In the library are two astronomical precision clocks made by 

 Riefler and Munich. These are the finest clocks ever made, their 

 record surpassing- in exactness all other clocks. These clocks 

 do not require winding as does an ordinary clock, for they are 

 provided with a series of magnets, which by electric contact 

 wind them every 84 or 38 seconds. A third clock is provided for 

 the transit room, which is of the standard type made by the Seth 

 Thomas Clock Company. 



Fiti. -t. John Alfred IJrashoiir, Director of the Allegheny Observatory, who 

 gave an adclr(>ss on Resolutions of the Telescope at the dedication of the Swasey 

 Observatory. 



The address of Doctor Brashear was a very illuminating and in- 

 teresting discussion of the universe and the means of studying it, a 

 sketch of the gradual progress of man's knowledge of the heavens. 

 The intricate details of observatory equipment were made clear by 

 means of numerous slides, and what has been done with this equip- 

 ment was fully shown by other slides. The address was a master- 

 ful yet simple review of the great field of science to which the 

 speaker has given most of his life. — Editor.
