Stubbs. — Conductivity of Aqueous Solutions of darhon-dioxifie. 21 



Hydrate not yet formed. Between 11 a.m. and 12.25 p.m. temperature 

 kept at 0°. At 12.25 p.m. the following reading was obtained : — 



During the formation of the hydrate the pressure remained constant. 



B. Pressure released from 30 to 25 atmospheres, temperature being kept 

 low. A series of determinations of the conductivity with varying tem- 

 peratures, at the constant pressure of 25 atmospheres. The hydrate decom- 

 posed between 4° and 10°, and was not re-formed when the temperature 

 was lowered. 



C. Temperature having been kept some hours at 0°, and hydrate ap- 

 parently re-formed, the following series of readings was made (pressure = 

 25 atmospheres) : — ■ 



Previously determined.
