64 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



tailed observations and drawings of a number of auroras have been 

 taken. Several spectroscopes have been used in the examination of 

 the aurora and zodiacal light, with results agreeing with those of 

 previous observers. A few meteorological observations have also 

 been taken. 



No publications have been made. 



Gettysburg, Pa.: Observatory of Pennsylvania College. 



Professor Philip M. Bikle, Director. 



The personnel of the observatory consists of Professor P. M. Bikle 

 as director, and U. A. Hankey, a member of the senior class, as as- 

 sistant. The principal instruments are: (1) An Equatorial Telescope, 

 (2) Transit Instrument, and (3) Chronometer (Negus). The observa- 

 tions during the past year were principally for procuring correct 

 time. The transit of Mercury was observed in Ma} r , the final (inter- 

 nal and external) contacts with great care. The observations for 

 the coming year will be chiefly in the line of those of the past, our 

 observatory being used largely for the purpose of instruction in con- 

 nection with the study of astronomy by the senior class. There have 

 been no publications during the year. 



Glasgow, Mo. : Morrison Observatory. 



Professor C. W. Pritchett, Director. 



In reply to your circular asking for information about this observ- 

 atory, I have to say that my only assistance in astronomical work is 

 from my son, a youth of fifteen. 



Work on the Equatorial. 1. During the year we have continued 

 the measures of close double stars, not systematically, but in some 

 special directions. 2. Several series of observations on the satellites 

 of Jupiter and Saturn. 3. Micrometric measures of diameters of 

 Jupiter, Saturn, Mercury, and Uranus. 4. Of special observations, I 

 may mention the occultation of Venus, December 8 of last year; dis- 

 appearance of Saturn s ring, February 6 ; transit of Mercury, May 

 5-G ; and the solar eclipse, July 29. 5. A series on the companions 

 of Sirius. 6. A number of occupations of stars. 



Meridian -Circle Work. 1. Regular observations for time. 2. A 

 series of altitudes of circumpolar stars for latitude determination. 

 3. Observations of the moon and culminating stars. 



Meteorological observations have been made and recorded three 

 times daily. We have made no publications, except those in the 

 astronomical journals. I might, add that a la rue amount of work 

 has been expended on the instrumental constants.
