On examining these tables, and the curves which graphically repre- 

 sent them, we see that here also the capillary action of the liquid is 

 weakened by a gas impinging upon its surface, even at low tempera- 

 tures, and again we see that the capillarity is reduced to zero before the 

 liquid is really gaseous, showing that like alcohol the surface tension 

 of carbon disulphide is destroyed by the activity of the molecules of 

 the gas overlying it. The curve for carbon disulphide and hydro- 

 gen, XIV, fig. 3, should not be really a straight line, but a number 

 of accidents happened during these experiments, and the curve is 

 made up from many readings from different manometers, that for the
