It is, however, shown to be as great or even greater for all classes of crime in the Colorado climate, where wind is an important factor in the production of high electrical states. The other study, however, showed very slight wind effects for New York City, and their comparison with

this would seem to prove that the mental states of the suicide and of the street brawler are very differently influenced by it.

It is difficult, in conclusion, to summarize the results of this study in such a manner as to be of much value or to bring forward theories which are certain of any long tenure of life. The whole method of the study is too new and untried, and the number of data inadequate. The bare facts revealed in the preceding paragraphs must prove of much more value than any hypothesis drawn from them at this stage of the investigation. Still, there are a few generalizations which seem worth noting, especially as they are based in part upon findings which are entirely con-
