They afforded besides a particularly well-marked example of that diffuseness of radiation previously observed in some less conspicuous displays. Their paths seemed to diverge from an area rather than from a point in the sky. They came so ill to focus that divergences of several degrees were found between the most authentically determined radiants.
A great angel, attended by a company of shining ones, came down to meet and receive them, but merrily evading them all, up still they ran. In merry dance, however, a group of woman-angels descended upon them, and in a moment they were fettered in heavenly arms. The radiants carried them away, and I saw them no more.
Their seeming swiftness is very various, and what is highly significant it is notably less when they pursue than when they meet the earth. Yet the "incredible and unaccountable" fact of the existence of these "long radiants," although doubted by Tisserand because of its theoretical refractoriness, must apparently be admitted.
In other words, the application of the proper correction for the terrestrial movement, and the effects of attraction by which each individual shooting-star is compelled to describe a hyperbola round the earth's centre, reduces the extended line of radiants to a compact group, with the cometary radiant for its central point; the cometary radiant being the spot in the sky met by a tangent to the orbit of the Perseid comet of 1862 at its intersection with the orbit of the earth.
Kleiber showed, by strict geometrical reasoning, that the forty-nine radiants successively determined for the shower were all, in fact, comprised within one narrowly limited region of space.
Denning during ten years' patient watching of such phenomena at Bristol. These are described as "meteors with stationary radiants," since for months together they seem to come from the same fixed points in the sky. Now this implies quite a portentous velocity. The direction of meteor-radiants is affected by a kind of aberration, analogous to the aberration of light.
Her frank curiosity showed so plainly in her face that the fine wrinkles about the young man's eyes became little radiants of amusement centering around gray pupils and his lips parted in a smile over very even teeth.
The one nearest to the glass suddenly unfolded itself with the violence of a spring escaping from an explosive projectile. He gave a bound, remaining fastened to the ground by one of his radiants, and raised the others like a bundle of reptiles.
Yet, since a few detonating meteors have been found to proceed from ascertained radiants of shooting-stars, it is difficult to suppose that any generic difference separates them. Their assimilation is further urged though not with any demonstrative force by two instances, the only two on record, of the tangible descent of an aerolite during the progress of a star-shower.
