At a recent meeting of the Royal Society of Literature, Colonel Rawlinson read a most interesting paper, containing the announcement of a discovery of great historical importance. In looking over the large collection of new cuneiform inscriptions recently brought by Mr. Layard from Assyria, he has met with one recording the annals of the "Koyunjik King." Under the head of the third year occurs a notice which determinately proves the king in question to be the biblical Senacherib, and contains some other remarkable verifications of Scripture. The record, after giving an account of the king's war against the king of Sidon, and describing the battle between the Assyrians and Egyptians, in conformity with the statements of Josephus and Herodotus, presents a distinct notice of the proceedings of Senacherib against Hezekiah, king of Judea. The names in the inscription are Khazakiyah, Ursalimma, Jehuda; and the tribute which the Jewish king pays, in order to free himself from his enemy, is stated almost in the very words of Scripture. The annals of Senacherib in this inscription extend over seven years, and a cylinder has been met with which gives the events of two years more. Other points of identity between these annals and the Greek and the biblical notices of Senacherib likewise occur; but the chief point of interest is the establishment of the identity of the king who built the great palace of Koyunjik with that sovereign. A secure starting-place is now obtained for historical research, and it rapid progress will be made in fixing the Assyrian chronology. Colonel Rawlinson's paper was read at one of the four evening meetings which the Society has held this season for the reception of its foreign members and friends. The Earl of Carlisle was in the chair.
Attempts to discover a Perpetual Motion are still made in almost every country. In the United States a successful result is attained, according to the newspapers, about twice a year, and in Europe the inventive genius of the people is nearly as well rewarded. We read in the French paper appearing in Constantinople, that a Polish refugee of the name of Rudinski has discovered a sort of perpetuum mobile, at least an engine which somewhat approaches perpetual motion, for when once put in motion it can preserve it for twenty years. The power of this engine is said to be greater than that of any other yet known. The article in the same paper says that the inventor has made as a model a small carriage, 22 inches long, 11 inches wide and 14 inches high; that it carries a burden of one ton; and that its speed is a mile in a minute. The inventor is now occupied in building a mill after his method for the Turkish Government. The last American effort in this line is a "Static Pressure Rotary Engine," advertised by a Mr. Sawyer, and vindicated by Mr. Andrews, in a series of letters in the Tribune. Professor Loomis, of the New-York University, has taken the trouble to show that there is no discovery in the case. Mr. Sawyer's machine consist a of a covered cylindrical basin, 26 inches in diameter and two inches deep, to which is attached a vertical tube four inches in diameter and of any required length. A spiral groove runs the whole length of the tube, and this, together with the basin, is supposed to be filled with quicksilver. The whole is to be rapidly revolved about a vertical axis, when the centrifugal force of the mercury in the basin drives the mercury out through a valve on the edge of the basin, and leaves a vacuum behind. The mercury, as it escapes from the basin, falls into a reservoir communicating with the bottom of the spiral groove, through which it is forced by the pressure of the atmosphere with such velocity that the reaction of the sides of the groove causes the tube and the attached basin to revolve with great momentum, evolving new centrifugal force by which the vacuum is perpetuated. Mr. Sawyer supposes that the centrifugal force of the revolving mercury is sufficient to maintain its own revolution unimpaired, and leave a large surplus capable of being applied to any useful purpose. This conclusion is founded upon the computations of Professor Bull. Professor Bull has computed that a wheel 16 inches in diameter, and weighing 531 pounds, revolving 25 times in 10 seconds, will have a centrifugal force of 2,716 pounds; and that this velocity may be produced by a power of 166 pounds applied 1-1/2 inches from the centre, or a power of 452 pounds acting on the spiral groove already mentioned. Hence, says Mr. Sawyer, we have "a clear surplus of 2,264 pounds more than is required to turn the wheel." If this were so, it would constitute the most beautiful perpetual motion ever dreamed of by the visionary. Professor Loomis discusses the subject at length, and his chief objection may be summed up as follows: According to Sawyer &, Co.'s own data, the centrifugal force of a revolving wheel exceeds the power required to produce the rotation only at exceedingly high velocities—and in order to avail themselves of the full extent of this centrifugal force, they must employ air of such density that no vessel could possibly resist its pressure.
In the archives of Venice an interesting discovery has been made, from which it would appear that a Frenchman of the name of Gautier, professor of mathematics at Nancy, and member of the Royal Society at Paris, was the first to invent navigation by steam. In the year 1756 he submitted his plan to the society, of which he was a member, and it met with no countenance from that body. He then published a treatise on the subject, which attracted the attention of the Venetian Republic, and procured for him an invitation to the shores of the Adriatic; he went, but death soon put an end to his labors. A year or two afterwards the theory of Gautier was practically exemplified on the Seine, amidst the acclamations of the Parisians. The treatise by Gautier on "Navigation by Fire" the discovery alluded to above.
A paper was read before the British Association entitled "A Comparison of Athletic Men of Great Britain with Greek Statues," by Mr. J. B. Brent. Mr. Brent, in order to obtain those of the athletic, measured and weighed celebrated boxers, cricketers, wrestlers, rowers, pedestrians, and others. These he compared to the heights and weights of soldiers and policemen, and thence with certain celebrated Greek statues. And from such a comparison it appears that the wrestlers of Cornwall, Devon, and the north of England, are not inferior to those statues.
A letter from St. Petersburg says that the Geographical Society of that city is displaying great activity. "Scarcely has the expedition which is sent to seek out the sources of the Nile returned when the society is preparing a new expedition having for its object to explore the peninsula of Kamskatka. The Count de Czapski is to have the direction of this new attempt, and he has subscribed 20,000f. a year towards the expense."
