The secondary formations are more broken; but, as Bronn has remarked, neither the appearance nor disappearance of their many now extinct species has been simultaneous in each separate formation.
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.
Thus, as it seems to me, the parallel, and, taken in a large sense, simultaneous, succession of the same forms of life throughout the world, accords well with the principle of new species having been formed by dominant species spreading widely and varying; the new species thus produced being themselves dominant owing to inheritance, and to having already had some advantage over their parents or over other species; these again spreading, varying, and producing new species.
This was what I meant when I spoke of impressions which invited the intellect, or the reverse--those which are simultaneous
with opposite impressions, invite thought; those which are not simultaneous
All simultaneously generated engrams are associated; there is also association of successively aroused engrams, though this is reducible to simultaneous association.
The first, or "Law of Engraphy," is as follows: "All simultaneous excitements in an organism form a connected simultaneous excitement-complex, which as such works engraphically, i.
I'm going to hurry,' said Claire, clenching her fists as two simultaneous
bursts of song, in different keys and varying tempos, proceeded from the dining-room and kitchen.
For a moment, the whole party stood in suspense, awaiting the result, and then a simultaneous
impulse caused the whole to let off their pieces at the same instant, producing a noise which might not fail to reach the ears of all within so short a distance.
If we was to bind him to any other trade to-morrow, he'd run away simultaneous
, your worship,' replied Bumble.
And how much more interesting did the spectacle become, when, starting into full life and animation, as a simultaneous
call for 'Pickwick' burst from his followers, that illustrious man slowly mounted into the Windsor chair, on which he had been previously seated, and addressed the club himself had founded.
The triggers had been wired together, so as to make the simultaneous
discharge more destructive.
