Strona 50 - ... the original normal posture, the other (het. dv.) when it is placed upside down on the opposite side of the body. These combinations may be termed harmonic. The other two combinations, the simply inverted bud (horn, dv.) and the bud planted on the opposite side of the body in upright position (het. dd.), result primarily in limbs that are not normally placed in relation to the cardinal points of the embryo, and may be termed disharmonic. In comparing the distribution of single and reduplicated...
Strona 5 - Accordingly, with the aid of a grant from the Bache Fund of 'the National Academy of Sciences, the investigation was begun in 1911.
Strona 45 - November 14, 1916 The specificity of the tissue of the limb bud in the amphibian embryo has been clearly shown by Braus,1 who found that when transplanted to any part of the body it would develop into a normal appendage. Since then evidence has accumulated2 to show that the limb rudiment, and more especially its mesoderm, constitutes an equipotential system.
Strona 58 - A second point of importance is that the 'rhythms' in the division rate are to a certain extent independent of endomixis — that is of the definitive series of nuclear phenomena — because the rhythms persist for a while in the absence of the morphological changes. One may suggest that the rhythms in the culture are an expression of the physiological conditions antecedent to the definitive onset of the nuclear changes — in other...
Strona 49 - ... result. The three limbs then have approximately the same relations as found by Bateson,10 especially in arthropods. In two of the combinations the limbs that develop are in normal orientation with respect to the cardinal points of the embryo. One of these (horn, dd.) is when the graft is placed in the original normal posture, the other (het. dv.) when it is placed upside down on the opposite side of the body. These combinations may be termed harmonic. The other two combinations, the simply inverted...
