THE RELATIONS BETWEEN THE MIND AND THE NERVOUS SYSTEM.
WILLIAM A. HAMMOND
IN order that one person may know what another person is talking about, there must be an agreement in regard to the meaning of the terms employed. Without this there can be no common ground on which those engaged in a discussion as speakers and listeners can stand.
THE German practical-schools (Realschulen) are a recent institution as compared with the classical-schools (Gymnasien), and have never yet obtained more than a scanty allowance from the public treasury, from which their ancient rivals have long received an abundant support.
SIR: As you have placed before a multitude of readers Mr. Frederic Harrison's anniversary address on "The Memory of Auguste Comte and his True Works," I may, I think, properly ask you to place before the same readers the disproof of a statement made by Mr. Harrison which gravely compromises me.
THE term “mud-sill” is supposed to be used contemptuously in the Southern States to designate the lowest rank of the people : those who use nothing and have nothing to use but muscle for their maintenance ; men who are uneducated and indifferent to education ; men without other aspiration or ambition than that which incites them to appease their hunger and to ward off the blasts of winter.
MR. PRESIDENT, FELLOWS AND MEMBERS OF THE ASSOCIATION, LADIEs AND GENTLEMEN: Thirty-six years ago this very month, in this city, and near the place where we are now assem bled, the American Association for the Advancement of Science was organized, and held its first meeting.
THE extraordinarily disastrous floods of 1883—’84, in the Ohio River, have again called public attention to the close relation which the wooded or unwooded condition of steep hill-sides, in the areas drained by streams, bears to the volume of water flowing in them.
THE conjunction of the meeting of the American Association with the opening of the Electrical Exposition and the sittings of the National Electrical Congress leads me to say a few words upon a question which we all ask ourselves, and to which we have hitherto had no response : “ What is electricity ? ”
THE products of the extinct and the still active volcanoes of Chili, of which Pissis enumerates not less than seventy, are of contemporary origin with the diluvial and alluvial strata of the country. Of the gaseous emissions of their craters, it need only be mentioned that, as in all American volcanoes, chlorine is weakly represented.
IN my last I referred to Rumford’s anticipation of the results of modern chemical analysis in his selection of the materials for his economical feeding of the poor of Munich ; but, as may be supposed, all his theoretical speculations have not been confirmed.
THE peoples with whom missionaries have occasion to become acquainted in Damaraland belong to different races; and the materials for a fair ethnological museum might easily be collected at any of the more important places. The agricultural Ovambos and the nomadic Hereros and Ovambandierus belong to the Bantu race, the Namaquas and Bushmen to the yellow Hottentot stock, while the tribe called the mountain Damaras are a black people of doubtful origin.
GRIMM tells, in his “Legal Antiquities of Germany,” of a peculiar custom which existed, in the duchy of Carinthia, during the election of a new duke, till a comparatively recent period. So long as affairs continued unsettled, relates the narrative from which he quotes, the Gradnecks had the right, which had come down to them from of old, to mow as much hay as they could, robbers to plunder, and pirates to ravage the land at will with impunity, unless peace was made with them.
IT may be, that if the sages of prehistoric China, or the Magi of Chaldea and other ancient civilizations, could return to enlighten our ignorance, they might prove to have possessed far more scientific knowledge than we give them credit for, with some points of practical application which we marvel to think could ever have been forgotten.
THE name of Professor James Hall is inseparably associated with the growth of American geology, the classification of the palæozoic strata of the continent, and the systematization of their paleontology. Connected with the New York State Geological Survey since 1837, he has been for about forty years, as chief of the paleontological department, engaged in the study of fossil remains.
THE recent meeting of the American Scientific Association at Philadelphia was an eminently successful one.It was the largest ever held, the number of papers read was greater, and their merit above the past average. The presidential address by Professor Young, which we reprint, was a production of unusual ability.
A NATURALIST’S RAMBLES ABOUT HOME. By CHARLES C. ABBOTT. New York: D. Appleton & Co. Pp.485. Price, $1.50. THERE is no denying that natural history is one of the most fascinating of subjects, and now and then there appears a book written by some enthusiastic lover of nature, who has entered into communion with the inferior animate creatures, and writes a living book so pleasing and attractive that it is sought by readers with the avidity of a romance.
British Association Addresses.—Professor Roscoe’s address before the Chemical Section was on “ The Progress of Chemistry since 1848.” The author made the year 1848 a dividing line between the epoch of Berzelius, which closed then, and that of Dumas and Wurz, which closed in 1884.
AN “American Electrical Exhibition” will be opened in the Massachusetts Charitable Association Building,Huntington Avenue, Boston, November 24th, and will be continued till January 3, 1885. It is intended to make the exhibition complete and comprehensive in every particular, and to exceed in novelty any that has ever been held in New England.
