vessels are comparatively slight, it is found that a shot going through the side exposed, makes a clean hole of its own size, which might be readily stopped; but on the opposite side of the vessel the effect is terrific, tearing off large sheets; and even when the shot goes through, the rough edges being on the outside, it is almost impossible to stop the hole. If the vessels are more substantially constructed the principal injury takes place on the side exposed; and this is so great that two or three shot, or even a single one, striking below water line, would endanger the ship. As the result of the whole series of experiments, the opinion is expressed that iron, whether used alone or in combination with wood, can not be beneficially used for the construction of vessels of war.----The wires of the submarine telegraph having been found too weak to withstand the force of the waves, it has been determined to incase the wires in a ten-inch cable, composed of what is called "whipped plait," with wire rope, all of it chemically prepared so as to protect it from rot, and bituminized. A wire thus prepared is calculated to last for twenty years.----In the allotment of space in the Industrial Exhibition, 85,000 square feet have been assigned to the United States; 60,000 to India; 47,050 to the remaining British colonies and possessions; 5000 to China.

William H. Goold, has been commenced. The doctrinal works will occupy five volumes, the practical treatises four, and the polemical seven. The first volume contains a life of Owen, by Rev. Andrew Thomson of Edinburgh. This edition is edited with remarkable fidelity and care, and will prove a valuable accession to theological literature.----Washington Irving has received from Mr. Murray £9767 for copyrights and £2500 from Mr. Bentley, who has paid nearly £16,000 to Cooper, Prescott, and Herman Melville.----The Principal Theological Faculties in Germany are those of Berlin and Halle.
