Paris to Egypt and Sidon (whereas the Cyclic poem called the Cypria ignored them), and also because the part of the Iliad from which it comes is cited as the " Aristeia of Diomede."
An examination of these arguments throws light on two chief aspects of the relation between Homer and his " cyclic " successors.
This conclusion he then supports by the character attributed to the " Cyclic " poems (whose want of unity showed that the structure of the Iliad and Odyssey must be the work of a later time), by one or two indications of imperfect connexion, and by the doubts of ancient critics as to the genuineness of certain parts.
Wolf had argued that if the cyclic writers had known the Iliad and Odyssey which we possess, they would have imitated the unity of structure which distinguishes these two poems. The result of Welcker's labours was to show that the Homeric poems had influenced both the form and the substance of epic poetry.
The tendency to amplify and complete the story shows itself still more in the Cyclic poets.
Noticed above between the Iliad and the Odyssey, and between Homer and the early Cyclic poems. And the peculiar degradation of Homeric characters which appears in some poets (especially Euripides) finds a parallel in the later chansons de geste.3 The comparison of Homer with the great literary epics calls for more discursive treatment than would be in place here.
Although originally described as acetylketen, it has proved to be a cyclic compound (Ber., 1909, 4 2, p. 4908).
With the fall of water there is an increase in the specific gravity, which in 1850 was 1.17, and in September 1901 was I 179; in 1850 the proportion of solids by weight was 22.282%, in September 1901 it was 25.221; at the earlier of these dates the solids in a litre of water weighed 260.69 grams, at the latter date 302'122 grams. The exact cause of this cyclic variation is unknown: the low level of 1906 is usually regarded as the result of extensive irrigation and ploughing in the surrounding country, which have robbed the lake, in part, of its normal supply of water.
Pyrocatechin readily condenses to form heterocyclic compounds; cyclic esters are formed by phosphorus trichloride and oxychloride, carbonyl chloride, sulphuryl chloride, &c.; whilst ortho-phenylenediamine, o-aminophenol, and o-aminothiophenol give phenazine, phenoxazine and thiodiphenylamine.
POLYMETHYLENES, in chemistry, cyclic compounds, the simplest members of which are saturated hydrocarbons of general formula C 7, H 2nj where n may be r to 9, and known as tri-, tetra-, penta-, hexa-, and hepta-methylene, &c., or cyclo- propane, -butane, -pentane, -hexane, -heptane, &c.: - CH 21 CH 2 CH 2 CH2.CH2 CH2 CH2 CH2?C1H,, I I H ?
Senderens, loc. cit.); by the reduction of cyclic esters with CH 2 CH2 / NCH2- -CHI sodium and alcohol (L.
Blanc, Comptes rendus, 1903, 136, p. 1676; 137, p. 60); and by the addition of the elements of water to the unsaturated cyclic hydrocarbons on boiling with dilute acids.
When a flower consists of parts arranged in whorls it is said to be cyclic, and if all the whorls have an equal number of parts and are alternate it is eucyclic (figs.
In Symmetry contrast to the cyclic flowers are those, as in Magnoli of the flower.
If the fluctuations are irregular and non-periodic, teristics the sound is called a noise; if they are cyclic and follow a regular and sufficiently rapid periodic law, the sound is musical.
Deferring the detailed discussion of cyclic or ringed hydrocarbons, a correlation of the various types or classes of compounds which may be derived from hydrocarbon nuclei will now be given.
It will be seen that each type depends upon a specific radical or atom, and the copulation of this character with any hydrocarbon radical (open or cyclic) gives origin to a compound of the same class.
It may be noticed here that cyclic nuclei can only contain the groups > CH 2.
Cyclic Hydrocarbons and Nuclei.
Zincke; and his researches have led to the discovery of many chlorinated oxidation products which admit of decomposition into cyclic compounds containing fewer
