Síða 373 - Paraguay offers the most curious instance of this; for here neither cattle nor horses nor dogs have ever run wild, though they swarm southward and northward in a feral state; and Azara and Rengger have shown that this is caused by the greater number in Paraguay of a certain fly, which lays its eggs in the navels of these animals when first born.
Síða 377 - That which persists, unchanging in quantity, but ever changing in form, under these sensible appearances which the universe presents to us, transcends human knowledge and conception, is AN UNKNOWN AND UNKNOWABLE POWER, WHICH WE ARE OBLIGED TO RECOGNISE AS WITHOUT LIMIT IN SPACE, AND WITHOUT BEGINNING OR END IN TIME.
Síða 374 - Battle within battle must be continually recurring with varying success; and yet in the long-run the forces are so nicely balanced, that the face of nature remains for long periods of time uniform, though assuredly the merest trifle would give the victory to one organic being over another.
Síða 374 - Paraguay, the parasitic insects would probably increase; and this would lessen the number of the navel-frequenting flies — then cattle and horses would become feral, and this would certainly greatly alter (as indeed I have observed in parts of South America) the vegetation: this again would largely affect the insects; and this, as we have just seen in Staffordshire, the insectivorous birds, and so onwards in ever-increasing circles of complexity.
Síða 377 - All these phenomena, from their great features down to their minutest details, are necessary results of the persistence of force, under its forms of matter and motion. Given these as distributed through space, and their quantities being unchangeable, either by increase or decrease, there inevitably result the continuous redistributions distinguishable as evolution and dissolution, as well as all those special traits above enumerated.
Síða 207 - And God sent an angel unto Jerusalem to destroy it: and as he was destroying, the LORD beheld, and he repented him of the evil, and said to the angel that destroyed, It is enough, stay now thine hand.
Síða 348 - Both these clusters gave a continuous spectrum. I then examined the Great Nebula in the Sword-handle of Orion. The results of telescopic observation on this nebula f seem to show that it is suitable for observation as a crucial test of the correctness of the usually received opinion that the resolution of a nebula into bright stellar points is a certain and trustworthy indication that the nebula consists of discrete stars after the order of those which are bright to us.
Síða 238 - The announcement of the comet of 1832 may produce similar effects, unless the authority of the Academy apply a prompt remedy ; and this salutary intervention is at this moment implored by many benevolent persons.
Síða 81 - it would be difficult to assign a limit to a gaseous atmosphere in space; and further, some writers, among whom I will here mention only Grove, Humboldt, Zollner, and Mattieu Williams, have boldly asserted the existence of a space filled with matter, and Newton himself, as Dr. Sterry Hunt tells us, has expressed views in favour of such an assumption.
Síða 345 - I think, I may safely say, that there can be little, if any doubt as to the resolvability of the Nebula.
