✦ Synopsis
These ten experiments seem to show definitely how and why wall figures of the two1 types treated are produced.
The facts proved are in accordance with what one would expect on the basis of ordinary physical common sense. On account, however, of the methods us'ed in this work it is not claimed that other factors than those affecting the distribution of moisture films as influenced b'y temperature may not contribute in a minor way to the formation of figures of the first kind. It is merely contended that under all ordinary conditions the temperature-moisture distribution is the factor of predominating importance being necessary and sufficient to produce all of the observed effects.
