The impossibility of safe correlation of units necessitates a division by countries.
A problem arises because of the strong correlation between standard of living and energy consumption.
Such small granules have been observed in the sensitive cells, and there is an evident correlation between these and the power of receiving the geotropic stimulus.
One aspect of organic individuality is the correlation of variations, the fact that when one part varies, other parts vary more or less simultaneously.
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.
A similar rotation and dislocation occurs in various petrels, in correlation with the indigestible sepia-bills, &c., which these birds swallow in great quantities.
The bodywall is greatly simplified in the Gymnolaemata, in correlation with the functional importance of the skeletal part of the wall.
They were recorded in the comparatively late surviving version of the 7th century B.C., on twelve tablets, with an obvious design of correlation with the twelve divisions of the sun's annual course.
Thus the attempt to find out a constitution for the aether will involve a synthesis of intimate correlation of the various types of physical agencies, which appear so different to us mainly because we perceive them through different senses.
Beginning in 1793 he boldly advocated evolution, and further elaborated five great principles--namely, the method of comparison of extinct and existing forms, the broad sequence of formations and succession of epochs, the correlation of geological horizons by means of fossils, the climatic or environmental changes as influencing the development of species, the inheritance of the bodily modifications caused by change of habit and habitat.
His famous " law of correlation," which by its apparent brilliancy added enormously to his prestige, is not supported by modern philosophical anatomy, and his services to stratigraphy were diminished by his generalizations as to a succession of sudden extinctions and renovations of life.
Similarly, there is no correlation in the rate of evolution either of adjoining or of separated parts; the middle digit of the foot of the three-toed horse is accelerated in development, while the lateral digits on either side are retarded.
- Diagram demonstrating that there are an indefinite number of combinations of various adaptive types of limbs and feet with various adaptive types of teeth, and that there is no fixed law of correlation between the two series of adaptations.
All the great systems of rock formations are represented in the United States, though close correlation with the systems of Europe is not always possible.
The number of systems is not everywhere the same, nor are they everywhere alike, and their definite correlation with one another is not possible now, and may never be.
The consequence is that all the world admitted into his philosophy is what he called the " empirio-critical essential co-ordination " (empirio-kritische Prinzipialkoordination), an inseparable correlation of central part and counterpart, of ego and environment.
The " true account " of the world in his own words is " that the concrete whole, which may be described indifferently as an eternal intelligence realized in the related facts of the world, or as a system of related facts rendered possible by such an intelligence, partially and gradually reproduces itself in us, communicating piecemeal, but in inseparable correlation, understanding and the facts understood, experience and the experienced world."
The groups of organisms utilized for zoning and correlation by different workers include brachiopods, pelecypods, cephalopods, corals, fishes and plants; and the results of the comparison of the faunas and floras of different areas where Carboniferous rocks occur are generalized in the table below.
The relative value of any group of animals or plants for the correlation of distant areas must vary greatly with the varying conditions of sedimentation and with the precise definition of the zonal species and with many other factors.
Theism si'ggests at the very outset that we should rather expect to find a correlation between the two.
With the exception of these forms, reduced for the most part in correlation with a semi-parasitic mode of life, the tentacles are usually numerous.
It has been the habit of biologists to use the terms variation, selection, elimination, correlation and so forth, vaguely; the new school, which has been strongly reinforced from the side of physical science, insists on quantitative measurements of the terms. When the anatomist says that one race is characterized by long heads, another by round heads, the biometricist demands numbers and percentages.
Thus it has come to pass that the muscles of the hind limbs are, like their framework, more easily compared with those of reptiles and mammals than are the wings, whilst within the class of birds they show an enormous amount of variation in direct correlation with their manifold requirements.
It is, however, fair to state that his system was not built entirely upon these muscular variations, but rather upon a more laborious combination of anatomical characters, which were so selected that they presumably could not stand in direct correlation with each other, notably the oil-gland, caeca, carotids, nasal bones and above all, the muscles of the thigh.
The larvae are stout and soft-skinned, with short legs in correlation with their burrowing habit.
In the following year .another set of hints - of a kind so different that probably no one then living would have thought it possible that they should ever be brought in correlation with those of Nitzsch - are contained in a memoir on Fishes contributed to the tenth volume of the Annales du Museum d'histoire naturelle of Paris by Etienne Geoffroy St-Hilaire in 1807.1 Here we have it stated as a general truth (p. too) that young birds have the ' sternum formed of five separate pieces - one in the middle, being its keel, and two " annexes " on each side to which the ribs are .articulated - all, however, finally uniting to form the single " breast-bone."
Mr Hooker has shown with reference to the wheat market how close is the correlation between prices in different places,' and the same has been observed of the cotton market, though the Conceivably some indication of the working of " futures " might be gleaned from observation of the relations of near and distant " futures " to one another and of both to spot."
Chemistry and physics, however, meet on common ground in a well-defined branch of science, named physical chemistry, which is primarily concerned with the correlation of physical properties and chemical composition, and, more generally, with the elucidation of natural phenomena on the molecular theory.
Deferring the detailed discussion of cyclic or ringed hydrocarbons, a correlation of the various types or classes of compounds which may be derived from hydrocarbon nuclei will now be given.
In the investigation of these relations, the physicist and chemist meet on common ground; this union has been attended by fruitful and far-reaching results, and the correlation of physical properties and chemical composition is one of the most important ramifications of physical chemistry.
It is to be noted that although the correlation of melting-point with constitution has not been developed to such an extent as the chemical significance of other physical properties, the melting-point is the most valuable test of the purity of a substance, a circumstance due in considerable measure to the fact that impurities always tend to lower the melting-point.
The tail and ears are generally very long; while, in correlation with the size of the latter, the auditory bullae of the skull are also large.
They have long hind limbs, large eyes and ears; and in correlation with the latter an enlarged auditory bulla to the skull, which is hollow and divided into a tympanic and a mastoid portion.
This wide range is open to doubt as to the correlation of some of the beds involved.
The Proterozoic formations have yielded a few fossils in several places, especially Montana and northern Arizona; but they are so imperfect, their numbers, whether of individuals or of species, are so small, and the localities where they occur so few, that they are of little service in correlation throughout the United States.
