Two primary divisions of carbocyclic compounds may be conveniently made: (I) those in which the carbon atoms are completely saturated - these are known by the generic term polymethylenes, their general formula being (CH 2), t: it will be noticed that they are isomeric with ethylene and its homologues; they differ, however, from this series in not containing a double linkage, but have a ringed structure; and (2) those containing fewer hydrogen atoms than suffice to saturate the carbon valencies - these are known as the aromatic compounds proper, or as benzene compounds, from the predominant part which benzene plays in their constitution.
But it so happened, that those boats, without seeing Pip, suddenly spying whales close to them on one side, turned, and gave chase; and Stubb's boat was now so far away, and he and all his crew so intent upon his fish, that Pip's ringed horizon began to expand around him miserably.
In the addax (Addax nasomaculatus), which is a distinct species common to North Africa and Syria, the ringed horns form an open spiral ascending in the plane of the face, and there is long, shaggy, dark hair on the fore-quarters in winter.
They have heavily fringed necks and tufted tails; the bucks carry long sublyrate and heavily ringed horns, but the does are horn- - - less.
The Germans ringed him round, and, with their hands raised high in the fashion of a landsknecht who had struck a successful blow, passed out into the street and escorted him to his lodgings.
The sable and roan antelopes are distinguished from Oryx by the stout and thickly ringed horns rising vertically from a ridge over the eyes at an obtuse angle to the plane of the lower part of the face, and then sweeping backwards in a bold curve.
At the shoulder, and characterized by the presence of a bare glandular spot below the ear, the upright horns of the bucks, which are ringed for a short distance above the face, and the tufted bushy tail, of which the terminal two-thirds are black.
The ringed structure of benzene, C 6 H 61 was first suggested in 1865 by August Kekule, who represented the molecule by six CH groups placed at the six angles of a regular hexagon, the sides of which denoted the valencies saturated by adjacent carbon atoms, the fourth valencies of each carbon atom being represented as saturated along alternate sides.
A small family of large forms with a ringed and flattened body.
Natrix, the grass or ringed snake, is very common in Europe, including England but not Scotland or Ireland; easily recognized even at a distance by two yellow or white spots which it has behind its head.
