During February and March, 1880, the old observatory building, 

 which stood a few feet west of the main university edifice, was moved 

 and enlarged. It now stands on the beautiful eminence in the campus 

 near the chalybeate spring. The meridian line of each pier now passes 

 between the university building and the i)resident's mansion. In this 

 position a good horizon is secured. In the old position the horizon was 

 obstructed on the north by the scientific building, and on the east by 

 the university building. 



The old dome was found to be too small for the equatorial recently pur- 

 chased, and a brick addition was made at the east end for the accom- 

 modatiou of this instrument. The whole building is G3 feet long from 

 east to west, and fronts east. 



The present greatly improved condition of the observatory is due to 

 the liberality of the president, Dr. S. S. Laws, who, for the advance- 

 ment of astronomical science, has given to the university more than 

 $2,000, in order to procure the telescope and put it in complete working 

 order, and to move and enlarge the observatory building.
