Belwille did noé agree, with the mean latitude actually observed at Bairdt, 
at it ought to have done, but differed from it, ten seconds; had it differed 
only three or four seconds, we should have been content to sacrifice perfect 
agreement to gain time, and indeed it must be confessed, that having regard 
to the object in question, an uncertainty of three or four hundred feet in 
sixty-one miles and a half miles was not much; it would affect the distances 
of the remotest snowy peaks only to the amount of about 600 feet, in 
the whole; and the nearer peaks, less in proportion: the heights would 
be very little altered, nor would the uncertainty even of 10 or 330 yards 
materially affect them, but. the. latitudes and longitudes, would be 
uncertain and unsatisfactory.. Much chagrined at the disagreement, we 
were at a loss what steps to take; whether to consider the latitude of 
Belville, as satisfactorily settled, and that of the other two stations as erro 
neous, or to dividé the error equally between the three. Still suspecting 
that some oversight had taken place, though none seemed palpable, we 
_ determined to try a second proof station, in hope it might throw some light 
on the subject: for this purpose the mountain of Surkunda was fixed on, 
which is distant from Belviile, 2,836,212 feet and 8,300 feet higher than it. 
There, latitudes, angles and Azimuths were observed, and again the ob- 
served, and computed latitudes differed, to the amount of some seconds, and 
in the same manner as at Bairdt, the computed arc proving greater, than 
the observed. On the Warté mountain, also which is distant nearly north 
from the Chir’, 111,634 feet, and 1016 feet lower than it, a station was esta- 
blished, when operations, similar to those noted above, were effected: the 
best latitudes there were observed by Lieutenant Hergerr, and though not 
| so numerous as those at the Chit, Beluille, Bairdt and Surkunda stations,
