By Mr. cAlex, Laing, Detroit, Mich, 



Aprii, io, 1906. 



Synopsis 



This lecture was very interesting, being illustrated by Laing's 

 Planetarium, an instrument of the lecturer's own invention and 

 construction. Mr. lyaing very clearly showed the motions of the 

 planets, comets, asteroids, etc., around the sun, explaining to the 

 uninitiated the relation of time and longitude, the ecliptic (equin- 

 oxes) and solstices, the various eclipses, nodes, tides, seasons, 

 right ascension and declination. 



The lecture was ver}' heartily appreciated and a vote of thanks 

 tendered the lecturer. 



The Heavens Declare the Glory of God 



By Rev, D, B. Marsh, ScD,, F,R,A,S, 



Sy?iopsis 



In this the lecturer dealt largely with the immensity, variety, 

 and numbers of the heavenly bodies; with their marvellous vel- 

 ocity and accuracy of the laws governing them. From this he 

 sought to show the greatness of Him who created and sustains 

 them.
