Page 15 - ... on the bottom. They must take much of their food near the surface, as the life of the depths is apparently very sparse. This habit is rendered easy by the structure of the fish, for the mouth is directed partly upwards, and the head is very flat above, thus allowing the mouth to be at the surface.
Page 59 - In a paper read before the Geological Section of the British Association, at the Plymouth meeting, last August, Mr.
Page 582 - Fifteen hundred annual layers have been counted, or satisfactorily made out, upon one or two fallen trunks. It is probable that close to the heart of some of the living trees may be found the circle that records the year of our Saviour's nativity. A few generations of such trees might carry the history a long way back. But the ground they stand upon, and the marks of very recent geological change and vicissitude in the region around, testify that not very many such generations can have flourished...
Page 368 - ... the Pipit from its back on to the edge. It then stood quite upright on its legs, which were straddled wide apart, with the claws firmly fixed half-way down the inside of the nest among the interlacing fibres of which the nest was woven, and, stretching its wings apart and backwards, it elbowed...
Page 84 - Our joy at being chosen for this expedition -roused our courage, and sweetened the labor of rowing from morning till night. As we were going to seek unknown countries, we took all possible precautions, that, if our enterprise was hazardous, it should not be foolhardy; for this reason we gathered all possible information from Indians who had frequented those parts, and even from their accounts traced a map of all the new country, marking down the rivers on which we were to sail, the names of the nations...
Page 84 - Information that we could from the savages who had frequented those regions; and we even traced out from their reports a Map of the whole of that New country; on it we indicated the rivers which we were to navigate, the names of the peoples and of the places through which we were to pass, the Course of the great River, and the direction we were to follow when we reached it.
Page 414 - Arachnidans were observed, one a true spider, the other related to the "long-legs" of the woods. A species, similar to the former, is found in the Mammoth Cave, and others in other caves, but in every instance where I have obtained them, they have been lost by the dissolution of their delicate tissues in the impure alcohol. The other forms are more completely chitinized and are easily preserved.
Page 578 - I have been to a great extent a closet botanist Until this summer I had not seen the Mississippi, nor set foot upon a prairie. To gratify a natural interest, and to gain some title for addressing a body of practical naturalists and explorers, I have made a pilgrimage across the continent. I have sought and viewed in their native haunts many a plant and flower which, for me, had long bloomed unseen, or only in the hortus siccus. I have been able to see for myself what species and what forms constitute...
Page 595 - ... before them, and that they were as well adapted to their surroundings then, as those which flourish and bloom around u< are to their conditions now. Order and exquisite adaptation did not wait for man's coming, nor were they ever stereotyped. Organic nature — by which I mean the system and totality of living things, and their adaptation to each other and to the world — with all its apparent and indeed real stability, should be likened, not to the ocean, which varies only by tidal oscillations...
Page 95 - The abundant rams which had fallen during this season had swelled our little rivers, and freed us from the currents which we feared. At last we perceived our own agreeable country, the wild buffaloes and herds of stags wandering on the borders of the river...
