The result of meteorological tests with balloons at immense heights is nnnounced from Bremen. One balloon, carrying self-registering instruments, reached a height of twelve miles. The thermometer could not register the temperature, 67 degrees beli zero being marked at a lower height. Many tests show that the temperati sinks gradually up to two and a half miles. Above that the fall is much more rapid.
