Table I.—CO and CL (in the glass bulb). 
The glass bulb was filled with the gases in the dark. The gases freshly prepared 
mercury and of the cone. S0 4 H 2 (sp.gr. 1*84)) on the manometer was 505'4 millims., 
temperature of the room 24 0, 5. On leaving the glass bulb in the dark from Friday, 
temperature of the room to 22 3, 3. The manometer rose from 510 to 513‘5, i.e., by 
of barometer and temperature of the room. Thus during three days no combination 
Barometer, 763'2 (21 0 ‘7), temperature of room, 22 0, 3. Manometer fell to 51‘17, i.e., 
variation of temperature of the room and of the atmospheric pressure. The vessel
