“ Martin referring to Procyon writes: "It is in fact a most beautiful star, and is only the sixth in order of brightness among the stars seen in our latitude. It is very distinctly individual, being the only one among the beautiful winter group that is lightly tinged with yellow. It is one of the Sirian class of stars, but is somewhat further developed than Sirius, and is beginning to have the golden tint which signifies that it is approaching the time of life into which Capella and the sun are well passed." ”
