in the torrid zone, where the heat produces a general depletion of energy for motor discharge, than in the temperate regions, where the climate is exhilarating. The study, from the social standpoint, too, leads us to the same conclusion. The excess of crime in the social whirlpools of our great cities is convincing, and especially the careful study made by Morselli of the prevalence of suicide in the different countries of Europe, interpreted in the light of what we know of their social conditions.

Yet, in considering the facts disclosed by the present paper, we must not dogmatically assert that each is of the importance that the figures indicate. In fact, it seems evident from a careful study of the sheets, which show all the conditions together for the same day—a thing impossible with the charts illustrating this paper—that the various conditions for the day mutually react and interact upon one another, certain combinations seemingly resulting in a re-enforcement of the tendency to crime, while certain others inhibit it. Space forbids any full discussion of this phase of the problem in the present paper, but it very probably will be made the subject of some future study.

Author's Note.—The above paper was written more than a year ago. Since that time the work of comparing the prevalence of crime with the meteorological conditions has been carried on upon a much larger scale in the city of New York. An immensely greater number of data have served to corroborate the earlier conclusions arrived at in this Denver study, only in minor points—and those directly traceable to the very different climates—proving at all in opposition to them.—New York, July 1899.

 

THE SURVIVAL OF AFRICAN MUSIC IN AMERICA.

By JEANNETTE ROBINSON MURPHY.

FIFTY years from now, when every vestige of slavery has disappeared, and even its existence has become a fading memory, America, and probably Europe, will suddenly awake to the sad fact that we have irrevocably lost a veritable mine of wealth through our failure to appreciate and study from a musician's standpoint the beautiful African music, whose rich stores will then have gone forever from our grasp.

During my childhood my observations were centered upon a few very old negroes who came directly from Africa, and upon many others whose parents were African born, and I early came to the conclusion, based upon negro authority, that the greater part of their music, their methods, their scale, their type of thought, their dancing, their patting of feet, their clapping of hands, their
