Electrized oxygen loses its properties when placed in contact with iodid 
of potassium, but resumes them when again electrized. 
These facts demonstrate that the oxydizing power of electrized 
oxygen, is not due to the presence of any foreign body contained in 
the gas. 
6th. When pure and dry oxygen is enclosed in a series of tubes, and 
submitted to the action of electricity, it is found that the quantity of gas 
which becomes absorbable by the alcaline iodid increases during several 
hours in proportion to the time of electrification, but subsequently ap- 
ears to diminish, the spark probably destroying the effect which it at 
first produced. : 
7th. When small eudiometer tubes were filled with oxygen, and con: 
tained at the same time a substance capable of absorbing the electrized 
gas, as moist mercury, silver, or iodid of potassium, the oxygen was 
seen to diminish uniformly under the action of the electric spark, and 
frequently to be completely absorbed. 
th. ‘Tubes containing portions of moist iodid of potassium and of 
silver, were filled w pure oxgen, and then sparks passed through 
m during several days. The sparks at first very brilliant, became 
paler and paler, and finally almost invisible. At this moment the tubes 
were opened beneath the surface of water, when the water instantly
