April 30 d 7 h . After the vibration the box of the magnetometer was removed for the purpose of 

 removing an insect, but the insect could not be seen. The needle having been much vibrated from 

 exposure to the air, the observation of vibration at 7J b was made. 



May 3 a 8 h . The needle vibrated before this observation by the accidental approach of a mass of 

 iron introduced by visitors.
