Sept. 264.—The Declination and Bifilar Magnetometers were supplied with closely fitting rectangular boxes, placed within the eyli 
drical boxes, for the purpose of destroying currents of air. The boxes of all the Magnetometers were covered inside and outside wi : 
gilt paper. 
The box of the Balance Magnetometer was removed after the observation at 4», and replaced before that at 6%,
