For it is composed of individual events, each of which is described by four numbers, namely, three space co-ordinates x, y, z, and a time co-ordinate, the time value t. The" world" is in this sense also a continuum; for to every event there are as many "neighbouring" events (realised or at least thinkable) as we care to choose, the co-ordinates x, y, z, t of which differ by an indefinitely small amount from those of the event x, y, z, t originally considered.
Geoffroy St. Hilaire seems to entertain no doubt, that the more an organ normally differs in the different species of the same group, the more subject it is to individual anomalies.
We only give proper names to the individuals of a species when they differ inter se in practically important respects.
They looked neither older nor younger now; the beards of the aged were no whiter, nor could the creeping babe of yesterday walk on his feet to-day; it was impossible to describe in what respect they differed from the individuals on whom he had so recently bestowed a parting glance; and yet the minister's deepest sense seemed to inform him of their mutability.
Thus they all worked on, encompassed by the vast flat mead which extended to either slope of the valley--a level landscape compounded of old landscapes long forgotten, and, no doubt, differing in character very greatly from the landscape they composed now.
Federal (Federation) - a form of government in which sovereign power is formally divided - usually by means of a constitution - between a central authority and a number of constituent regions (states, colonies, or provinces) so that each region retains some management of its internal affairs; differs from a confederacy in that the central government exerts influence directly upon both individuals as well as upon the regional units.
The passage from one stage of difference to another and higher stage may be, in some cases, due merely to the long-continued action of different physical conditions in two different regions; but I have not much faith in this view; and I attribute the passage of a variety, from a state in which it differs very slightly from its parent to one in which it differs more, to the action of natural selection in accumulating (as will hereafter be more fully explained) differences of structure in certain definite directions.
Weber made the earliest experiments, later verified by Fechner, showing that the sensation of weight differs a great deal on different portions of the skin.
I have maintained throughout these lectures that the data of psychology do not differ in, their intrinsic character from the data of physics.
The Alimentive is more like the Thoracic than any other, and in the places where they differ the Alimentive gives in with better grace than other types.
