The present Declaration shall be ratified as soon as possible. The ratifications shall be deposited at The Hague. A ‘ procès-verbal ‘ shall be drawn up on the receipt of each ratification, of which a copy, duly certified, shall be sent through the diplomatic channel, to all the Contracting Powers. The non-Signatory Powers may adhere to the present Declaration. For this purpose they must make their adhesion known to the Contracting Powers by means of a written notification addressed to the Netherlands Government, and communicated by it to all the other Contracting Powers. In the event of one of the High Contracting Parties denouncing the present Declaration, such denunciation shall not take effect until a year after the notification made in writing to the Netherlands Government, and by it forthwith communicated to all the other Contracting Powers. This denunciation shall only affect the notifying Power. In faith of which the Plenipotentiaries have signed the present Declaration, and affixed their seais thereto. Done at The Hague, 29 July 1899, in a single copy, which shall be kept in the archives of the Netherlands Government, and of which copies, duly certified, shall be sent through the diplomatic channel to the Contracting Powers.
