For all the species of the same group, however long it may have lasted, are the modified descendants one from the other, and all from a common progenitor. In the genus Lingula, for instance, the species which have successively appeared at all ages must have been connected by an unbroken series of generations, from the lowest Silurian stratum to the present day.
Now it was that we began to hang upon those readings in almost breathless anxiety. One hundred and fifty-three degrees had been the maximum temperature above the ice stratum. Would it stop at this point again, or would it continue its merciless climb? We knew that there was no hope, and yet with the persistence of life itself we continued to hope against practical certainty.
It often happens that the thickest and best layer is the lowest, and when this is the case, it is usually mined first, regardless of the fact that some, and possibly all, of the higher beds are dislocated and broken or filled with deadly gases. Nearly all this loss could be avoided by simply mining the upper stratum first. So much for waste at the mines.
Cassian beds exhibiting an abundant fauna of mixed mesozoic and palaeozoic types, in rocks of an epoch once supposed to be eminently poor in life; witness, lastly, the incessant disputes as to whether a given stratum shall be reckoned devonian or carboniferous, silurian or devonian, cambrian or silurian.
Harvard, and birth in a social stratum where emphasis is superfluous, enabled him to smile at the reporter's exuberance; and he was the more drawn toward her to see on Janet's flushed face the hint of a smile as she looked up at him when she had finished.
But the days of my childhood are gone; I am a man and have to fight the battles of men, so I shall limit myself to the few facts that are pertinent to the discussion before us. "In the past six months I have made the sudden transition from the highest stratum of society to the one in which I am to-day.
They thought of him as coming from that stratum of clay that could be molded into a rail-splitter and, when the need arose, remodeled into the nation's leader. And quickly and unexpectedly, Sergeant York was destined to show by two other deeds, prompted by an inborn eminence, that the esteem was not misplaced.
But their light, too, was dim, and veiled as it were with clouds. Soft music was heard from these artificial heavens, and in the stratum of air immediately beneath, the blare of war-trumpets and battle- cries were heard. Thus all eyes were directed upward, and Diodoros's with the rest.
Nevertheless, the positive and negative evidence all points the other way. The skeletons of the full-grown, deep-sea Globigerinae are so remarkably solid and heavy in proportion to their surface as to seem little fitted for floating; and, as a matter of fact, they are not to be found along with the Diatoms and Radiolaria, in the uppermost stratum of the open ocean.
No time is spent in "placing" them in a given stratum of society, or in establishing their heredity, traditions, education, and so forth. And, finally, the very copiousness of expression permitted by the rhetorical Elizabethan form came to Shakespeare's aid. The modern dramatist is hampered by all sorts of reticences. He has often to work rather in indirect suggestion than in direct expression.
