ever heard of upon the face of the Earth.
I asked what was the name of the usurping tyrant.
As well as the Count could recollect, it was Mob.
Not knowing what to say to this, I raised my voice, and deplored the Egyptian ignorance of steam.
The Count looked at me with much astonishment, but made no answer. The silent gentleman, however, gave me a violent nudge in the ribs with his elbows—told me I had sufficiently exposed myself for once- and demanded if I was really such a fool as not to know that the modern steam-engine is derived from the invention of Hero, through Solomon de Caus.
We were now in imminent danger of being discomfited; but, as good luck would have it, Doctor Ponnonner, having rallied, returned to our rescue, and inquired if the people of Egypt would seriously pretend to rival the moderns in the all—important particular of dress.
The Count, at this, glanced downward to the straps of his pantaloons, and then taking hold of the end of one of his coat-tails, held it up close to his eyes for some minutes. Letting it fall, at last, his mouth extended itself very gradually from ear to ear; but I do not remember that he said any thing in the way of reply.
Hereupon we recovered our spirits, and the Doctor, approaching the Mummy with great dignity, desired it to say candidly, upon its honor as a gentleman, if the Egyptians had comprehended, at any period, the manufacture of either Ponnonner's lozenges or Brandreth's pills.
We looked, with profound anxiety, for an answer—but in vain. It was not forthcoming. The Egyptian blushed and hung down his head. Never was triumph more consummate; never was defeat borne with so ill a grace. Indeed, I could not endure the spectacle of the poor Mummy's mortification. I reached my hat, bowed to him stiffly, and took leave.
Upon getting home I found it past four o'clock, and went immediately to bed. It is now ten A.M. I have been up since seven, penning these memoranda for the benefit of my family and of mankind. The former I shall behold no more. My wife is a shrew. The truth is, I am heartily sick of this life and of the nineteenth century in general. I am convinced that every thing is going wrong. Besides, I am anxious to know who will be President in 2045. As soon, therefore, as I shave and swallow a cup of coffee, I shall just step over to Ponnonner's and get embalmed for a couple of hundred years.

The Balloon Hoax
[Astounding News by Express, via Norfolk!—The Atlantic crossed in Three Days! Signal Triumph of Mr. Monck Mason's Flying Machine!– Arrival at Sullivan's Island, near Charleston, S.C., of Mr. Mason, Mr. Robert Holland, Mr. Henson, Mr. Harrison Ainsworth, and four others, in the Steering Balloon, "Victoria," after a passage of Seventy-five Hours from Land to Land! Full Particulars of the Voyage!
The subjoined jeu d'esprit with the preceding heading in magnificent capitals, well interspersed with notes of admiration, was originally published, as matter of fact, in the "New-York Sun," a daily newspaper, and therein fully subserved the purpose of creating indigestible aliment for the quid-nuncs during the few hours intervening between a couple of the Charleston mails. The rush for the "sole paper which had the news," was something beyond even the prodigious; and, in fact, if (as some assert) the "Victoria" did not absolutely accomplish the voyage recorded, it will be difficult to assign a reason why she should not have accomplished it.]
The great problem is at length solved! The air, as well as the earth and the ocean, has been subdued by science, and will become a common and convenient highway for mankind. The Atlantic has been actually crossed in a Balloon! and this too without difficulty—without any great apparent danger—with thorough control of the machine—and in the inconceivably brief period of seventy-five hours from shore to shore! By the energy of an agent at Charleston, S.C., we are enabled to be the first to furnish the public with a detailed account of this most extraordinary voyage, which was performed between Saturday, the 6th instant, at 11, A.M., and 2, P.M., on Tuesday, the 9th instant, by Sir Everard Bringhurst; Mr. Osborne, a nephew of Lord Bentinck's; Mr. Monck Mason and Mr. Robert Holland, the well-known æronauts; Mr. Harrison Ainsworth, author of "Jack Sheppard," &c.; and Mr. Henson, the projector of the late unsuccessful flying machine—with two seamen from Woolwich—in all, eight persons. The particulars furnished below may be relied on as authentic and accurate in every respect, as, with a slight exception, they are copied verbatim from the joint diaries of Mr. Monck Mason and Mr. Harrison Ainsworth, to whose politeness our agent is also indebted for much verbal information respecting the balloon itself, its construction, and other matters of interest. The only alteration in the MS. received, has been made for the purpose of throwing the hurried account of our agent, Mr. Forsyth, in a connected and intelligible form.
THE BALLOON.
Two very decided failures, of late—those of Mr. Henson and Sir George Cayley—had much weakened the public interest in the subject of aerial navigation. Mr. Henson's scheme (which at first was considered very feasible even by men of science,) was founded upon the principle of an inclined plane, started from an eminence by an extrinsic force, applied and continued by the revolution of impinging vanes, in form and number resembling the vanes of a windmill. But, in all the experiments made with models at the Adelaide Gallery, it was found that the operation of these fans not only did not propel the machine, but actually impeded its flight. The only propelling force it ever exhibited, was the mere impetus acquired from the descent of the inclined plane; and this impetuscarried the machine farther when the vanes were at rest, than when they were in motion—a fact which sufficiently demonstrates their inutility; and in the absence of the propelling, which was also the sustaining power, the whole fabric would necessarily descend. This consideration led Sir George Cayley to think only of adapting a propeller to some machine having of itself an independent power of support—in a word, to a balloon; the idea, however, being novel, or original, with Sir George, only so far as regards the mode of its application to practice. He exhibited a model of his invention at the Polytechnic Institution. The propelling principle, or power, was here, also, applied to interrupted surfaces, or vanes, put in revolution. These vanes were four in number, but were found entirely ineffectual in moving the balloon, or in aiding its ascending power. The whole project was thus a complete failure.
It was at this juncture that Mr. Monck Mason (whose voyage from Dover to Weilburg in the balloon, "Nassau," occasioned so much excitement in 1837,) conceived the idea of employing the principle of the Archimedean screw for the purpose of propulsion through the air—rightly attributing the failure of Mr. Henson's scheme, and of Sir George Cayley's, to the interruption of surface in the independent vanes. He made the first public experiment at Willis's Rooms, but afterwards removed his model to the Adelaide Gallery.
Like Sir George Cayley's balloon, his own was an ellipsoid. Its length was thirteen feet six inches—height, six feet eight inches. It contained about three hundred and twenty cubic feet of gas, which, if pure hydrogen, would support twenty-one pounds upon its first inflation, before the gas has time to deteriorate or escape. The weight of the whole machine and apparatus was seventeen pounds—leaving about four pounds to spare. Beneath the centre of the balloon, was a frame of light wood, about nine feet long, and rigged on to the balloon itself with a network in the customary manner. From this framework was suspended a wicker basket or car.
The screw consists of an axis of hollow brass tube, eighteen inches in length, through which, upon a semi-spiral inclined at fifteen degrees, pass a series of a steel wire radii, two feet long, and thus projecting a foot on either side. These radii are connected at the outer extremities by two bands of flattened wire—the whole in this manner forming the framework of the screw, which is completed by a covering of oiled silk cut into gores, and tightened so as to present a tolerably uniform surface. At each end of its axis this screw is supported by pillars of hollow brass tube descending from the hoop. In the lower ends of these tubes are holes in which the pivots of the axis revolve. From the end of the axis which is next the car, proceeds a shaft of steel, connecting the screw with the pinion of a piece of spring machinery fixed in the car. By the operation of this spring, the screw is made to revolve with great rapidity, communicating a progressive motion to the
