The American Association, recently in session at Ann Arbor, Michigan, elected the following officers for next year's meeting: President, E. S. Morse, Salem, Massachusetts; Vice-Presidents, J. W. Gibbs, New Haven, Connecticut; C. F. Brackett, Princeton, New Jersey; H. W. Wiley, Washington, D. C.; 0. Chanute, Kansas City, Missouri; T. C. Chamberlin, Washington, D. C; H. P. Bowditch, Boston, Massachusetts; Horatio Hale, Clinton, Ontario; Joseph Cummings, Evanston, Illinois; Permanent Secretary, F. W. Putnam, Cambridge, Massachusetts (holding over); General Secretary, S. G. Williams, Ithaca, New York; Assistant Secretary, W. II. Pettee, Ann Arbor, Michigan; Treasurer, William Lilly, Mauch Chunk, Pennsylvania. Buffalo, New York, was selected as the place for holding the meeting in 1886.
M. Tacchini mentioned to the French Academy of Sciences, July 27th, that red sunsets, like those of 1883-'84, though less intense, had appeared again; and said that the present phenomena could not be connected with the eruption of Krakatoa. At the same session of the Academy, M. Janssen read a paper by M. Landerer on the reappearance of the glows. This author thought them of cosmical origin, and suggested that they might be caused by the passage of Biela's comet.
Professor Peter T. Austen has investigated the relation of aluminic and ferric salts to plant-life. He finds that these salts have the property of precipitating dissolved organic matters, and causing the coagulation of suspended inorganic matters. The substances thus deposited are of high value as plant-food, and are placed in the most available state and most assimilable condition. "Thus we see that when the soil is unable directly to bind the plant nutriment, the acid products of the death of the plant, and probably also of the bacterial fermentations, supply agents which precipitate these plant-foods in such a state that mere mechanical filtration will remove them, and leave them stored up for future use by the plants." These processes also serve animal life by purifying the water.
Dr. R. Harvey Reed, of Mansfield, Ohio, after a study of the subject as it affects his own State, concludes that among the results of the destruction of the forests and the drainage of the land are more wind, more humidity, more rainfall, more dust, more sudden dashes of rain; more sudden changes from one extreme to the other of temperature and moisture; more rapid transmission of water from the periphery to the great basins; robbery of the natural regulators of distribution; and diminution of the common supply of springs and wells. These changes have been followed by a decrease of all forms of malarial diseases, and an increase of typhoid fever, catarrh, deafness, and chronic pulmonary troubles, and the increase in wind and dust favors the spread of zymotic and contagious diseases.
A correspondent, noticing our reference in a recent sketch of M. Chevreul to the discrepancy in the age of the distinguished chemist's father at his death, as given in Larousse's "Cyclopædia" (ninety-one years), and by the "Lancet" (one hundred and ten years), calls attention to another equally curious mistake respecting M. Chevreul in Schaedler's "Technologie der Fette und Oele." In the historical introduction to this work occurs a passage which we translate thus: "Only thirty years after the discovery of glycerine, in the year 1813, began the researches of Chevreul (born 1786, at Anders, died 1840)." On page 1105, the author appends the correction: "The information was given me privately that Chevreul died in 1840; but I have received from M. J. Bang, of Marseilles, under date of May 11, 1883, the following literal statement: 'I can assure you that Chevreul is still very active, and continues his course at the Museum, and is present every Monday at the Academy of Sciences. He is now ninety-seven and a half years old, but is, they say, livelier than ever.'"
The authorities of Albany, Georgia, have efficiently drained a troublesome pond by boring a well-hole through the ground to a deep subterranean stream. An outlet for the sewerage of a large Western university has been found in one of the numerous "sink-holes" with which the cavernous limestone of the country is marked, where a similar underground stream carries the stuff to parts unknown. Such expedients are good, provided the subterranean stream selected for the sewer-outlet is not a source of supply for some well. 864
��THE POPULAR SCIENCE MONTHLY.
