Description:Excerpt from Proceedings of the American Association for the Advancement of Science: Third Meeting, Held at Philadelphia, Penn, September, 1884 Then there is the very interesting discussion concerning changes upon the moon's surface. Considering the difference between our modern telescopes and those employed fifty or a hundred years ago, I think it still far from certain that the differences between the representations of earlier and later observers necessarily imply any real alterations. But they, no doubt, render it considerably probable that such alterations have occurred, and are still in prog ress, and they justify a persistent, careful, minute, and thorough study of the details of the lunar surface with powerful instruments especially do they inculcate the value of large-scale photographs, which can be preserved for future comparison as unimpeachable witnesses. I will not leave the moon without a word in respect to the re markable speculations of Professor George Darwin concerning the tidal evolution of our satellite. Without necessarily admitting all the numerical results as to her age and her past and future history, one may certainly say that he has given a most plausible and satis factory explanation of the manner in which the present state of things might have come about through the operation of causes known and recognized, has opened a new field of research, and shown the way to new dominions. The introduction of the doc trine of the conservation of energy, as a means of establishing the conditions of motion and configuration in an astronomical system, is a very important step. In the planetary system we meet, in the main, the same prob lems as those that relate to the moon, with a few cases of special interest.
