large; perhaps because no positive discharges were taken with 

 the negatives. V— in air and oxygen shows the same ten- 

 dency to vary more than V-f , though it is not nearly so 

 marked. V + , on the other hand, varies more han in 

 hydrogen ; but this may be due to the formation of ozone. In 

 carbon dioxide the effect seems to be absent,
