26?. The Longitude. 



This we derive from the survey made to connect the Fulton and 

 Lyons stations, thus : — 

 Longitude of the Fulton Station, as ^ , ^, h. m. s. 



already given, - - 90 09 59.85 = 6 00 ?)9.99 



Lyons Station west in longitude, - + 44.29 = + 2.95 



Longitude, deduced,of Lyons Station, 90 10 44.14 = 6 00 42.94 

 Latitude, as before, - - 41 52 13.7 



Our survey, based on this result, gives two other positions in Lyons, 

 as follows, viz. — 



On Nicollet's map, this position is given -f 30" in latitude, and 

 -f 5' 50" in longitude greater than our observations give for our 

 station, which is nearly central of the city. 



On the other map mentioned, it is + 2' 02" in latitude, and + 3' 57" 



in longitude greater than ours. 



XV. ALBANY, ILLINOIS. 



This place is sometimes called "New Albany." It is situated on 

 the eastern shore of the Mississippi river. 



Both chronometers were carried from Fulton to Albany and back 

 to Fulton, between the 25th and 28th of March, 1858. Observations 

 were made at Albany on the nights of the 25th and 2Gth, both for the 

 latitude and the time. The longitude of this place is derived from 

 chronometric comparison with the meridian of Fulton. 



Station. — From this station to the intersection of the axes of Maple 

 and Main Streets, is S. 48° 51' 03" E. (true), and the distance is 89 

 feet. 



l5^ Observations for the Latitude. 1. IS58, March 25th. 



By 18 circum-meridian alliludcs of cc Hydra:', south, 

 combined with 5 altitudes of Polaris, north (clouds 

 prevented more observations on Polaris) - 41'' 47 23"
