... are the best investment for the increase of national, state, and individual wealth. Then all would acknowledge the harmony of labor and capital, their ultimate association in profits for mutual benefit. This social as well as political union, together with the specializing and differentiation of pursuits, and observing duties as rights, would falsify the gloomy dogma of Malthus, founded on the doctrine of the eternal and ever-augmenting antagonism of wages and money, and solve, in favor of humanity, the great problem of the grand and glorious destiny of the masses of mankind. ...

... came to be employed in botanical classification as the name of a class, an arbitrary limitation had to be set to its signification, and this was not always in keeping with its original meaning. The absence of differentiation into root, stem and leaf which prevails among seaweeds, seems, for example, to have led Linnaeus to employ the term in the Genera Plantarum for a sub-class of Cryptogamia, the members of which presented this character in a greater or less degree. ...

... Maya: in reality there is no plurality of sound. Ram seems to have been selected as the divine name, because its brevity is an approach to this unity, but true knowledge is to understand the Letterless One, that is the real name or essence of God from which all differentiation of letters has vanished. Apart from some special metaphors the whole doctrine set forth in the Sukh Nidhan and Amar Mul is little more than a loose Vedantism, somewhat reminiscent ...

... Harbor Granger visited three of the more than two hundred auxiliary ships manned by mixed crews. On two the conditions were excellent. The commanding officer in each case had taken special (p. 149) pains to avoid racial differentiation in ratings, assignments, quarters, and messes; efficiency was superior, morale was high, and racial conflict was absent. On the third ship Negroes were separated; they were specifically assigned to a special bunk section in the general crew compartment ...

LXIII. 1906) mentions the abnormal position and abnormal narrowing of Schlemm's canal and the imperfect and insufficient differentiation of the cornea-scleral junction. In all of the cases in which the eye has been examined microscopically obliteration of Schlemm's canal has been reported. This is thought to be a defect in development. Magitot ...

... when a sufficient number of bears, from widely separated regions are examined, the various distinguishing marks are found to be inconstant and to show a tendency—exactly how strong I cannot say—to fade into one another. The differentiation of the two species seems to be as yet scarcely completed; there are more or less imperfect connecting links, and as regards the grisly it almost seems as if the specific character were still unstable. In the far northwest, in ...

The introduction of this office as a permanent feature in the government was a great event in the history of human progress.

... fundamental physiological principles apply to the lowest and to the highest animals. To all belong certain properties or qualities. As structure is differentiated, or as one animal differs from another owing to greater or less complexity of form, there is a corresponding differentiation of function, none, however, ever losing the fundamental properties of protoplasm. Each organ comes to perform some one function better than all others. This is specialization, and implies advance among animals as it ...

... formularies of the Church, confirmed by the Act of Uniformity, were very much easier to reconcile with Calvinism than with what Calvinists called idolatry, and in particular the abolition of the law of celibacy in itself had a very strong tendency to abolish the sense of differentiation between clergy and laity so essential to the old Catholic position. It may have been the consciousness of this which made Elizabeth feel and express with much freedom her own objection to married clerics. But Cecil and his party were alive to the fact that the religious ...

... nevertheless the somewhat periphrastic way of putting it, by saying that the inorganic feels but does not know, or knows only very slightly, how to differentiate its feelings, has the advantage of expressing the fact that feeling depends upon differentiation and sense of relation inter se of the things differentiated—a fact which, if never expressed, is apt ...

Von Baer's standard seems the most widely applicable and the best, namely, the amount of differentiation of the parts of the same organic being, in the adult state, as I should be inclined to add, and their specialisation for different functions; or, as Milne Edwards would express it, the completeness of the division ...

With faith in Evolution unshaken—if indeed the word faith can be used in application to that which is certain—we look on the manner and causation of adapted differentiation as still wholly mysterious.

However this may be, it is beyond question that during the earlier years of the first period of childhood the differences between the sexes are comparatively trifling. But towards the end of this period, sexual differentiation becomes more marked. According to Stratz, it is at this time that the characteristic form of the lower half of the body develops. The thighs and the hips of the young girl exhibit a somewhat more marked deposit of fat than is seen in the boy ...

Embryology proves that every higher form of individual life becomes what it is by a process of gradual differentiation from an extremely low form; palaeontology proves, in some cases, and renders probable in all, that the oldest types of a group are the lowest; and that they have been followed by a gradual succession of more and ...

