posts on this board, and the circuit closed, it required only the simple movement of 

 sliding a switch-button to cut off or put on either circuit, and thus send the chrono- 

 metric break, or receive that of the connected station on the chronographic sheet, as 

 desired. The nights of the ist, 3d, 8th, gth, loth, nth, and 12th were occupied on 

 latitude, in which time 257 results were obtained. The 5th, i4th, i6th, i8th, igth, and 

 2 1 st were successively put in on longitude. There were several other evenings when 

 efforts were made in this direction, but failed from causes beyond my control. Mr. 

 Austin did the observing at Salt Lake, while the observations at Cheyenne were made 

 by myself, and also the longitude reductions for both stations. Prof. W. A. Rogers, 

 of Harvard College Observatory, computed the latitude-observations, and they were 

 subsequently revised, partially recomputed, and formulated by Dr. Kampf.
