FARCOT'S IMPROVED WOOLF COMPOUND ENGINE. In a preceding article, we have described a ventilator which is in use at the Decazeville coal mines, and which is capable of furnishing, per second, 20 cubic meters of air whose pressure must be able to vary between 30 and 80 millimeters. In order to actuate such an apparatus, it was necessary to have a motor that was possessed of great elasticity, and... more...

THE FRENCH SCIENTIFIC STATION AT CAPE HORN. In 1875 Lieutenant Weyprecht of the Austrian navy called the attention of scientific men to the desirability of having an organized and continual system of hourly meteorological and magnetic observations around the poles. In 1879 the first conference of what was termed the International Polar Congress was held at Hamburg. Delegates from eight nations were... more...

The inauguration of the statue of Philip Lebon, the inventor of lighting by gas, occurred on the 26th of June, at Chaumont, under the auspices of the Technical Gas Society of France. The statue, which we illustrate herewith, is due to the practiced chisel of the young sculptor Antide Pechine, who has perfectly understood his work, and has represented the inventor at the moment at which he observes a... more...

ST. DUNSTAN'S, FLEET STREET. No church in London is perhaps better known than the above, which is distinctively called Saint Dunstan's in the West. External elegance has little to do with this celebrity, which has been acquired by the two wooden figures placed on a pediment in front, representing savages, who indicate the hours and quarters by striking a bell with their clubs: this has caused... more...

E. FELICE FORESTI. Late in the autumn of 1836, an Austrian brig-of-war cast anchor in the harbor of New York; and seldom have voyagers disembarked with such exhilarating emotions as thrilled the hearts of some of the passengers who then and there exchanged ship for shore. Yet their delight was not the joy of reunion with home and friends, nor the cheerful expectancy of the adventurous upon reaching a... more...

THE STORY OF JOSIAH HENSON No one ever uttered a more forceful truth than Frederika Bremer when she said in speaking to Americans: "The fate of the Negro is the romance of your history." The sketches of heroes showing the life of those once exploited by Christian men must ever be interesting to those who would know the origin and the development of a civilization distinctly American. In no case... more...

O the angels know the blessed day, And strike their harps anew? Then may the echo of their lay Float sweetly down to you, And fill your soul with Christmas song That your heart shall echo your whole life long. Havergal. A bright and happy Christmas to you! Lift up yourselves to the great meaning of the day, and dare to think of your humanity as something so sublimely precious that it is worthy of being... more...

ELECTRICAL LABORATORY FOR BEGINNERS. By GEO. M. HOPKINS. It is only when theory and practice, study and experiment, go hand in hand that any true progress is made in the sciences. A head full of theory is of little value without practice, and although the student may apply himself with all his energies for years, his time will, to a great extent, have been spent in vain, unless he by experiment rivets... more...

SIR WILLIAM FOLLETT. The disappearance from the legal hemisphere of so bright a star as the late Sir William Follett, cast a gloom, not yet dissipated, over the legal profession, and all classes of society capable of appreciating great intellectual eminence. He died in his forty-seventh year; filling the great office of her Majesty's Attorney-general; the head and pride of the British Bar; a... more...

M. LOUIS BLANC M. Louis Blanc, a democratic journalist, with all, and perhaps more than the usual talents of the Parisian journalist—with all, and more than the usual faults of one—has undertaken to write the history of his country, during and since the revolution of 1830. What can we expect to be the result of such an undertaking? What can we expect from a man who sits down to a task of this... more...