The trend of evolutionary forces through long centuries of human development has been on the whole in this second direction, has been towards differentiation. [Footnote: See Havelock Ellis's Man and Woman.] An adult white woman differs far more from a white man than a negress or pigmy woman from her equivalent male. The education, the mental disposition, of a white or Asiatic woman, reeks of sex; her modesty, her decorum is not to ignore sex ...

Half a century ago, before the institution of properly organised dog shows drew particular attention to the differentiation of breeds, the generic term "terrier" without distinction was applied to all "earth dogs," and the consideration of colour and size was the only common rule observed in breeding. But it would not be difficult to prove that a white terrier resembling the one now ...

This is a real distinction also, although somewhat more subtle, perhaps, than the ones previously given. Therefore, the differentiation made by the German ethnographers between wild people and the cultured peoples is, in the main, right; but it does not admit of any sharp line of distinction between the two.

These people, although presenting a series of interesting problems to the ethnologist, both from their insular position, and their differentiation from any of the mainland peoples, are still but little known. To a great extent this has arisen from their exclusiveness, and their total lack of enthusiasm in trade matters, a thing that differentiates them more than any other characteristic from the ...

The uniformity of the spirit world, which is the characteristic trait of primitive Animism, gave way to a differentiation regulated by the political development and the social growth of Babylonia. The more important natural forces became gods, and the inferior ones were, as a general thing, relegated to the secondary position of mere ...

... Nothing can extinguish science except an invasion of barbarians, and the barbarians that science has left alive would hardly suffice. Art has its limitations, science has none. It would, however, be vain to pursue our differentiation any further. It must be clear that what are most opposed in this world are art and science; therefore—I think I can say therefore—all the arguments I used to show that a British Luxembourg would ...

The fin is more primitive than the limb; the limbs themselves display a constantly increasing differentiation of parts from the batrachian to the mammalian.

The arched foot, too, comes ...

... we should find comparative prosperity prevailing among all Seminole families; and this is the fact. Much of the Indian's labor is wasted through his ignorance of the ways by which it might be economized. He has no labor saving or labor multiplying machines. There is but little differentiation of function in either family or tribe. Each worker does all kinds of work. Men give themselves to the hunt, women to the house, and both to the field. But men may be found sometimes at the cooking pot or toasting stick and women may be seen taking care of cattle and horses. Men ...

Assuming that conditions which permit genetic exchange between populations of turtles in the Salado drainage system differ in no major respect from conditions in other parts of the range of Pseudemys scripta, it is logical to suppose that the differentiation of P. s. taylori at Cuatro Cienegas was preceded by the isolation of a population in ...

He has implied that the critical climatic change occurred during post-Wisconsin times, and that the isolation of these populations occurred so recently that no morphological differentiation has resulted in them. Inasmuch as the species is widely distributed in Mexico, the southwestern United States, and in California, and has been recorded from the Pleistocene of California (Hay, 1927:323), it is reasonable to suppose that the species immigrated into Kansas from the ...

To start with, no one ever knew of a community all of whose wants were satisfied: in fact, civilization is constantly leading us into new fields of enjoyment, and results in a constant differentiation of new desires. To satisfy these wants is the spring to nearly all production and industry. There can, therefore, be no stop to production arising from lack of desire for commodities. "The limit of wealth is never deficiency of consumers," ...

His observations on the igneous rocks of south Tirol compared with those of Christiania afford much information on the relations of the granitic and basic rocks.

He dealt also with the Palaeozoic rocks of Norway, and with the late glacial and post-glacial changes ...

... of the abnormal cases, any two self-impotent plants can reciprocally fertilize each other, we may infer that a very slight difference in the nature of their sexual elements suffices to give fertility; but in other instances, as with some Passifloras and the hybrid Gladioli, a greater degree of differentiation appears to be necessary, for with these plants fertility is gained only by the union of distinct species, or of hybrids of distinct parentage. These facts all point to the same general conclusion, namely, that good is derived from a cross between individuals, which either innately, or ...

These quantities are "predestined in the germ itself" which gives rise to each individual. ...

In Germany his later speeches, in which he drew a distinction between the German people and the Imperial Government, were regarded as hypocrisy.
