DECLINATION. Magnet untouched, April 14¢, 1846—May 1847. 
Biri~uar. Observed 2™ after the Declination, s=0:000135. BaLance. Observed 3” after the Declination, s=0:000010. 
+ Extra Observations made. ; 
The declinometer was noted 25° 02/52, but from the steadiness of the instruments during the day it was believed that 
the reading was 10 scale divisions in error ; it has been altered accordingly.
