The young cell-wall is always tenuous and flexible, and may remain so throughout, but in many cases thickenings and structural differentiations, as well as the changes referred to above, alter the primary wall considerably.
In other words, the light may be an exceedingly tenuous cometary tail to the earth, visible only because seen through its very great length.
Newton he entertained a confident belief in Providence, founded not on any tenuous inference, but on personal feeling.
Let the old man think of something—after all, he'd been the one to make the Scranton connection, however tenuous, in the first place.
The hypothesis which best explains all the phenomena is that the light is that of the sun reflected from an extremely tenuous cloud of particles having the form and extent described, and becoming more and more tenuous as the earth's orbit is approached until, immediately outside the orbit, it fades into complete invisibility.
Since the tenuous edge of the lens extends beyond the earth's orbit it follows that there must be some zodiacal light, whether it can be seen or not, passing entirely across the sky, along or near the ecliptic. Observations of this zodiacal band are therefore of great interest.
It seems not unlikely that the final conclusion will be that instead of the reflecting matter being composed of solid particles it is an exceedingly tenuous gaseous envelope surrounding the sun and revolving on an axis the mean position of which is between that of the sun's equator and that of the invariable plane of the solar system.
If he tried to follow a moving automobile, he could sometimes attach himself, if the vehicle was slow or stopped, but the act was tenuous at best.
His sole venture at the end of a rope was the prior winter in Ouray's ice climbing park, under even more tenuous circumstances.
