In my presidential address, which I had the pleasure of reading before this society at our first meeting this year, I called attention, somewhat hurriedly, to the results of a few of my experiments on induction, and at the same time expressed a hope that at a future date I might be able to bring them more prominently before you. That date has now arrived, and my endeavor this evening will be to... more...

The death of this distinguished man must be recorded. An interesting résumé of his labors by M. Daubree has appeared, from which we take the following facts. After a training in his native town at the Lyceum of Metz, which furnished so many scholars to the Polytechnic school, Delesse was admitted at the age of twenty to this school. In 1839 he left to enter the Corps des Mines. From the beginning of... more...

One afternoon, in the autumn of 1872, I was riding leisurely down the sandy road that winds along the top of the water-shed between two of the smaller rivers of eastern Virginia. The road I was travelling, following “the ridge” for miles, had just struck me as most significant of the character of the race whose only avenue of communication with the outside world it had formerly been.

It is, perhaps, more difficult to write accurate history than anything else, and this is true not only of nations, kings, politicians, or wars, but of events and things witnessed or called into existence in every-day life. In The Engineer for September 17, 1880, we did our best to place a true statement of the facts concerning the Rocket before our readers. In... more...

BRISTOL CATHEDRAL. BRISTOL CATHEDRAL.

When Edmund Knowle was abbot, from 1306 to 1332, the Norman choir was replaced by that which now exists. His successor, Abbot Snow, built the chapels on the south side of the choir. Abbot Newland,... more...

The Colonel was the idol of his bragging old regiment and of the bragging brigade which for the last six months he had commanded. He was the idol, not because he was good and gracious, not because he spared his soldiers or treated them as fellow-citizens, but because he had led them to victory and made them famous. If a man will win battles and give his brigade a right to brag loudly of its doings, he... more...

DRYDEN ON SHAKSPERE. "Dryden may be properly considered as the father of English criticism, as the writer who first taught us to determine upon principles the merit of composition."—Samuel Johnson. No one of the early prose testimonies to the genius of Shakspere has been more admired than that which bears the signature of John Dryden. I must transcribe it, accessible as it is elsewhere, for... more...

THE USE OF IRON IN FORTIFICATION. Roumania is thinking of protecting a portion of the artillery of the forts surrounding her capital by metallic cupolas. But, before deciding upon the mode of constructing these formidable and costly affairs, and before ordering them, she has desired to ascertain their efficacy and the respective merits of the chilled iron armor which was recently in fashion and of... more...
