Observations for the Time at 3Hlwavkee Station No. 2, 

 July 1st, 1858. 



This station was more convenient to my lodgings than No. 1. It 

 is the centre, or point of intersection of the public walks, of the Court 

 House Square. 



From Ihis point, if we run due east 235 feet, and then due north 

 29 feet, it will bring us perpendicularly under the apex of the steeple 

 of the Roman Catholic Church on Jackson street. Hence, this steeple 

 is 0".29 north of the parallel, and 3". 165 of arc = 05.21 of time east 

 of the meridian of this observing station No. 2. 



A point perpendicularly under the middle of the dome of the court 

 house is due north 123 feet = + 1".2 of latitude from this station 

 No. 2. 



The night was not very favourable for observations for the time. 

 Passing clouds frequently obscured the stars which I desired to observe 

 near the east and west prime vertical for that object. I could only get 

 a single observation on cc Andromedte in the east, to halance against 

 5 observations on « Bootis, and 8 on o& Coronte Borealis, both in the 

 west, for computing the time this night. 



The sky to the north and the south was clearer, and hence more 

 favourable to the observations for the latitude. ^ 



1858, July 1st. At Milwaukee Station No. 2. 



Sidereal chronometer No. 2557, fast: 



By 5 observations on x Bootis, west h. m. s. 

 (at 18A. 36m.) - - 1 01 33. 



By 8 observations on ex. Coronse Bo- 

 realis, also west (at 19/i. 03m.) 1 01 32.7 



h. m. s. 



By 13 observations on 2 west stars (at 18/i. 507/z.) + 1 01 32.85 



By 1 observation on £«Andromedoe, east (at 20/t. 50m.) -f 1 01 33.31 



Result — Chronometer No. 2557, fast of sidereal time 



for this station (at 19A. 53m.) - - + 1 01 33.08 



The following telegraphic signals were passed, before the observa- 

 tions for the time were made here. The weather was so cloudy, that 

 no observations on the stars could be made previous to the time of 

 night at which the telegraph was at our command for the signals. 

 We had first to pass the signals, and take the chances of getting the 

 time from observation afterwards.
