This little group of stars is of course the same as the one on #19, but seen
from ten times farther away. We could give for all of them the names by
which the astronomers know them, but we mention only 12 of the best known,
putting numbers under the corresponding stars in #19, as there is room for them
there. First the sun (1); then Alpha Centauri (2), Beta Hydri (3), Delta Pavloni
(4), Castor (5), Pollux (6), Capella (7), Procyon (8), Sirius (9), Arcturus (10),
Altair (1 1) and Vega (12). No attempt has been made to indicate the relative
brightness of the stars shown, for it would be very different as seen from our
present faraway point of observation from what it appears to be from the earth.
