Daru the complete plan of the campaign against Austria): "Order of marches, their duration, places of convergence or meeting of the columns, attacks in full force, the various movements and mistakes of the enemy, all, in this rapid dictation, was foreseen two months beforehand and at a distance of two hundred leagues....

... each act of seeing, it becomes the task of the superior and inferior recti muscles to keep the eyes in the same plane, and of the external and internal recti muscles to give just the right amount of convergence. If slight pressure is exerted against one of the eyes, the action of the muscles is interfered with and, as a consequence, one sees double. The advantages of two eyes over one in seeing lie in the greater distinctness and broader range of vision and in the greater correctness of judgments ...

... no communication with one another, and knowing nothing of one another's statements, the points in which they all agreed became more and more evidently true. And when this concurrence of testimony, this convergence upon what were substantially the same broad facts, showed itself in hundreds of depositions, the truth of those broad facts stood out beyond question. The force of the evidence is cumulative. Its worth can be estimated only by perusing the testimony as a whole. If any further confirmation had ...

... effect by concave mirrors, of a figure formed by the revolution of an isoceles rectangular triangle, all the lines from the circumference of which meeting in a center, by holding it in the light of the sun they can collect and concentrate all its rays at this one point of convergence; where the air will now become rarefied, and any light, dry, combustible matter will kindle as soon as applied, under the effect of the rays, which here acquire the substance and active force of fire. Some are of opinion that these vestals ...

... complete the fossil skeleton of a vertebrate, or the remains of an arthropod, the more complete will be our conception of the form of the extinct organism. It may be misleading in the numerous cases of convergence and of generalized forms which now abound in our palaeontological collections. We can well understand how guarded one must be in working out the restorations of dinosaurs and fossil birds, of the Permian and Triassic theromorphs, and the Tertiary creodonts ...

... did not march towards it, but crossed the river with difficulty in the higher reaches by a ford. And it may also be urged that a bridge across the Rhine was equally unknown in that time. But, the bridge once established, it could not fail to become the main point of convergence for the commerce of Southern England, and indeed for much of that which proceeded from the North upon its way to the Continent. Such an obstacle would oppose itself to every invasion, and did, in fact, oppose itself to more ...

... system, the nerves taking the place of the wires, and being so arranged that all currents of 'animal spirit' flowing in them converged upon a single unit, a gland at the base of the brain. In this unit, or in the convergence of all the motions upon it, the 'unity' of the body virtually consisted; and the soul was incarnate, not in the plurality of members (for how could it, being one, indwell many things?), but in the ...

... tortuous course, but still seeming as if it intended ultimately to mingle its waters with those of the Mediterranean. It is not till about Balis, in lat. 36 deg., that this intention appears to be finally relinquished, and the convergence of the two streams begins. The Euphrates at first flows nearly due east, but soon takes a course which is, with few and unimportant deflections, about south-east, as far as Suk-es-Sheioukh, after which it runs a little north of east to Kurnah.

Doubtless, in the elaboration of the common result, each (individual) bears his due share; but the private sentiments do not become social except by combining under the action of the forces sui generis which association develops. As a result of these ...

Not by direct light, but by various reflex lights, and convergence of probabilities old and new, which become the stronger the better they are examined; and may be considered as amounting to what is called a moral certainty,—"certain" enough for an inquiry of that significance. ...

... occasional footstep. The police who, as Jimmie Dale understood quite clearly now, had run into the Mole's gang as the two converged at the rear of the Mole's house, had evidently now got the better of the gangsters. And that convergence, too, explained why the Pippin had accompanied him so meekly toward the shed—the Pippin's one aim and object at that moment had been to avoid the police! He leaned suddenly forward over the man—the Pippin was going fast now. There was one thing yet, a thing that was vital, paramount, ...

... amiably, affecting not to hear; and when this pretence became so obvious that even a dog could keep it up no longer, sat down in a corner, facing it, his back to his master, and his head perpendicular, nose upward, supported by the convergence of the two walls. This, from a dog, is the last word, the comble of the immutable. Penrod commanded, stormed, tried gentleness; persuaded with honeyed words and pictured rewards. Duke's eyes looked backward; otherwise he moved not. Time elapsed. Penrod stooped to flattery, finally ...

