THE Victoria Institute, or Philosophical Society of Great Britain, has published, in pamphlet form, a paper by Professor Lionel S. Beale, in which that eminent physician and microscopist attacks, with free assertion and aspersion, the doctrine of the identity of living and not-living matter.
MANY of the most important discoveries of the psychologists were rejected by the physiologists, because they could not be proved by their law—and conversely with the psychologists. These contending forces have been brought into lasting alliance by Professor Calder-wood.
THE object of this paper is to briefly summarize the present knowledge of the liver-fluke, causing the much-dreaded and fatal “ rot ” in sheep. Professor A. P. Thomas, of Balliol College, Oxford, has completed his long and extended researches on this parasite, which have been carried on under the direction of the Royal Agricultural Society of England.
TOWARD the western portion of the United States, along the twenty-fifth parallel of longitude, lies a vast tract of sandy, arid country, known to the earlier geographers as “ The Great American Desert.” It is true, the limits of this great area have become circumscribed by the onward march of civilization, but the sandy waste is still there, and must ever remain.
IT follows from the exposition given in our former article that man, issuing from a “mother-region ” still undetermined, but which a number of considerations indicate to have been in the North, has radiated in several directions ; that his migrations have been constantly from north to south ; and that they have given rise to races the more ancient of which went farthest and were the most inferior.
IN the tragedy of errors, called the history of the human race, ignorance has often done as much mischief as sin ; and the erroneous theories of the cause—and, consequently, the proper cure — of the Poison - Vice have caused nearly as much misery as that vice itself.
THEORETICAL chemistry is based upon the molecular theory, according to which all matter is made up of molecules, and these molecules of atoms. The physical state of bodies depends upon the arrangement and motions of the molecules ; the other physical and chemical properties depend upon the kind and number of the atoms in the molecule, upon their arrangement and relative motions.
NURSING is as old as the human species. Even among animals, such as they are at present, we find occasional sympathy with fellow-suffering, and meet with efforts for the purpose of relief. We can not imagine that human beings, in ever so remote prehistoric times, should have lived together, or near each other, without mutual attempts at relief, when suffering or sick.
CLOTHING is a kind of armor to help us in the battle against the elements, the importance of which increases with the rigor of the climate which man inhabits. The house may be regarded as an amplified clothing, to be used less constantly, but as more enduring than other clothing, and capable besides of furnishing a full shelter.
IN the last quarter of a century, very important progress has been made in our home industries and foreign commerce ; but certainly the success that has been effected in the utilizing of waste products, and developing neglected ones, is not the least remarkable of recent scientific advances.
SINCE the publication of the interesting observations and speculations of Dr. Karl Brandt concerning the occurrence of chlorophyl in animals, of which a summary account was given in a recent number of this periodical, under the heading “A Partnership of Plant and Animal Life,” at least two important contributions to the same subject have made their appearance.
THE process of frying follows next in natural order to those of roasting and grilling. A little reflection will show that in frying the heat is not communicated to the food by radiation from a heated surface at some distance, but by direct contact with the heating medium, which is the hot fat commonly, but erroneously, described as “boiling fat.”
MY predecessor in office remarked, in the opening of his address, that two courses are open to the retiring president of this Association in preparing the annual presidential discourse—he may either take up some topic relating to his own specialty, or he may deal with various or general matters relating to science and its progress.
WHEN we contemplate the extraordinary diversity of colors offered to us by the numberless flowers and fruits, ranging through all possible gradations from the purest white to the most intense black, we can do no less than admire so surprising a wealth of color-shades, and are naturally prompted to imagine that chemical processes influence their tone and effect the manifold changes.
" A CHAMPION against the Cholera ” is the designation which Dr. Karl Stieler gives to the subject of this sketch, in his admirable biography of him in a former volume of “ Daheim,” to which we shall be largely indebted for such parts of our own article as are not mere date and detail.
DR. F. L. OSWALD’S answer in your last issue to my criticism demands a reply, for the purpose of elucidating who is in the right on questions closely appertaining to every one’s welfare. His personal allusions may be at once thrust aside as irrelevant.
WE are gratified in being able to report that the recent meeting of the American Association for the Advancement of Science, held this year at Minneapolis, was most satisfactory and successful. It was, of course, not so large as it would have been if convened in a more central and accessible place, but we have attended smaller gatherings of this body a good deal nearer the seaboard.
WE have from time to time made reference to this great work as its parts have successively appeared during the last fifteen years; but, having now assumed its completed or final form, we desire to call attention to it as a whole, and calculated to meet the wants of modern students in the way of a valuable work of reference.

The American Association,—The thirty-second annual meeting of the American Association for the Advancement of Science was opened at Minneapolis, Minnesota, August 15th, with the usual forms. The welcoming addresses were made by the Governor of the State, the mayor of the city, and Dr. Folwell, President of the State University, in whose halls the sessions were held.
H. C. LEWIS and G. F. Wright have made a detailed study of the southern boundary of the glaciated area of Ohio, which they find to be sharply defined, though not everywhere marked by such a relative excess of moraine accumulation as in Long Island, New Jersey, and Pennsylvania.
