The intensity of the secondary light is no longer to be arrived at by addition of individual intensities, but must be calculated with consideration of the particular phases involved.
He sprinted, geared down, and just lolled along, experimenting with his body's reaction to the various phases and ultimately pleased with its response to his multiple tests.
When sin 0 = 2A/a, the phases range one and a half periods, and there is revival of illumination.
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.
Religious feasts - with the phases of the moon among the Semites.
The idealisms of Fichte and Schelling made contributions to Hegel's thought; Krause and the Roman Catholic Baader represent parallel if minor phases of idealism.
Thirdly, those members of a group which, whilst exhibiting undoubted structural characters indicative of their proper assignment to that group, yet are simpler than and inferior in elaboration of their organization to other members of the group, are not necessarily representatives of the earlier and primitive phases in the development of the group - but are very often examples of retrogressive change or degeneration.
With such an enormous geographical range the species must of necessity present itself under a considerable number of local phases, differing from one another to a greater or less degree in the matters of size and colouring.
It is on clinical grounds that beriberi, scarlet fever, measles, &c., are recognized as belonging to the same class, and evolving in phases which differ not in intimate nature but in the more superficial and inessential characters of time, rate and polymorphism; and the impression is gaining strength that acute rheumatism belongs to the group of the infections, certain sore throats, chorea and other apparently distinct maladies being terms of this series.
In the dim light of his bedroom, she was able to make out a small symbol on the metal: a moon in two separate phases, full and crescent.
But, further, every attempt to think clearly what those relations are, what we really mean, if we talk of a fixed order of events, forces upon us the necessity of thinking also that the different things which stand in relations or the different phases which follow each other cannot be merely externally strung together or moved about by some indefinable external power, in the form of some predestination or inexorable fate.
The combination of the secondary waves which travel in the direction in question have this peculiarity: that the phases are no more distributed at random.
Xxii., xlii.-xliii., lxxiii., lxxvii., other phases of the problem are presented.
Yet it is clear from the book of Genesis alone that in the age of Priestly writers and compilers there were other phases of thought.
Little more than half a century after the overthrow of the Jewish nationality, the Mishnah was practically completed, and by this code of rabbinic law - and law is here a term which includes the social, moral and religious as well as the ritual and legal phases of human activity - the Jewish people were organized into a community, living more or less autonomously under the Sanhedrin or Synedrium and its officials.
In accordance with these more sedentary habits during the first phases of life, the characteristic pilidium larva, which is so eminently adapted for a pelagic existence, appears to have been reduced to a close-fitting exterior layer of cells, which is stripped off after the definite body-wall of the Nemertine has similarly originated out of four ingrowths from the primary epiblast.
Others devoted to special phases are the Journal fur praktische Chemie, founded by Erdmann in 1834, the Zeitschrift fur anorganische Chemie and the Zeitschrift fur physikalische Chemie.
All his novels treat of phases of American development, historical or social, and form a sort of chronological sequence.
Each discovery in turn was, according to the prevailing custom, announced to the learned world under the veil of an anagram - removed, in the case of the first, by the publication, early in 1656, of the little tract De Saturni luna observatio nova; but retained, as regards the second, until 1659, when in the Systema Saturnium the varying appearances of the so-called "triple planet" were clearly explained as the phases of a ring inclined at an angle of 28° to the ecliptic. Huygens was also in 1656 the first effective observer of the Orion nebula; he delineated the bright region still known by his name, and detected the multiple character of its nuclear star.
His part in the later phases of the Russo-Turkish struggle has never been fully explained, for with equal wisdom and generosity he declined to gratify public curiosity at the cost of some of his colleagues.
Thus, then, it seems that we have in the trilobites the representatives of the lower phases of the Arachnidan pedigree.
By some naturalists many of these local forms are regarded as specifically distinct, but it seems better and simpler to class them all as local phases or races of a single species primarily characterized by the white tip to the tail and the black or dark-brown hind surface of the ear.
A close observer of the multifarious low life of Hungary, Mikszath has, in his short stories, given a delightful yet instructive picture of all the minor varied phases of the peasant life of the Sla y s, the Palocok, the Saxons, the town artisan.
Special phases of the subject are treated under their own headings, e.g.
History There is something almost pathetic in the childish wonder and delight with which mankind in its earlier phases of civilization gathered up and treasured stories of strange animals from distant lands or deep seas, such as are recorded in the Physiologus, in Albertus Magnus, and even at the present day in the popular treatises of Japan and China.
The wave motion due to any element of the surface is called a secondary wave, and in estimating the total effect regard must be paid to the phases as well as the amplitudes of the components.
