15 Text,  6 |            slower motions than other stars. Here again we have a definable
16 Text,  7 |         extend. How far away are the stars? One of the unities which
17 Text,  7 |              the conclusion that the stars must be at very different
18 Text,  7 |           based on the fact that the stars seem to be scattered equally
19 Text,  7 |              is with the universe of stars. If the latter are sown

23 Text,  8 |            sun, the direction of the stars must appear to be a little
24 Text,  8 |           called the parallax of the stars; and the problem of measuring

32 Text,  11|         estimate, that the number of stars we have supposed would be
33 Text,  12|        impossible that the number of stars is much greater than that

36 Text,  13|           speed at which many of the stars are moving to or from us
37 Text,  13|            made only on the brighter stars - becoming very difficult
38 Text,  13|             difficult in the case of stars not plainly visible to the
39 Text,  14|            with which the individual stars move in space; and that

44 Text,  14|             parallax only show eight stars within the sphere of this
45 Text,  14|             greater thickness of the stars. But, after all, the discrepancy

56 Text,  16|             it seems likely that the stars are distributed through
57 Text,  16|        estimate, that nearly all the stars which we can see with our
58 Text,  17|      question. Granting that all the stars we can see are contained

64 Text,  18|            of the fainter telescopic stars. In fact, it has long been
65 Text,  18|          infinite in extent, and the stars equally scattered through
