Business School, yesterday released further details on his recent 33,000-mile survey flight to Africa.

As a result of conferences with eight groups of submarine victims, for example, he is recommending that "greater care must be observed on merchant ships for the supply of adequate first-aid kits and emergency rations of food and water."

Studies High Flying

More particular attention, however, was devoted by McFarlane to the conditions under which current high-altitude flying must be carried on. "It is necessary for the planes to climb to heights at which their equipment is not really intended to fly if they hope to intercept successfully the German planes, which have small supercharged cabins in the cockpits," he said.

Although disappointed in finding that all the air ambulances which he had planned to observe had been shot down by the Nazis, McFarlane reports that he was particularly impressed with the effectiveness of the RAF medical work in the western desert.

New Drugs Available

New units and new drugs have made it possible to return to the front 600 of the 1000 men treated in one of these bases during one month, he said, adding that the cause of many injuries was the heavy traffic necessary on the supply lines during dust storms. "These storms are a more serious problem than the heat of the desert," he said.

McFarlane also inspected a group of doctors from the Harvard Medical School who, he says, "have been doing remarkable work" on the control of malaria in the Gold Coast Colony. By such measures as moving native villages they have reduced the incidence of malaria to less than one percent.
