But this cue was all that he required. A clever scheme! Pax had formed layers of molecular thickness of two different metals in alternation by the to-and-fro swing of his charging current. When the battery discharged the metals went into solution, each plate becoming alternately positive and negative.

Though she does not sing to House People, how do we know but what she whispers a little lullaby like this, on stormy nights, to her nestlings? "Rains beat! Winds blow! Safe the nest in the elm tree. Days come! Nights go! Birds at rest in the elm tree. To-and-fro, to-a-n-d-fro, Safe are we from every foe Orioles in the elm tree. Cats come! Cats go! Lullaby in the elm tree!

Now the vibrations of the tympanic membrane are passed along the chain of bones attached to its inner surface and reach the stirrup bone. The stirrup now performs a to-and-fro movement at the oval window, passing the auditory impulse inwards to the internal ear. The membranous labyrinth occupies the central portion of the vestibule and the passages leading from it.

It is evident that in this arrangement it is not intended to keep the long and the short fibers separate, but to utilize them all in the formation of the yarn. Instead of the sliver being wound upon the roller in the usual way, it runs upon a sheet of linen, P, as in the case of carding for felt, with a to-and-fro motion in the direction of the axis of the rollers.

The Baron stared at him for some moments, at the solid, capable, biddable creature he was, stable and passive in the jar of the overturned world. He pointed to the table. "Sit there, my good Haase," he ordered. "I will dictate you a telegram. Not code this time, plain German!" He resumed his to-and-fro walk while Herr Haase established himself.

The kind of motion which is thus transformed is not even a to-and-fro swing of an atom, or molecule, like the swing of a pendulum bob, but that due to a change of form of the atoms within the molecule, otherwise there could be no such thing as spectrum analysis. Vibratory motion of the matter becomes undulatory motion in the ether.

So very quiet good-bye kisses full of sweet promises were given and John turned towards Lucy. She sat in her low nursing-chair slowly rocking to-and-fro the baby in her arms. Her face was bent and smiling above it and she was singing sweet and singing low a strain from a pretty lullaby,

The equilibrists mentioned thus far have invariably used a tightly stretched rope or wire; but there are a number of persons who perform feats, of course not of such magnitude, on a slack wire, in which they have to defy not only the force of gravity, but the to-and-fro motion of the cable as well. It is particularly with the Oriental performers that we see this exhibition.

It dilates and contracts like ours, sucks in the blood by means of side-valves, which act as our own do, and drives it back again into the mass by that valve at its extremities, which opens near the head. From thence arises a continued to-and-fro movement, which sends the blood from the head to the tail, and brings it back again from the tail to the head.

Like a giant of a spider at the nucleus of his web, he watched the broad fan of radiant threads, and the hovering of filmy woof, but without the mild philosophy of that spider, who is versed in the very sad capriciousness of flies. "Send Admiral Decres to me," the Emperor shouted, as he laid down his telescope and returned to his petulant to-and-fro.