... of the child," we see at once that the meeting-place of gift and occupation has been reached. The two series are now in fact so nearly one that the point is much more often used for occupation work than as a gift. This convergence of the series in regard to their practical use was first noted in the tablets, and has grown more and more marked ...

I do not think that it is the sole explanation—for indeed in all or nearly all these cases the acceptance of a myth seems to depend not upon a single argument but upon the convergence of a number of meanings and reasons in the same symbol. But certainly the fact mentioned above is curious, and its importance is ...

Thus, on taking A' instead of A in the case of Fig. 3, they approach, while the contrary happens on choosing the point A". It is clear that the different positions that a needle A may take are found on a straight line which runs to the ...

... that this has been done by successive sets of animals in succeeding ages. Most notably the mammals repeat all the experiments of reptiles on a higher turn of the spiral. Thus arises what is called convergence, the superficial resemblance of unrelated types, like whales and fishes, the resemblance being due to the fact that the different types are similarly adapted to similar conditions of life. Professor H. ...

... but Wilkinson's show the warp threads converging towards the breast beam; Wilkinson shows them parallel and in Lepsius their convergence is excessive. There should be a slight convergence shown, as in the course of weaving the threads get drawn in, and in later forms of looms in semi-civilised countries we find an endeavour to counteract this tendency by the use of a tool ...

... comedy of Athens coincide. In this also alone did the Greek tragedy and comedy unite; in every thing else they were exactly opposed to each other. Tragedy is poetry in its deepest earnest; comedy is poetry in unlimited jest. Earnestness consists in the direction and convergence of all the powers of the soul to one aim, and in the voluntary restraint of its activity in consequence; the opposite, therefore, lies in the apparent abandonment of all definite aim or end, and in the removal of all bounds in the exercise of the mind,—attaining ...

... defines their meaning. Truth absolute, he says, means an ideal set of formulations towards which all opinions may in the long run of experience be expected to converge. In this definition of absolute truth he not only postulates that there is a tendency to such convergence of opinions, to such ultimate consensus, but he postulates the other factors of his definition equally, borrowing them by anticipation from the true conclusions expected to be reached. He postulates the existence ...

... features of the face, in the form of the nose, in the structure of the external ear, man resembles the apes. The arrangement of the hair in man has also much in common with the apes; as also the occurrence of hair on the forehead of the human embryo, the beard, the convergence of the hair of the upper and under arm towards the elbow, which occurs not only in the anthropoid apes, but also in some American monkeys.

As we drove out of Limerick past the great pig-slaughtering and curing houses, we soon became aware that an immense convergence of the farming interest on Limerick was taking place. Car-load after car-load of well-dressed people passed us, and then came horsemen riding in couples or by half-dozens. For the most part the cavaliers were very ...

... dark forms around it were those of men—mounted and afoot! It must have been the last waggon of the train: since no other could be seen; and as it appeared at the very end of the valley—in the angle formed by the convergence of the cliffs—we concluded that there the canon opened into which the rest had entered. Whether the waggon seen was moving onward, we did not stay to determine. The caravan was in sight; and this, acting upon us like an electric influence, ...

She watches "the stealthy convergence of human fates," the intersection at various angles of the planes of character, the power {279} that the lower nature has to thwart, stupefy, or corrupt the higher, which has become entangled with it in the mesh of destiny. ...

The problem of withdrawing in safety was rendered insoluble by the battles of the first week in November and the consequent convergence of the Allies on Germany's remaining lines of communication.

Towards the end of October the Americans had surmounted their difficulties of transport and organization, and were breaking down the German resistance, ...

... Mediterranean is a sea which, by reason of its confined nature, is particularly suited for operations by submarines against trade. Its narrowness at various points, such as the Straits of Gibraltar, the Malta Channel, the Straits of Messina, and the passages to the AEgean cause such convergence of trade as to make it a very simple matter for a submarine to operate with success. Evasion by change of route is almost impossible. Operations designed to prevent the exit of submarines from the Adriatic were difficult, because the depth of water in the Straits of Otranto ...
