Rh made illegal. Let the two exist together, and experience will prove which is the one preferred by the community.

P. S.—Very probably the old stalking-horses will be trotted out on Wednesday, and the President of the Board of Trade will be told of the confusion created by the existence of mere local weights and measures. I believe that if those who cite these anomalies were asked to give instances at various dates it would be found that these local weights and measures were dying out. In any event they are illegal, and are not obligatory upon anybody. Every man can claim to deal according to the standards of length, of weights, and of capacity. Most certainly the introduction of the metric system would largely add to the use of illegal weights and measures, not only locally, but generally. If the inquiry were made in France, even no farther off than Boulogne, it would be found that, in the markets there, dealings are frequently carried out on a local system unconnected with the metric.—F.

Variations in African Religious Ideas.—Miss Kingsley observes, in her West African Studies, that when you are traveling from district to district you can not fail to be struck by the difference in character of the native religions you are studying, and that no wandering student of the subject in western Africa can avoid recognizing the existence of at least four distinct forms of development of the fetich idea. They have every one of them the same underlying idea, and yet they differ. "And I believe," Miss Kingsley says, "much of the confusion which is supposed to exist in African religious ideas is a confusion only existing in the minds of cabinet ethnologists from a want of recognition of the fact of the existence of these schools. For example, suppose you take a few facts from Ellis and a few from Bastian and mix, and call the mixture West African religion. You do much the same sort of thing as if you took bits from Mr. Spurgeon's works and from those of some eminent Jesuit and of a sound Greek churchman and mixed them, and labeled it European religion. The bits would be all right by themselves, but the mixture would be a quaint affair." Of the four main schools of fetich predicated by Miss Kingsley, the Tshi and Ewe school (Ellis's school) is mainly concerned with the preservation of life; the Calabar school with attempting to enable the soul successfully to pass through death; the Mpongwe school with the attainment of material prosperity; and the school of Nkissi with the worship of the mystery of the power of evil.

A Natural History Society as a School.—Among the agencies employed by the Boston Society of Natural History for making itself a vehicle of instruction to the public has been the employment of an educated man and teacher as guide to the museum, who should also give lectures there. The salary of this officer has heretofore been provided by the bounty of Miss Harriet E. Freeman, but she has been obliged to discontinue her contribution, and the curator is now seeking other means of maintaining a suitably qualified assistant. The "guide," Mr. A. W. Grabau, delivered a course of lectures in April and May, 1897, on "The Surface of the Earth: Its Rocks, Soil, and Scenery," in which special attention was given to the scenery in New England; and, whenever it was practicable, excursions were made to localities which could be used as illustrations. A similar course, delivered in 1897, resulted in the formation during the summer of the same year of a class of thirty persons, summer residents of Kennebunkport, Maine, who were under Mr. Grabau's daily instruction for two weeks. The awakening of interest in local scenery further led to his giving lectures in Belmont and Arlington, and he thereby became instrumental in a movement intended to preserve the local frontal bowlder moraine on Arlington Heights—a valuable geological movement. A course of lectures on the Animals of the Shores of New England was given by Mr. Grabau to a class of from forty to seventy-five persons, in the Teachers' School of Science, with excursions on Wednesday and Saturday afternoons. In a similar fall course attention was given specially to the study of animals in their various habitats.
