MARCH. 



The regular meeting of the Academy for March was held in 

 Symphony Hall on Monday, February 28, 1910, a large audience being 

 present. 



The speaker of the evening was Professor G. W. Ritchey, of the 

 Mount Wilson Solar Observatory. His subject was "Celestial Pho- 

 tography with Refracting ami Reflecting Telescopes." 



He gave a most interesting description of refracting and reflect- 

 ing telescopes, and the process of celestial photography, demonstrating 

 the great advantages of the reflector over the refractor in this work. 

 The types of refracting telescopes include the portrait Jens or 

 photographic-doublet; the standard photographic refractors with double 

 tubes, used in making the ' ' < 'aste du Oiel; " the great double refractors 

 of Potsdam and Meudon; the 36--inch Lick refractor and its photographic 

 corrector, and the 40-inch Yerkes refractor and its photographic 

 attachment. 



The reflecting telescopes described include the 24-ineh Yerkes 

 reflector; the 60-inch Mount Wilson reflector and the 100-inch Hooker 

 reflector now in process of manufacture. 



Sixty most beautiful photographs were thrown upon the screen 

 illustrating the results secured by the various types of telescopes. 

 These included views of the milky way, comets, star-clusters, nebulae, 

 and the moon. Those taken with the great 60-inch reflector were 

 most sharp in their definition and presented minute details of comets 

 and the moon, and particulars regarding the nebulae heretofore unknown. 



At the (dose of the lecture, a large portion of the audience remained 

 ami entered into an animated discussion with Professor Ritchey relat- 

 ing to his observations and the practical work in the manufacture of 

 astronomical instruments.
