oxygen and carbon monoxide, the subject has received 

 thorough investigation at the hands of such men as 

 Pictet, Wroblewski, < Hskewski, Dewar, Linde, 

 Hampson and others. The various reports and com- 

 munications relating to the work, however, have been 

 more or less scattered amongst the world's literature, 

 and the author of the present book has done good 

 service in bringing them together in such an interest- 



work adequately discussed. Chapter three contains 

 a detailed account of Andrews' well-known experi- 

 ments, and is therefore an important one, for, as the 

 author states, with the observations of Andrews a new 

 era begins. The difficult question as to the conditions 

 of gases at their ciitical points are here disci 

 the views of various experimenters being put forward.
