above work is eminently suitable to meet such a demand, for it is a series of six 

 lectures adapted to a juvenile auditory, delivered at the Royal Institution at 

 Christmas 191 3, and treating the subject of astronomy in an easy style adequately 

 illustrated. The author has successfully accomplished the difficult task of bringing 

 an abstruse subject down to the comprehension of the juvenile reader, at the same 

 time making it attractive by the introduction of little anecdotes connected with 

 the well-known astronomers. The titles of the lectures, which of themselves 

 describe their contents, are as follows : The Starting Point, Our Earth, The 

 Length of our Voyage and the Start through the Air, Journeying by Telescope, 

 Visits to the Moon and Planets, Visit to the Sun, and Visits to the Stars.