In the direction (suppose horizontal) for which n=o, /f=sin 0, the phases of the secondary waves range over a complete period when sin 0 =X/a, and, since all parts of the horizontal aperture are equally effective, there is in this direction a complete compensation and consequent absence of illumination.
This is necessarily a question of degree; but it does not require detailed calculations in order to show that the discrepancy first becomes conspicuous when the phases corresponding to the various secondary waves which travel from P to B range over a complete period.
The dark lines which separate the bands are the places at which the phases of the secondary wave range over an integral number of periods.
For example, when the direction is such that the projection of AB upon it amounts to one wave-length, the elementary components neutralize one another, because their phases are distributed symmetrically, though discontinuously, round the entire period.
If the slit be narrow, so that the arc is short, the intensity is constant over a wide range, and does not fall off to an important extent until the discrepancy of the extreme phases reaches about a quarter of a period.
Psychology is inseparably linked with physiology; and the phases of social life exhibited by animals other than man, which sometimes curiously foreshadow human policy, fall strictly within the province of the biologist.
Not only so, but the physician, thus fascinated by "types," and impressed by the silent monumentsof the pathological museum, was led to localize disease too much, to isolate the acts of nature, and to forget not only the continuity of the phases which lead up to the exemplary forms, or link them together, but to forget also that even between the types themselves relations of affinity must exist - and these oftentimes none the less intimate for apparent diversities of form, for types of widely different form may be, and indeed often are, more closely allied than types which have more superficial resemblance - and to forget, moreover, how largely negative is the process of abstraction by which types are imagined.
Thus it came about not only that classifications of disease based on superficial likeness - such as jaundice, dropsy, inflammation - were broken up, and their parts redistributed, but also that even more set diseases began to lose their settlements, and were recognized as terms of series, as transitory or culminating phases of perturbations which might be traced to their origins, and in their earlier stages perhaps withstood.
By chemical warnings the defensive processes seem to be awakened, or summoned; and when we think of the infinite variety of such possible phases, and of the multitude of corresponding defensive agents, we may form some dim notion of the complexity of the animal blood and tissues, and within them of the organic molecules.
So various are the conditions of selfregulation in various animals, both in respect of their peculiar and several modes of assimilating different foods, and of protecting themselves against particular dangers from without, that, as we might have expected, the bloods taken from different species, or even perhaps from different individuals, are found to be so divergent that the healthy serum of one species may be, and often is, poisonous to another; not so much in respect of adventitious substances, as because the phases of physiological change in different species do not harmonize; each by its peculiar needs has been modified until, in their several conditions of life, they vary so much about the mean as to have become almost if not quite alien one to another.
Both passed through phases of faith, but while even Positivism did not cool George Eliot's innate religious fervour, with George Sand religion was a passing experience, no deeper than her republicanism and less lasting than her socialism, and she lived and died a gentle savage.
If we consider a number of particles which all lie upon a primary ray, we see that the phases of the secondary vibrations which issue along this line are all the same.
Mosquitoes go through four phases: (1) ovum, (2) larva, (3) nympha, (4) complete insect.
The four phases are passed in thirty days in a favourable season, and consequently there are ordinarily four or five generations from April to September (Celli).
(After Spengel.) being formed afresh on the surface of the visceral hump. It is, then, in this sense that we may speak of primary, secondary and tertiary shells in Mollusca, recognizing the fact that they may be merely phases fused by continuity of growth so as to form but one shell, or that in other cases they may be presented to us as separate individual things, in virtue of the non-development of the later phases, or in virtue of sudden changes in the activity of the mantle-surface causing the shedding FIG.
Only the careful observation of organisms throughout the earlier phases of their life-history can the closely related factors be distinguished with any approach to scientific accuracy.
Thus the digestive function, in its largest sense, is now seen to consist, not only in preparation and supply, but in no small measure also of protective and antidotal conversions of the matters submitted to it; coincidently with agents of digestion proper are found in the circuit of normal digestion "anti-substances" which neutralize or convert peptones in their poisonous phases; an autochthonous ferment, such as rennet for instance, calling forth an anti-rennet, and so on.
Diphtheria, long no doubt a plague among mankind, was not carefully described until by Pierre Bretonneau in 1826; and since his time our conception of this disease has been extended by the study of later, secondary and incidental phases of it, such as neuritis, which had always formed part of the diphtheritic series, though the connexion had not been detected.
The obliquity, corresponding to u =7, is such that the phases of the secondary waves range over a complete period, i.e.
