The equipment of school furniture, such as seats, desks, dictionaries, text books, globes and outline maps; drawing-boards, blackboards and laboratory outfit; glass cases, for collections of geological specimens and minerals; life size, physiology models and charts; together, with a complete series of charts for the other sciences; is the best that could be designed or procured.
The city is piled up in strata like a geological deposit. What lies hidden at the bottom is scarcely known at all; that is from the time of the early kings of Rome.
The break in the supposed chain of evolution between the invertebrates and the highly organized vertebrates of the Lower Silurian is one of the greatest in the whole geological record. The vast gulf between these structures must, I think, remain unbridged except by the imagination." The late Prof.
The rise of the land had connected many hitherto isolated regions, and they seem to have poured over every bridge into all parts of the four continents. The obscurity of their origin is richly compensated by their intense evolutionary interest from the moment they enter the geological record.
These principles come into play only by bringing organisms into new relations with each other, and in a lesser degree with the surrounding physical conditions. As we have seen in the last chapter that some forms have retained nearly the same character from an enormously remote geological period, so certain species have migrated over vast spaces, and have not become greatly modified.
Hence it will be worth while to sum up the foregoing remarks, under an imaginary illustration. The Malay Archipelago is of about the size of Europe from the North Cape to the Mediterranean, and from Britain to Russia; and therefore equals all the geological formations which have been examined with any accuracy, excepting those of the United States of America. I fully agree with Mr.
John W. Webster was at this time Professor of Chemistry and Mineralogy in Harvard University, a Doctor of Medicine and a Member of the American Academy of Arts and Sciences, the London Geological Society and the St. Petersburg Mineralogical Society. He was the author of several works on geology and chemistry, a man now close on sixty years of age.
Nevertheless, looking to a remotely future epoch, there can, I think, be little doubt that all the more modern marine formations, namely, the upper pliocene, the pleistocene and strictly modern beds, of Europe, North and South America, and Australia, from containing fossil remains in some degree allied, and from not including those forms which are only found in the older underlying deposits, would be correctly ranked as simultaneous in a geological sense.
The next time you come you will have to behave yourself, and to stay till Somebody has had enough of you. Mabel thinks I ought to enliven the account of my trip with descriptions of scenery and the like. But a rock is a rock, and a field is a field, and who wants to know whether a tree is elm or maple? I am not a geological survey, and you can get mountains enough from Craddock.
But in a moment or two Powell and Hillers, who had both been pulled down by the whirlpool that was keeping all together, shot up like rockets beside me, and then I noticed Jones clinging to the ring in the stern. As we told Powell, after this experience was over, he had tried to make a geological investigation of the bed of the river, and this was not advisable.