��The State Board of Health of Massa- chusetts continues to follow up the use of arsenic in manufactures under all its dis- guises. They still tind the poison in dan- gerous proportions in papers of various colors, particularly in the glazed papers of fancy boxes, cornucopias, confectionery- boxes, etc., concert tickets, and playing- cards, and iu children's toys and articles of clothing. " German fly-paper " is soaked in arsenite of sodium, and is dangerous in more ways than one. The "Buffalo Carpet Moth Annihilator" contains 6 - 7l26 per cent of crystals of white arsenic, and " Rough on Hats " contains white arsenic crystals.
Paper bedclothes are made at a factory in New Jersey. They are doubled sheets of manila paper, strengthened with twine, and valuable by reason of the peculiar proper- ties of paper as a non-conductor of heat. They have a warmth-preserving power far out of proportion to their thickness and weight.
The Swedish papers report that a crane was shot at Orkened, in Scania, on the 19th of June, which bore a card containing the verse
" I come from the burning sand, From Soodan, the murderers' land, Where they told the lie That Gordon would die."
The bird had previously been wounded in the wing, and was much exhausted.
The Aberdeen (Scotland) "Journal" records a remarkable instance of the effect of atmospheric influences on the visibility of lights at night. In March, 1885, the captain of the steamer City of Aberdeen saw the Girdleness light in Aberdeen Bay, at the distance of more than thirty-six miles, and the Buchan-Ness light when it was thir- ty-two miles off. The distances at which these lights are considered ordinarily visi- ble are nineteen and seventeen miles re- spectively.
The " Lancet " publishes a list of facts to show the dangerous character of foot-ball. In its casual examinations of the papers, it has, without making special search for them, recorded some dozen or more instances of serious accidents in which bones were bro- ken one of which resulted in death, that occurred in the course of games. While the "Lancet" thinks it would be unwise and undesirable to abolish the game, which is the principal winter amusement of thou- sands of young people, it calls for a reform in the rules and practice, with such regu- lations as will reduce the number and se- verity of accidents, which, being secured, it believes the sport is capable of far more good than harm.
M. J. C. IIouzEAtr, in examining some old astronomical manuscripts at Brussels,
��has met the works of three Belgian astron- omers whose names were previously un- known. Henry Selder observed at Tournai in the fourteenth century. In 1340 he had compared Ptolemy's catalogue of the stars with the sky, to ascertain what stars had disappeared and what changed magnitude since the catalogue was compiled. He also compiled a second series of observations in 1367. Eustache de Eldris, who styled him- self an astronomer of Liege, made tables of the planets ; and Henri of Malines wrote a treatise on astrology.
Mr. Pi. A. Mullan, an Irish solicitor, mentions the singular observation during a hailstorm in County Down, that some of the hailstones perhaps one in a hundred were of a decided red color. Taking up some of them, he found that the color was not mere- ly superficial, but pervaded the substance of the hailstones, and, on melting, they stained his fingers.
��OBITUARY NOTES. Ms. N. W. Posthumus, Director of the Higher Burgher School, at Amsterdam, who died recently, was one of the founders of the Dutch Geographical Society, its secre- tary from the beginning, and one of the editors of its journal. He was forty-seven years old.
Dr. Barius, surgeon - general to the French army in Tonquin, died in Haiphong June 10th. He was known to the scien- tific world by his meteorological writings, of which the principal essay embodied his researches on the climate of the Senegal. He kept a regular series of observations at Haiphong.
Dr. Emil Riebeck, a distinguished trav- eler, recently died suddenly at Feldkirch, Germany, where he was preparing for a five years' journey. Besides being a traveler himself, he was a liberal patron of explor- ers. He had borne the expense, among other enterprises, of Dr. Schweinfurth's re- cent researches in Socotra.
Mr. W. S. W. Vaux, F. R. S., a numis- matist and Oriental scholar, and Secretary of the Royal Asiatic Society, is dead, at the age of sixty-seven years.
M. Henri Tresca, an eminent French physicist and engineer, died in June, in the seventieth year of his age. He filled the chair of Industrial Mechanics in the Con- servatoire des Arts et Metiers, and was the author of works on "Applied Mechanics" and the "Flowing of Liquids." He was elected a member of the French Academv in 1872.
Professor A. W. Eklund, a distin- guished Swedish physicist, has recently died at Lund, aged ninety years.
