In its widest sweeps my tree-top described an arc of from twenty to thirty degrees, but I felt sure of its elastic temper, having seen others of the same species still more severely triedbent almost to the ground indeed, in heavy snowswithout breaking a fiber.

He could move over the chord, while Lee was compelled to follow the arc of the circle.

BIOT, JEAN BAPTISTE, an eminent French mathematician, astronomer, and physicist, born at Paris; professor of Physics in the College of France; took part in measuring an arc of the meridian along with Arago; made observations on the polarisation of light, and contributed numerous memoirs to scientific journals; wrote works on astronomy (1774-1862).

The first motion (the dot) is to the right of the sender, and will embrace an arc of 90°, starting with the vertical and returning to it, and will be made in a plane at right angles to the line connecting the two stations.

Q.Can you state how we may discover at what point of the stroke the eduction passage will be closed? A.To find how much before the end of the stroke the eduction passage will be closed:to the lap on the steam side add the lead, and divide the sum by half the stroke of the valve; find the arc whose sine is equal to the quotient, and add 90° to it.

Waring swept the southern arc with his glasses.

And from this onwards, we were free from molestation; though we had no knowledge but that the quietness of the weed men did but portend a fresh attack, and so, at last, it came to the dawn; and in all this time the moon came not to our help, being quite hid by the clouds which now covered the whole arc of the sky, making the dawn of a very desolate aspect.

In arc lamps the magnet for forming the arc can be composed of a closed conductor, a coil for the passage of current, and an iron wire core.

The concert-hall tune echoes down the dark street, The mothers lean out from the windows to see, While soft sounds the pat of the dancers' bare feet, And tenement babies crow loud in their glee; And labor-worn fathers are laughing and chatting, Forgot for an hour is grim poverty's thrall; There's joy here to-night, 'neath the swinging arc-light, In "Finnegan's Court," at the hand-organ ball.

This machine has been studied with a view of rendering the lamps independent; and there may be produced with it, for example, a voltaic arc of an intensity of from 250 to 600 carcels for the lighting of a courtyard, or it may be used for producing arcs of less intensity for shops, or for supplying incandescent lamps.

Grand go the years in the crescent above them; Worlds scoop their arcs, and firmaments row, Diadems drop and Doges surrender, Soundless as dots on a disk of snow.

Until after the tedious dinner, a complete rainbow of dreams spanned the arc of my brain.

After five o'clock she started home alone along the heavily shaded paths of the campus, as dim as caves in the interval before the big, winking sputtering arc-lights were flashed on.

The line A B must equal the line C D; somewhere in space must be found the centre or the focus of every curve; and every angle must subtend a certain arc, to be easily found on reference to the tables of the text-books.

; divide the lap on the eduction side by half the stroke of the valve, and find the arc whose cosine is equal to the quotient; subtract this arc from the one last obtained, and find the cosine of the remainder; subtract this cosine from 2, and multiply the remainder by half the stroke of the piston; the product is the distance of the piston from the end of the stroke when the eduction passage is closed.

It swung an arc of two hundred degrees or so, about the main body of their tillable land) rose the heavily wooded slopes of Hickory Hill.

He was already swinging up the pendulum arc.

The governor swings himself unsteadily to the right-hand railing and the long look ahead brings the twinkling arc-star of the tower light on Breezeland Inn into view.

Beginning at a spot near the edge of the cliff, he worked gradually, back and forth, in ever widening arcs, toward the pines below.

Roasting, boiling, frying, broiling, do not alone constitute the arc of cooking, otherwise the savage of the Oronoco might be maître d'hôtel with Prince Esterhazy.

In the space of four minutes they deposited thirty thousand high-explosive shells in the Boche front-line trenchesyea, distributed the same accurately and evenly along all that crowded arc.

The places designated arc all within the range of a single New Jersey county.

Posidonius, who was nearly a century later, determined the arc of a meridian between Rhodes and Alexandria to be a forty-eighth part of the whole circumference,an enormous calculation, yet a remarkable one in the infancy of astronomical science.

The difference of longitudes was determined by the transfer of chronometers by the very circuitous route from one extremity to the other; and it was necessary to divide the whole arc into four parts, and to add a small part by measure and bearing.

A black thundercloud rushed up out of the South, and seemed to leap all the arc of the sky, in a single instant.
