and methods. In this essential task he will j5nd no surer or 

 better guide than the original papers of J. Willard Gibbs. 



In the work of producing this Commentary we have been 

 fortunate in enlisting the cooperation of a number of very able 

 collaborators, to each of whom has been entrusted a special 

 section of the Volume. To all these collaborators we desire to 

 express our very high appreciation of the work which they have 

 accomphshed. 



Our work as Editors has been greatly lightened by the extreme 

 care which the members of the Gibbs Committee have bestowed 

 on the correction of the proofs and on many other matters of 

 importance. For this valuable help we are extremely grateful. 



Last, but not least, we wish to express, on behalf of ourselves 

 and our collaborators, our deep sense of the honor which the 

 Gibbs Committee has conferred upon us all. Should our joint 

 labors succeed in liberating the beautiful work of Gibbs from 

 the abstract tour d'ivoire in which it has been for so long con- 

 cealed from many students of science, then great will be our 

 reward.
