IN the November MONTHLY we gave a brief account of Prof. Marey’s method of representing the step of animals by means of graphic illustrations, with its application to human locomotion; we will now consider it as applied to the more complex paces of the horse.
DESCARTES, Leibnitz, and all the great minds of the seventeenth century, believed that phenomena are such interdependent parts of one whole, that they require to be explained by each other, and consequently, that a very close mutual connection should be maintained among the sciences. In their view, this was the condition of rapid advance and intelligent development.
IN the former article, attention was given chiefly to what might be called structural and industrial considerations of our bivalve. We are now to note some matters in the life of the oyster of a natal character. Its friends and enemies must be looked after.
THE reign of Sirius is over, and the dread of hydrophobia has ceased to agitate the public mind. At this auspicious season of the year we may approach the subject with cool premeditation, and deal with it in our own way. No longer do we regard our canine associates with a sort of indefinable apprehension.
IN the advancing knowledge of physiology it has been discovered that all mental culture should be based upon the brain—that education should be pursued in harmony with the laws of life and health, and that, where these are violated, the advantages of the former afford poor compensation.
ALTHOUGH it is doubtless true that the superior dryness of seeds does enable them to resist the influence of heat longer than moist eggs are able to do, and therefore also enables them apparently to resist for a brief period a temperature notably higher than would h ave proved fatal to them had they been in a moist state—it is altogether another question when we have to decide whether moist Bacteria or their germs are endowed with this seed-like property of developing after desiccation.
WHEN the States-General of France were assembled for the last time at Versailles, after a long interval of inactivity, and an inaugural address was.pronounced by the Bishop of Nancy, Mirabeau passed upon his performance the sweeping criticism that he had missed the grandest opportunity ever offered to man for saying something or holding his tongue.
BEFORE concluding this portion of my address, I would draw your attention to the appliances used in the minor schools of this country for teaching geography, as they would seem to need some improvement. The appliances to which I allude are models or relief maps, wall maps, atlases, and globes.
ON the 8th day of the present month, at a little before nine in the evening of our time, the planet Venus will be first seen entering upon the face of the sun, from that side of the earth on which it is then day, and to observe the event astronomers will have made their way from all the principal countries of the civilized world.
WHOEVER has had an opportunity of becoming acquainted with the mental condition of the intelligent classes in Europe and America, must have perceived that there is a great and rapidly-increasing departure from the public religious faith, and that, while among the more frank this divergence is not concealed, there is a far more extensive and far more dangerous secession, private and unacknowledged.
WE give, this month, an excellent portrait of one of the most active and accomplished of our American scientists, one who has not only extended the boundaries of knowledge by his researches in the various fields of investigation to which he has devoted himself, but who has been a missionary of science to one of the old Oriental countries, and labored successfully to diffuse its benign influences among a semi-barbarous people.
IN the July number of THE POPULAR SCIENCE MONTHLY, there is an article entitled “The Hydraulics of Great Rivers,” said to have been mainly derived from an account, in the April number of the Edinburgh Review, of a book called “The Paraná, the Uruguay, and the La Plata Estuaries,” by M. Révy, a member of the Institute of Civil Engineers of Vienna.
A NEW standard has grown up in modern times by which the advance of nations may be measured. Hitherto, military power, extent of territory, historic prestige, and commercial resources, have been taken as the chief tests of national greatness.
THE fifth and concluding volume of Dr. Flint’s comprehensive work on physiology is now published, and we congratulate the author upon the completion of his task and the success of its execution. We gave a brief account of the general object of the work, in noticing a previous volume, and have only now to say that the concluding book of the series not only sustains, but surpasses, the high character won by its predecessors, while the whole work—the product of eleven years’ labor—is an honor to its author and a credit to the science of the country.
Does the Earth rotate at a Uniform Rate?—In the September number of Silliman's Journal, we find a remarkable paper by Prof. Newcomb, of the Naval Observatory, Washington, to the conclusions of which we wish to call the attention of our readers.
THE American Society of Civil Engineers have appointed a committee to report on plans for—1. The best means of rapid passenger transit; and, 2. The best and cheapest method of delivering, storing, and distributing goods and freight in and about the city of New York.
