SINCE the earliest recorded observations of insect-life, the ant has been a subject of especial comment and wonderment. Found throughout the range of both temperate and the torrid zones, it is in the tropics that the most interesting species abound, and where their vast numbers and their industry and fearless pertinacity make them a veritable scourge.
I PROPOSE in this lecture to consider speculations of quite recent days about the beginning and the end of the world. The world is a very interesting thing, and 1 suppose that from the earliest times that men began to form any coherent idea of it at all, they began to guess in some way or other how it was that it all began, and how it was all going to end.
BY sexual cerebration is meant the existence of sex in the emotional and ideo-motor psychical nature of women and men, from which originate per se emotioixs and states of consciousness which distinguish and give character to the intellection of the sexes.
I HAVE suggested the thought of a God revealed in Nature, not by any means because such a view of God seems to me satisfactory, or worthy to replace the Christian view, or even as a commencement from which we must rise by logical necessity to the Christian view.
THE bird which is the subject of this sketch is familiar to all who walk in green pastures and beside still waters ; for in such haunts do the Bank-Swallows congregate in merry companies, making up for their want of companionship with man, which is so characteristic of the other hirundines, by a large sociability among themselves.
THE regions called circumpolar, during the last six or seven years, have been the theatre of numerous explorations that have enriched our geographical maps with many new outlines. Doubtless, the recent discoveries have not succeeded in penetrating the mystery that envelops the arctic world, but, by strength of will, and thanks also to the connivance of chance—sometimes propitious to navigators—important points of departure have been obtained from extreme latitudes.
THE obvious necessity of association as a primary condition of development leaves little to be said on that subject. To the manifestation of this soul of progress a body social is requisite, as, without an individual body, there can be no manifestation of an individual soul.
THE thunder-shower of Southeastern Vermont generally comes from the southwest. To understand why it should take this course instead of any other, we must examine the topographical chaiacter of the country. The chain of Green Mountains extends throughout the State from south to north, inclining some degrees to the east of north.
DURING the present century, a great number of exotic plants and trees have been brought to Europe, or transplanted from their original habitat to other climes. In view of its usefulness, perhaps the blue-gum tree of Australia and Tasmania, belonging to the genus Eucalyptus, which includes upward of 150 species, holds the first place among these exotic plants.
THAT the Sun causes a saving of fire and candle was known to all antiquity from the day fire and candle were first invented ; and that was nearly all they knew about him. Nothing more was known for ages. It was only yesterday that he set up the business of sketching portraits and no matter what.
RICHARD A. PROCTOR THERE are questions admitting, when viewed in the abstract, of but one answer, which yet, considered in their practical aspect, present difficulties that are almost, if not wholly, insuperable. Among them must be reckoned one which before long will attract, as it preeminently deserves, the attention of the nation—the question whether it is desirable that the investigation of natural facts, regarded as a vocation, should be publicly endowed.
THE subject of this sketch is a typical example of that remarkable class of men who achieve great eminence, both in business and in science ; he is a very distinguished scientific investigator, having not only made his name a household word in all chemical laboratories where galvanic batteries are used, but he was one of the early pioneers in establishing the grand doctrine of the correlation of forces, and is known and esteemed throughout the scientific world for his share in this great movement.
DEAR SIR : Last summer, at the Hartford meeting of the American Association for the Advancement of Science, a new constitution was adopted, and, under its provisions, a permanent subsection of “ chemistry, chemical physics, chemical technology, mineralogy, and metallurgy,” was organized.
THE so-called “Association for the Promotion of Social Science” held its last meeting in May, in Detroit. It is reported as a satisfactory session, there having heen a good attendance, much interest, and a full invoice of papers upon the varied topics which it is the habit of the body to consider.
THE LIFE AND GROWTH OF LANGUAGE : An Outline of Linguistic Science. By WILLIAM DWIGHT WHITNEY. Pp. 326. New York: Appletons (International Scientific Series, Yolume XVI.). Price, $1.50. EVER since the fifteenth century the study of languages, particularly of Latin, Greek, and Hebrew, has formed the basis of a “ liberal education ;” and yet it was not till our own day that such a thing as a science of language was thought possible.
Notices of Recent Earthquakes.—The American Journal of Science for May gives a summary of earthquakes for the year 1874, prepared by Prof. C. G. Rockwood, Jr., of Rutgers College, New Jersey. They are reported from nearly all quarters of the globe, forty-three in number.
Correction.—Prof. Henry Wurtz corrects an error in the theory of A. McDougall, of the Manchester Literary and Philosophical Society, on the possible mode of formation of graphite, as given in our Notes for last month. As he points out, the carbon which collects in gas-retorts does not give the reactions of graphite with a mixture of chlorate of potassium and nitric acid ; it is not converted into graphitic acid ; therefore it is not graphite at all, and of course its formation cannot explain the formation of that mineral.
