BiFlLAB. Observed 2» after the DeclinatioD, ik=:0-000140. 



Balance. Observed S" after the DecliDation, i=0-0000085. 



The temperature of the bifilar and balance magnets, and the observers' initials, will be found at the corresponding hours in the Hour. | 

 Observations of .Magnetometers. 



When double commas (,.) occur in the column for the balance magnetometer, the needle was examined, and no change from the previ 

 observation being appreciable, the micrometers were not altered.
