Page 698 - If I was right in calculating that the present delta of the Mississippi has required, as a minimum of time, more than one hundred thousand years for its growth,* it would follow, if the claims of the Natchez man to have coexisted with the mastodon are admitted, that North America was peopled more than a thousand centuries ago by the human race. But even were that true, we could not presume, reasoning from ascertained geological data, that the Natchez bone was anterior in data to the antique flint...
Page 168 - They prove that while the reproductive cells multiply and arrange themselves during the evolution of the embryo, some of their germ-plasm passes into the mass of somatic cells constituting the parental body, and becomes a permanent component of it.
Page 166 - Now, what happens when one puts such mixed-blood ewes to a pure New-Kent ram ? One obtains a lamb containing fifty hundredths of the purest and most ancient English blood, with twelve and a half hundredths of four different French races, which are individually lost in the preponderance of English blood, and disappear almost entirely, leaving the improving type in the ascendant.

Page 485 - ... must take it as a demonstrated fact that, during gestation, traits of constitution inherited from the father produce effects upon the constitution of the mother ; and that these communicated effects are transmitted by her to subsequent offspring. We are supplied with an absolute disproof of Professor Weismann's doctrine that the reproductive cells are independent of, and uninfluenced by, the somatic cells ; and there disappears absolutely the alleged obstacle to the transmission of acquired characters.
Page 461 - ... discussion which occurred at the British Association Meeting in 1888, so far as our judgment goes, simply proved that the decisions of the conference could not at present be disregarded. As the president of the meeting, Sir William...
Page 697 - It appeared to be quite in the same state of preservation, and was of the same black color, as the other fossils, and was believed to • have come, like them, from a depth of about thirty feet from the surface. In my
Page 414 - DISCOURSE was deemed man's noblest attribute, And written words the glory of his hand ; Then followed printing with enlarged command For thought, dominion vast and absolute For spreading truth, and making love expand. Now prose and verse sunk into disrepute Must lacquey a dumb art that best can suit The taste of this once-intellectual land. A backward movement surely have we here, From manhood, back to childhood ; for the age — Back towards caverned life's first rude career. Avaunt this vile abuse...
