The first stars which I learnt from the celestial globe were alpha Lyrae, alpha Aquilae, alpha Cygni: and to this time I involuntarily regard these stars as the birth-stars of my astronomical knowledge.

Mr Stone's results for the radiation from Arcturus and alpha Lyrae appear to be incontrovertible, and to give bases for distinct numerical estimation of the radiant heat of these stars.
