It was as if the three mourned together over the remains of some dear one who lay dead among them. Hartley bowed low, with an uncontrollable shiver, and turned to the tea-table, where Miss Benham sat in the seat of authority, flanked by a young American lady whom he had met before, and by Baron de Vries, whom he had not seen since the evening of the De Saulnes' dinner-party.
A new generation of evolutionists has within the past twenty years arisen which holds that the changes in the organizations of plants and animals do not come by slow growth of favorable characteristics, but arise suddenly. Such is the "Mutation" theory of Hugo de Vries.
Baron de Vries paused as if he did not mean to finish his sentence, and Hartley said: "You say 'afraid'! Why afraid?" The Belgian looked up at him reflectively. "Did I say 'afraid'?" he asked. "Well, perhaps it was the word I wanted. I wonder if these two are fitted for each other. I am fond of them both. I think you know that, but she's not very flexible, this child. And she hasn't much humor.
She knew Baron de Vries well, and she knew that it was not his habit to show or to feel a strong liking for young and idle men. This young man must be very worth while to have won the regard of that wise old Belgian.
"Vries verified this rapid transformation first in a plant named OEnotheria Lamarckiana, which, all of a sudden, with no influence from the environment, with nothing to justify it, at times changes and metamorphosizes itself into a different plant." "But this transformation may be due to a disease," said Alzugaray.
No wonder, therefore, that Napoleon III so Vries said had his portrait in an album containing, besides, only portraits of European sovereigns. He pretended that he had made many important prophecies. This was a bond between him and Hello, who claimed the same extraordinary power, and had foretold all sorts of singular events.
The first-named law was propounded by Gregor Mendel on the basis of extensive experiments upon plants conducted during many years, 1860 and later, in the obscurity of his monastery garden at Altbrünn, in Austria. It was rescued from oblivion by De Vries, who found it buried in a mass of literature and brought it to light when he published his renowned Mutation Theory in 1901.
Many instances have been suggested in which the theory of gradual changes could not explain the facts. The theory of mutation, of which Hugo de Vries, of Holland, is the chief expounder, does not antagonize Darwin, but simply gives more weight in the process of evolution to the factor of sudden changes commonly called sports.
In a subsequent passage Sachs seems to feel some difficulty in accounting for this kind of contraction. It must not however be supposed from the foregoing remarks that I entertain any doubt, after reading De Vries' observations, about the outer and stretched surfaces of attached tendrils afterwards increasing in length by growth.
De Vries said of the climate "that during the months of June, July and August it was very unhealthy, that then people that had lately arrived from England, die, during these months, like cats and dogs, whence they call it the sickly season." So likely was it that a newcomer would be stricken down that a "seasoned" servant was far more desirable than a fresh arrival.
