PEELIMINAEY NOTICE. 7 



they should be published in a shape that will place them 

 within everybody's reach. The volume of ' Proceedings/ 

 edited in French only, and entirely made up of papers on 

 special matters, could not serve this purpose. I have con- 

 sequently made up my mind to publish, with the assent 

 of the Committee, this second edition of my pamphlet, in 

 French, in German, and in English. 



The Introduction does not differ from that of the first 

 edition. The text of the articles is the one adopted by the 

 Congress. The Commentary has been modified in accord- 

 ance with the changes made in the text of the articles, and 

 completed by the addition of fresh information, or of con- 

 siderations that have suggested themsdves since the sittings. 

 Those who wish to examine the different questions more 

 particularly will do well to consult the volume of ' Proceed- 

 ings,' together with the present treatise. The details of the 

 discussion, published in the ' Proceedings,' necessarily com- 

 plete my work, in which, On the other hand, are to be found 

 the Introduction and the Commentary, that do not appear 

 in the official volume. Moreover, the two works being of 

 the same form, it will be easy, for any one so disposed, to 

 annex this pamphlet, printed in any one of the three lan- 

 guages above mentioned, to the volume of the ' Proceed- 

 ings.'
