Agonic

There are two lines on the earth's surface which have been called agonic lines, upon which there is no declination; and where, therefore, the needle is directed along the terrestrial meridian.

It is contended by some that their [cyclones'] general movement is at right angles to the magnetic meridian. If this should prove to be correct, then in all that part of the United States lying west of the Agonic Line, the general direction whence local rain, hail, and snow-storms come, will be as many degrees north of west as the declination of the needle is east of north; and in all that part of the territory lying east of said Agonic Line, they will come from a direction as many degrees south of west as the declination of the needle is west of north.

One of these [agonic lines] passes over the American and the other over the Asiatic continent, and the former has consequently been called the American and the latter the Asiatic agonic. […] On the west of the Asiatic agonic the declination is west, on the east it is east.

It should be noted that the period of 2000 years deduced from the average motion of the agonics is identical with that which we obtain if we suppose that the secondary magnetic system revolves around the equator at the average rate of the two secondary poles, viz: ³⁶⁰⁄_(0.194) = 1860 years.

By cultivating his own reason, the pupil could stand back from the agonic scenes in Hades and decide the merits of the case after [François] Fénelon's artifice had absorbed him passionately in the dialogue: […]

Thus, the opening citation, the eleventh section of The Case of Wagner, the passage which perhaps is the zenith of [Friedrich] Nietzsche's irony, is succeeded by the brief agonic cry of the twelfth section: […]

Eagerly following the convention of crick-crack stories, his audience, entranced by Solibo's words and the rhythmic sound of the gwo-ka, duly responds Patat'si to Solibo's agonic cry.

[I]n some primates, especially chimpanzees, the hedonic mode of social communication predominates group interactions. […] This is marked by much physical contact, stroking, hugging, lip smacking and sharing. The social interactions are more relaxed, as are the individual members of the group, and there is much focus on physical contact. This is in marked contrast to other more primitive primates, where the agonic mode dominates social behaviour.
