Also, looking at the rocks in England, he can say which there were first-formed, second-formed, third-formed. He would, however, find it very difficult, if not impossible, to say which among any of the American rocks was formed at about the same time as any particular one among the English rocks, were it not for the help afforded him by these fossils.
Thus such of the first-formed strata as survived the repeated changes of level, would be practically "azoic;" like the Cambrian of our geologists. When by the washing away of the soft deposits, the hard sub-strata had been exposed in the shape of rocky islets, and a footing had thus been furnished, the pioneers of a new life might be expected to make their appearance. What would they be?
Turning, he found Benham beside him. "Good news, eh?" said that worthy. "Shake hands on it, Mr. Kilshaw." Kilshaw swallowed his first-formed words, and, after a moment's hesitation, put out his hand. Benham shook it warmly, saying, "I guess we'll blow him up between us. There's my fist on it. See you soon," and, with a lurching step and a leer over his shoulder, he walked on.
Although in the first instance the succession of fossils was understood by means of the succession of rock-layers, yet in the second place the arrangement of rock-layers is made more clear by the means of these very fossils. A geologist, looking at the rocks in America, can say which there were first-formed, which second-formed, which third-formed.
The reduced size of two of the toes as well as their lessened sensitiveness, seem to indicate a tendency to abortion; and on one of my plants the first-formed tendrils were sometimes simple, that is, were not divided into three toes. We are thus naturally led to the three following species with undivided tendrils Bignonia speciosa.
It resembles Kauai in that it is the first-formed and therefore the oldest island, so that it had had time sufficient to break down its lava rock into the richest soil, and to erode the canyons between the ancient craters until they are like Grand Canyons of the Colorado, with numberless waterfalls plunging thousands of feet in the sheer or dissipating into veils of vapour, and evanescing in mid-air to descend softly and invisibly through a mirage of rainbows, like so much dew or gentle shower, upon the abyss-floors.
The turning of the hand with the palm downwards. Pronator. The group of muscles which turn the hand palm downwards. A general term for the albuminoid constitutents of the body. A first-formed organized substance; primitive organic cell matter. Wing-like. One of a class of animal bases or alkaloids formed in the putrefaction of various kinds of albuminous matter.
Whilst the plant is quite young, the first-formed leaves are not modified in any way, but those next formed have their terminal leaflets reduced in size, and soon all the leaves assume the structure represented in the following drawing. This leaf bore nine leaflets; the lower ones being much subdivided.
