The internodes are smooth, the rootlets being attached at the nodes. The rootlets are filiform, and darker in color. The rhizome is covered by an epidermis, composed of muriform cells of a bright yellow color, after having been treated with liquor potassae to clear up the tissues.
I was speaking of those at Beauvais as suggesting the beech and the reed; if you think of the columns at Laon, they have nodes all up their stems, resembling the regular swelling of bamboos, to the point of imitation. Here the animal kingdom seems to have inspired the architect.
It is characterized by upright ears, a high bulbous snout and a grinning mouth. The teeth in some cases resemble the fangs of a serpent. The eyes consist of rounded nodes; and often curved lines, incised or in relief, extend from them or the mouth down the sides of the neck. The tail at the opposite end of the vessel is turned upward and coiled.
He was conscious of being irritated by ridiculously small causes, which were half of his own creation. Why was he making any fuss about Mrs. Casaubon? And yet he felt as if something had happened to him with regard to her. There are characters which are continually creating collisions and nodes for themselves in dramas which nobody is prepared to act with them.
Its window opened on to a balcony which, supported on thick oak balks, stood over the causeway of the street; its door was in a passage leading from one wing of the house to the other, and in the passage were three leaded lattice-windows of greenish glass, plentifully sprinkled with blobs and nodes, giving on the long inn-yard.
On the occurrence of a similar discord, the astronomer Lemonnier, of the Academy of Sciences, said one day to Lalande, his fellow-academician and former pupil, "I enjoin you not to put your foot again within my door during the semi-revolution of the lunar orbital nodes." Calculation shows this to be nine years.
The English Ivy, as we have seen, is also climbing, by means of its aërial roots. The Red Clover is ascending, the branches rising obliquely from the base. Some kinds of Clover, as the White Clover, are creeping, that is, with prostrate branches rooting at the nodes and forming new plants. Such rooting branches are called stolons, or when the stem runs underground, suckers.
This medullated sheath is interrupted at the nodes of Ranvier, and in each internode is a nucleus lying between the myelin and the neurolemma. The axis cylinder is the essential conducting structure of the nerve, while the neurolemma and the myelin act as insulating agents.
This circumstance proves likewise, that if there be a gradual diminution of the obliquity of the ecliptic, it does not arise only from an alteration in the position of the earth's axis, but rather from some change in the plane of the ecliptic itself; because the stars, at the end of the period of the moon's nodes, appeared in the same places, with respect to the equator, as they ought to have done, if the earth's axis had retained the same inclination to an invariable plane."
He discovered, also, the inequality in the inclination of the moon's orbit, and in the motion of her nodes. Tycho's powers of observation were not equalled by his capacity for general views. It was, perhaps, owing more to his veneration for the Scriptures than to the vanity of giving his name to a new system that he rejected the Copernican hypothesis.
