Already methinks I discern a weakness in the grasp of

mathematical truth at the present time as compared with the more robust intellect of our ancestors three hundred years ago.

This puzzling person had the air of a

mathematical professor lecturing to his pupils.

The pendulum beat the seconds, which each player eagerly counted, as he listened, with

mathematical regularity.

You know of course that a

mathematical line, a line of thickness NIL, has no real existence.

The Martians seem to have calculated their descent with amazing subtlety--their

mathematical learning is evidently far in excess of ours--and to have carried out their prepara- tions with a well-nigh perfect unanimity.

Then--this is all what you say--new economic relations will be established, all ready-made and worked out with

mathematical exactitude, so that every possible question will vanish in the twinkling of an eye, simply because every possible answer to it will be provided.

Dantes possessed a prodigious memory, combined with an astonishing quickness and readiness of conception; the

mathematical turn of his mind rendered him apt at all kinds of calculation, while his naturally poetical feelings threw a light and pleasing veil over the dry reality of arithmetical computation, or the rigid severity of geometry.

At one place, they observed a field decorated with buffalo skulls, arranged in circles, curves, and other

mathematical figures, as if for some mystic rite or ceremony.

At first, no result at all crowned my efforts, though I 'divided my swift mind,' now hither, now thither, in a way that I felt sure would have made AEneas green with envy: but the dimly-seen oval remained as provokingly blank as ever--a mere Ellipse, as if in some

mathematical diagram, without even the Foci that might be made to do duty as a nose and a mouth.

The faculty of re-solution is possibly much invigorated by

mathematical study, and especially by that highest branch of it which, unjustly, and merely on account of its retrograde operations, has been called, as if par excellence, analysis.

The tree is old and decayed, and it is gradually weakened by the frosts, until a line drawn from the centre of gravity falls without its base, and then the tree comes of a certainty; and I should like to know what greater compulsion there can be for any thing than a

mathematical certainty.

It is further recorded in the same books that he showed a great aptitude for

mathematical studies as well as map-making, and carried away a prize (The Life of Lord Lawrence, tree-calf, two vols.
