The vibrations in this experiment are as follows : 
In free air, the commencing- series 86306.46 ; Barom. 29.026 ; Therm. 44°.25 
the concluding series . 86306.47 ; Barom. 28.967 ; Therm. 45 .7 
Mean . . . 86306.46 ; Barom. 28.996 ; Therm. 44 .97 
In air within the receivers 86306.31 ; Barom. 28.986 ; Therm. 45 .95 
Whence the vibrations within the receivers are in this experiment in defect, 
0.15 per diem.
