Page 48 - At the end of the fifteenth and the beginning of the sixteenth century, society was in a state of excitement.
Page 194 - There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.
Page 206 - Those who survey the work done in this department will arrive at the conviction that among all the numerous experiments made, not one has been carried out to such an extent and in such a way as to make it possible to determine the number of different forms under which the offspring of hybrids appear, or to arrange these forms with certainty according to their separate generations, or definitely to ascertain their statistical relations*.
Page 168 - They continue this day as they were created, perfect in number and measure and weight ; and from the ineffaceable characters impressed on them we may learn that those aspirations after accuracy in measurement...
Page 212 - ... cultivation of the seeds produced, be again shown to be made up of pure dominants and cross-breds in the same proportion of one dominant to two cross-breds. " The process of breaking up into the parent forms is thus continued in each successive generation, the same numerical law being followed so far as has yet been observed. Mendel made further experiments with...
Page 78 - Payne has pointed out his importance as a forerunner of Harvey. He made Greek methods available; through him the art of Hippocrates and the science of Galen became once more the subject of careful, first-hand study. Linacre, as Dr. Payne remarks, "was possessed from his youth till his death by the enthusiasm of learning. He was an idealist, devoted to objects which the world thought of little use.
Page 215 - ... combination forms, and that these egg and pollen cells agree in their internal composition with those of the separate forms. In point of fact it is possible to demonstrate theoretically that this hypothesis would fully suffice to account for the development of the hybrids in the separate generations, if we might at the same time assume that the various kinds of egg and pollen cells were formed in the hybrids on the average in equal numbers.
Page 99 - ... a great multitude of ignorant persons, of whom the greater part have no manner of insight in the same, nor in any other kind of learning ; some also can read no letters on the book, so far forth that common artificers, as smiths, weavers, and women...
Page 215 - ... plants. Since the various constant forms are produced in one plant, or even in one flower of a plant, the conclusion appears logical that in the ovaries of the hybrids there are formed as many sorts of egg cells, and in the anthers as many sorts of pollen cells, as there are possible constant combination forms, and that these egg and pollen cells agree in their internal composition with those of the separate forms.
Page 208 - It requires indeed some courage to undertake a labour of such farreaching extent; this appears, however, to be the only right way by which we can finally reach the solution of a question the importance of which cannot be overestimated in connection with the history of the evolution of organic forms. The paper now presented records the results of such a detailed experiment. This experiment was practically confined to a small plant group, and is now, after eight years' pursuit, concluded in all essentials.
