Página 74 - ... that changes of structure caused by changes of action, must also be transmitted, however obscurely, from one generation to another, appears to be a deduction from first principles— or if not a specific deduction, still, a general implication.
Página 75 - A' must be changed in all its functions; then the offspring of A' cannot be the same as they would have been had it retained the form A. It involves a denial of the persistence of force to say that A maybe changed into A', and may yet beget offspring exactly like those it would have begotten had it not been so changed.
Página 294 - THERE rolls the deep where grew the tree. O earth, what changes hast thou seen! There where the long street roars, hath been The stillness of the central sea. The hills are shadows, and they flow From form to form, and nothing stands; They melt like mist, the solid lands, Like clouds they shape themselves and go.

Página 11 - This differential and shearing movement, as I think, gathered the stratum of englacial drift into the great lenticular masses or sometimes longer ridges of the drumlins, thinly underlain by ice and overridden by the upper ice flowing downward to the boundary and bringing with it the formerly higher part of the drift stratum to be added to these growing drift accumulations. The courses of the glacial currents and their convergences to the places occupied by the drumlins were apparently not determined...
Página 91 - ... namely, that heredity is a form of unconscious organic memory, and this, from my point of view, is the only satisfactory one yet brought forward. Heredity is obviously manifested, for the most part, in the developmental results of growth and appears chiefly in the cytoplasmic structures which Dr. Minot so clearly places before us as constantly increasing with age while the comparative size of the nucleus which represents the power of growth force decreases. Whether this be granted or not, it...
Página 151 - When we recall the impression of a word or sentence, if we do not speak it out, we feel the twitter of the organs just about to come to that point. The articulating parts — the larynx, the tongue, the lips — are all sensibly excited; a suppressed articulation is in fact the material of our recollection, the intellectual manifestation, the idea of...
Página 108 - Wiirtenberger as the sole discoverer of these phenomena and of the law of tachygenesis. Wiirtenberger's work was apparently independent, and it has higher value on that account, but it needs rectification from a historical point of view. Buckman and Bather propose to use the prefix
Página 60 - The Terms of Auxology a1- justly criticised the nomenclature employed in my papers to designate the stages of growth and decline in the individual. They have also proposed in view of the correlations which have been shown to exist between the transformations that occur in the stages of development and decline in the individual and those that characterize the evolution of the group to which it may belong , to designate the study of these correlations by the new tenn »Auxology«.
Página 75 - Or, bringing the question to its ultimate and simplest form, we may say that as, on the one hand, physiological units will, because of their special polarities, build themselves into an organism of a special structure ; so, on the other hand, if the structure of this organism is modified by modified function, it will impress some corresponding modification on the structures and polarities of its units. The units and the aggregate must act and re-act on each other.
