 ... 1905) states that there is always obliteration of the anterior scleral venous channels (Schlemm's canal) in buphthalmos. Seefelder (Graefe's Arch. V. 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 (Ann. d'Oculis CXLVII) suggests that injury to mesoderm ...

... Louis. Then there are the three cases of crossing: by conjugation, Ursule, Aristide, Anna, Victor; by dissemination, Maxime, Serge, Etienne; by fusion, Antoine, Eugene, Claude. I even noted a fourth case, a very remarkable one, an even cross, Pierre and Pauline; and varieties are established, the differentiation of the mother, for example, often accords with the physical resemblance of the father; or, it is the contrary which takes place, so that, in the crossing, the physical and mental predominance remains with one parent or the other, according to circumstances. Then here is indirect heredity, that ...

... infused into this analysis with the division of relatively undifferentiated muscles into subordinate groups. The differentiation of the muscles was related to changing food habits, increased mobility of the head, and increase in the freedom of movement of the shoulder girdle and forelimbs (Olson, 1961:214). As Olson has pointed out, this further localized the stresses to which the bone was subjected. Additional localization ...

... century B.C., as if the double office were already a Celtic institution.[525] Mythic Celtic kings consulted the gods without any priestly intervention, and Queen Boudicca had priestly functions.[526] Without giving these hints undue emphasis, we may suppose that the differentiation of the two offices would not be simultaneous over the Celtic area. But when it did take effect priests would probably lay claim to the prerogatives of the priest-king as incarnate god. Kings were not likely to give these up, and where they retained them ...

They are capable of using the outward and apparent motives of humanity for an effect, and secretly of plying ...

... channel a child retains most words. Then, in dealing with that child, make your appeals predominantly through that channel. If the class were very small, results of some distinctness might doubtless thus be obtained by a painstaking teacher. But it is obvious that in the usual schoolroom no such differentiation of appeal is possible; and the only really useful practical lesson that emerges from this analytic psychology in the conduct of large schools is the lesson already reached in a purely empirical way, that the teacher ought always to impress the class through ...

... powers of languages seem to have ceased when they were on the eve of completion: they became fixed or crystallized in an imperfect form either from the influence of writing and literature, or because no further differentiation of them was required for the intelligibility of language.

... There is no precise date at which we take up each of the successive stories, but the main sweep of development has to do in each case with the nineteenth century. We shall see at once that this is a time both of rapid progress and of great differentiation.

Meantime, astronomy and what the workers of the elder day called natural philosophy become ...

For all the twenty-odd years between them, and the gulf of sex differentiation, there was in her glance and bearing much of the middle-aged man who sat on the porch with a book across his knees and a clay pipe in his mouth. It did not lie in facial resemblance. It was more subtle than likeness of feature. Perhaps it was because of their eyes, alike deep gray, wide and ...

... argument is that nearly any one who gives his mind to it can achieve success. This is, to put it briefly, untrue. The very central idea of success is separation from the multitude of plain men; it is perhaps the only idea common to all the various sorts of success—differentiation from the crowd. To address the population at large, and tell it how to separate itself from itself, is merely silly. I am now, of course, using the word success in its ordinary sense. If human nature were more ...

Take a seed from the garden. What interest it has for us all lies in our sense of potential differentiation to come: the leaves, leaf upon leaf, the flowers, a thousand new seeds in turn. It is so with animal seed; and with humanity, individually, or as a whole, its expansion into a detailed, ever-changing, parti-coloured history ...

... though the cells that engender the sexual elements do not generally appear at the beginning of the embryonic life, it is none the less true that they are always formed out of those tissues of the embryo which have not undergone any particular functional differentiation, and whose cells are made of unmodified protoplasm.[8] In other words, the genetic power of the fertilized ovum weakens, the more it is spread over the growing mass of the tissues of the embryo; but, while it is being thus diluted, it is concentrating anew something of itself on a certain ...
