Agreat deal of misapprehension has arisen from consideringthat the front of these hot and cold waves is nearly vertical,while records on Mount Washington, Pikes Peak, and othermountains have shown that these conditions are far ahead inthe upper air. At Mount Washington they are 24 hoursahead, although a part of this is due to a slightly greater inso-lation after the hot wave has begun at the earth and a greaterheat radiation after the cold wave has begun. A very careful study of records near the earth has estab-lished the law of diminution up to 1,000 ft., and now thataccurate balloon observations are being greatly multiplied, wemay hope to learn a great deal in regard to temperature con-ditions up to heights of 12 or 15 miles. The enterprise ofDr. A. Berson, in taking up a cylinder of oxygen and, by.
