 only the purport of the clauses of treaties is given. English is the language used throughout.

'That these Engagements', says the author, 'have been contracted, in many instances, with the avowed object of maintaining the Balance of Power, may be readily tested by referring to the Index under that heading.'

Many of these engagements have been preceded or followed by European Conferences, and descriptions are given in some detail of the deliberations of the most important of these. References are given to the volumes of the State Papers in which the Protocols are to be found. The work contains, further, Declarations of War; Treaties for the European Guarantee of Independence and Neutrality of certain States; Decrees annexing Territories, and Protests of the Possessors against Annexations.

Owing to the frequent references to the Vienna Congress Treaty of 1815 in such Protests, the Index gives a key to all such references in subsequent European Documents.

In an Appendix are given copies of Treaties, or extracts from Treaties, which were concluded before 1814, but are alluded to in the body of the work as being still valid, and there is a reference to the volumes of the State Papers, in which will be found extracts from and references to other documents not themselves inserted in the body of the work in order of date.

The Index gives exact reference to every name and to every subject mentioned in the several Treaties or other international documents contained in the work.
