The adoe of some former (deceased) magistrate is then called upon to turn away the evil; and when any-one is cursed, he endeavors to ward off the effect of the imprecation by an offering. Adoes are also made and offered to drive off evil spirits or to warn off the spirits of pestilence that may be approaching the village. The occasions for offering are, in fact, innumerable, and persons who suffer much from illness are made poor on account of them.

The field of superstition is much better tilled by the Niha people than are their rice-fields.—Translated for the Popular Science Monthly from the Allgemeine Missions-Zeitschrift.



THE close connection between animals and their surroundings is generally recognized both by those believing in creation by design and by those holding to evolution. This connection is usually supposed to be restricted to the adaptation of certain organs to specific facts of surrounding environment. Often-quoted examples of such related organs and conditions are the eye and light, and the ear and sound.

In addition to this undoubted adjustment of single organs to individual conditions of environment, there is reason for believing that each natural division of the great animal types, the most fundamental as well as the most trivial, is adapted in the same sense to its own special fact of environment. In other words, all modifications of type have been in the line of adaptation to special conditions; and, where such modifications are
