THE STUDY OF MANKIND. Professor Max Muller, who presided over the Anthropological Section of the British Association, said that if one tried to recall what anthropology was in 1847, and then considered what it was now, its progress seemed most marvelous. These last fifty years had been an age of discovery in Africa, Central Asia, America, Polynesia, and Australia, such as could hardly be matched in any... more...

THE COMPOUND STEAM TURBINE. Last year the whole of the lighting of the Newcastle Exhibition was effected by the agency of seventeen of these motors, of which four were spare, giving in the aggregate 280 electrical horse power. As the steam was provided by the authorities of the exhibition, it was good proof to the public that they had satisfied themselves that the consumption would not be extravagant... more...

DATES AND THE DATE PALM. Even those whose knowledge of the customs of the Orient extends no further than a recollection of the contents of that time-honored story book, the "Arabian Nights," are doubtless aware that, since time immemorial, the date has been the chief food staple of the desert-dwellers of the East. The "handful of dates and gourd of water" form the typical meal and daily... more...

THE LIFE AND CHARACTER OF OUR RELIGION. The character which the gospel of Christ requires is made up of all that is lovely, is formed upon the highest model, but it is not composed of the insensibility, the anger, the pride, the egotism, the worldliness, which is so common among men. It is not the cold indifference of modern moralists; it is not the rank and scepticism of modern doubters, nor yet the... more...

A VISIT TO THE CREUSOT WORKS. Here we are at the great forge (Fig. 1), that wonderful creation which has not its like in France, that gigantic construction which iron has wholly paid for, and which covers a space of twenty-four acres. We first remark two puddling halls, each of which contains 50 furnaces and 9 steam hammers. It is in these furnaces that the iron is puddled. The ball or bloom thus... more...

I have the honor this evening of addressing a few remarks to you upon the subject of influence machines, and the manner in which I propose to treat the subject is to state as shortly as possible, first, the historical portion, and afterward to point out the prominent characteristics of the later and the more commonly known machines. The diagrams upon the screen will assist the eye to the general form... more...

THE RAPHAEL CELEBRATION AT ROME. The most famous of Italian painters, Raffaele Sanzio, whom the world commonly calls Raphael, was born at Urbino, in Umbria, part of the Papal States, four hundred years ago. The anniversary was celebrated, on March 28, 1883, both in that town and in Rome, where he lived and worked, and where he died in 1520, with processions, orations, poetical recitations, performances... more...

GUSTAVE TROUVÉ. The accompanying portrait of M. Gustave Trouvé is taken from a small volume devoted to an account of his labors recently published by M. Georges Dary. M. Trouvé, who may be said to have had no ancestors from an electric point of view, was born in 1839 in the little village of Haye-Descartes. He was sent by his parents to the College of Chinon, whence he entered the École des Arts et... more...
