TABLE: 25. Comparison of surface areas. Chloroform. 



Mean, A, 0.040. Mean, B, 0.0348. Ratio of surfaces, 7.1: 6.2. 

 Temperature, 16.6, C. Pressure, 763.9. Rel.itive humidity, 45 per cent. 



Table 26 indicates that the relative evaporation of liquids is 

 approximately constant, and is independent of the velocity of the 

 wind over the exposed surface. In the above work the tempera- 

 ture was different under the two conditions by an average of 

 about 12 C. It was determined that in the case of ether a 

 difference of i C. corresponded to a difference of about o.ooi 

 gram per minute.
