There is still, the Courier of last night says, considerable
doubt whether the Northern Powers, Prussia and Russia, will permit coercive measures to be employed against the King of Holland. The argument urged or alleged is, that the King has recognized the boundaries of Belgium; and that the evacuation of the citadel of Antwerp and the toll on the Scheldt are matters for negotiation between him and LEOPOLD, as is the payment of the debt. In short, by eighteen months' conferring and protocolizing, the King has been brought to acknowledge the principle of the deed of se- paration; and Belgium and he ought now to settle whether, how, and when he is to act on it. The Powers, it is evident, if they leave the Dutch and Belgians in their present position, will de facto leave the whole matter in dispute precisely where they found it. The Brussels journals say that Sir ROBERT ADAIR has been beard to assert that all the demonstrations of England and France were a mere show. Sir ROBERT probably did not say this, but we believe there are a great many shrewd people at home and. abroad that have all along thought it. The anniversary of the Belgic Revolution was held on the 28th; on which occasion, King LEOPOLD presented a standard if honour to the tations of the several communes.
