later give the same observations taken at longer intervals of 

 time. The volumes of gas condensed are in cubic centimetres 

 at 0° C. and 0*76 metre pressure; the temperatures are given 

 in centesimal degrees; the unit of pressure of mercury is 

 5 millim., and the unit of time 3 days (72 hours). Column I. 

 of the Table contains the time, column II. the total volumes 

 of gas condensed, column III. the temperature, and column IV. 

 the pressures at the times in column I. 



The numbers in the following Table are graphically ex- 

 pressed in curves 1, 2, and 3, PL V. fig. 2. Curve 1 gives the 

 temperatures, curve 2 the total condensation of gas,and curve 3 

 the pressure; the whole of the periods of observation are ex- 

 pressed by abscissae, and the numerical units corresponding to 

 Table IV. by ordinates.
