He then ascertained the dimensions of the orbit; and, by a comparison of the times employed by the planet to complete a whole revolution or any part of one, he discovered that the time in which Mars describes any arches of his elliptic orbit, were always to one another as the areas contained by lines drawn from the focus or the centre of the sun to the extremities of the respective arches; or, in other words, that the radius vector, or the line joining the Sun and Mars described equal areas in equal times.
In a more general case, where the planet does not revolve in a circle, but pursued an elliptic path, the moment of momentum is to be found by multiplying the planet's velocity and its mass into the perpendicular from the sun on the direction in which the planet is moving.
Instead of this being the case, the axis of rotation of the earth is tipped so that the angle between the equator and the elliptic is 23-1/2°." "I seem to remember something of the sort from my school days." "This angle of tilt may be assumed to be constant, for I won't bother with the precessions, nutations and other minor movements considered in accurate computations.
To several stage anecdotes of the actor as an excellent instructor of younger players, you refer slightingly. In reference to a very elliptic statement that, "in Hamlet Betterton benefited by Shakespeare's coaching," you write, "This is astonishing, seeing that Shakspere had been in his grave nearly twenty years when Betterton was born.
The arrangement of a furnace is very simple. It consists of a cube of masonry containing several cylindrical apertures with elliptic bases, whose large axis is paralleled with the smaller side of the masonry. This form recalls that of a crucible; and these cavities are, moreover, so named.
The passenger cars were 56 feet long and 9½ feet wide, the first class carrying 33 passengers, the second class 54, and the third class 80. They all had eight truck wheels under each, and elliptic steel springs. The freight cars were all 30 feet long and 9½ feet wide, made in a uniform manner, with eight truck wheels under each.
The phrase is elliptic; in full it would be 'cum maxime conficio orationes, nunc conficio', 'when I most of all compose speeches, I now compose them'; i.e. 'the time when I most of all compose is now'. The words cum maxime generally follow tum or nunc and add emphasis to those words, but are sometimes used alone to express the ideas 'then' and 'now' more emphatically than tum and nunc would. Cf.
These observations were continued and greatly extended by Herschel II. The elements of the elliptic orbit of the double star zeta of the Great Bear were determined by Savary, its period being fifty-eight and one-quarter years; those of another, sigma Coronae, were determined by Hind, its period being more than seven hundred and thirty-six years.
For a seventy mile-an-hour locomotive would have been monotonous and tiresome in comparison with a dash around the ice-railway track, containing 850 feet, and covering an elliptic space whose surface had a coat of ice nearly an inch thick. Over this smooth and glistening substance the bobsleigh was gliding with the speed of a toboggan and the ease of a coaster to the merry jingle of sleigh bells.
In them we find blood-vessels for the first time, distributing real blood through the body. The blood is red, and the red colouring-matter is haemoglobin, connected with elliptic discoid blood-cells, as in the Vertebrates.
