The observation of the existence of an analogy between the series of gradations presented by the species which compose any great group of animals or plants, and the series of embryonic conditions of the highest members of that group.
It results that besides a horizontal distribution of plants, there is also an altitudinal: a fact of cardinal importance, the first observation of which has been attributed to Tournefort.
The danger lies not in forming such hypotheses, but in regarding them as final, or as more than an attempt to throw light upon our observation of the phenomena.
The contrast between a campaign of Cromwell's and one of Turenne's is far more than remarkable, and the observation of a military critic who maintains that Cromwell's art of war was two centuries in advance of its time, finds universal acceptance.
The observation of the gradations of structure, from extreme simplicity to very great complexity, presented by living things, and of the relation of these graduated forms to one another.
The observation of the effects of varying conditions in modifying living organisms.
If we have a large range of examples, if our observation is constantly directed to seeking the correlation of cause and effect in people's actions, their actions appear to us more under compulsion and less free the more correctly we connect the effects with the causes.
If we examined simple actions and had a vast number of such actions under observation, our conception of their inevitability would be still greater.
To study the laws of history we must completely change the subject of our observation, must leave aside kings, ministers, and generals, and study the common, infinitesimally small elements by which the masses are moved.
The observation that large groups of species of widely different habits present the same fundamental plan of structure; and that parts of the same animal or plant, the functions of which are very different, likewise exhibit modifications of a common plan.
It is merely necessary to select some larger or smaller unit as the subject of observation--as criticism has every right to do, seeing that whatever unit history observes must always be arbitrarily selected.
Pierre wished to make a remark, for the conversation interested him, but Anna Pavlovna, who had him under observation, interrupted:
(With this method of observation it often happens that the observer, influenced by the direction he himself prefers, regards those as leaders who, owing to the people's change of direction, are no longer in front, but on one side, or even in the rear.)
Aside from our personal observation that he was a first class son of a bitch, everything else about him came from Edith.
His own observation, and the reports of Mersenne, furnished his data.
The notion that all the kinds of animals and plants may have come into existence by the growth and modification of primordial germs is as old as speculative thought; but the modern scientific form of the doctrine can be traced historically to the influence of several converging lines of philosophical speculation and of physical observation, none of which go further back than the 17th century.
The distinction between the old and new method of observation may thus, in one sense, be described as the difference between shooting at a moving object and in shooting at one at rest.
This observation led him to further work, and he succeeded in showing that in vascular organs the presence of cells in inflammatory exudates is not the result of exudation but of multiplication of pre-existing cells.
The "wisdom" personified by the moon-god is likewise an expression of the science of astrology in which the observation of the moon's phases is so important a factor.
The observation of the existence of structures, in a rudimentary and apparently useless condition, in one species of a group, which are fully developed and have definite functions in other species of the same group.
The observation of the facts of the geological succession of the forms of life.
From the nature of the case, this view is not, and could not be, based upon actual observation, nor is it universally accepted; however, it seems to correspond more closely than any other to the facts of comparative morphology.
Nicholas noticed this, as he noticed every shade of Princess Mary's character with an observation unusual to him, and everything confirmed his conviction that she was a quite unusual and extraordinary being.
The farther back in history the object of our observation lies, the more doubtful does the free will of those concerned in the event become and the more manifest the law of inevitability.
The observation of the facts of geographical distribution.

Not letting the abbe and Pierre escape, Anna Pavlovna, the more conveniently to keep them under observation, brought them into the larger circle.

You can be a subsistence farmer and perhaps produce some excess, but given the prior observation about the fundamental volatility of farming, you will always be at risk of not producing enough.
Ordinary observation of the landscape shows that there is another part, highly variable from day to day, and due to suspended matter, much of which is fine enough to scatter light of blue quality.
Thomson (Lord Kelvin) observed in 1863 3 that when a condenser is charged or discharged, a sharp click is heard, and a similar observation was made by Cromwell F.
It has been a feature of great promise in recent contributions to the theory of evolution, that such contributions have received attention almost directly in proportion to the new methods of observation and the new series of facts with which they have come.
Starting from an observation of Marconi's, a number of interesting facts have been accumulated on the absorbing effect of sunlight on the propagation of long Hertzian waves through space, and on the disturbing effects of atmospheric electricity as well as upon the influence of earth curvature and obstacles of various kinds interposed in the line between the sending and transmitting stations.4 Electric wave telegraphy has revolutionized our means of communication from place to place on the surface of the earth, making it possible to communicate instantly and certainly between places separated by several thousand miles, whilst The Electrician, 1904, 5 2, p. 407, or German Pat.
