I now come to the third consideration which we had to weigh--the situation of Portugal. It is perfectly true, as was stated by the honourable gentleman (Mr. Macdonald) who opened this debate, that we are bound by treaty to assist Portugal in case of her being attacked. It is perfectly true that this is an ancient and reciprocal obligation. It is perfectly true that Portugal has often been in jeopardy; and equally true that England has never failed to fly to her assistance. But much misconception has been exhibited during the last two nights, with respect to the real nature of the engagements between Portugal and this country: a misconception which has undoubtedly been, in part, created by the publication of some detached portions of diplomatic correspondence at Lisbon. The truth is, that some time ago an application was made to this Government by Portugal to 'guarantee the new political institutions' of that kingdom. I do not know that it has been the practice of this country to guarantee the political institutions of another. Perhaps something of the sort may be found in the history of our connexion with the united provinces of Holland, in virtue of which we interfered, in 1786, in the internal disputes of the authorities in that State. But that case was a special exception: the general rule is undoubtedly the other way. I declined, therefore, on the part of Great Britain, to accede to this strange application; and I endeavoured to reconcile the Portuguese Government to our refusal, by showing that the demand was one which went directly to the infraction of that principle of non-interference in the internal affairs of other States, which we professed for ourselves, and which it was obviously the interest of Portugal to see respected and maintained. Our obligations had been contracted with the old Portuguese monarchy. Our treaty bound us to consult the external safety of Portugal; and not to examine, to challenge, or to champion its internal institutions. If _we_ examined their new institutions for the sake of deriving from them new motives for fulfilling our old engagements, with what propriety could we prohibit _other_ Powers from examining them for the purpose of drawing any other conclusion? It was enough to say that such internal changes no way affected our engagements with Portugal; that we felt ourselves as much bound to defend her, under her altered constitution, as under the ancient monarchy, with which our alliance had been contracted. More than this we could not say; and more than this it was not her interest to require.
