I was in the playhouse one night when _Ca Ira_ was called for. I was in the middle of the pit, and from the pit the clamour arose. One or two persons, with whom I occasionally associate, were of the party, but I neither knew of, nor joined in the plot, nor at all opened my lips to hiss or huzza that, or any other political tune whatever. I looked on myself as far too obscure a man to have any weight in quelling a riot, and at the same time as a person of higher respectability than to yell to the howlings of a rabble. I never uttered any invectives against the king. His private worth it is altogether impossible that such a man as I can appreciate; but in his public capacity I always revered, and always will with the soundest loyalty revere the monarch of Great Britain as--to speak in masonic--the sacred keystone of our royal arch constitution. As to Reform principles, I look upon the British Constitution, as settled at the Revolution, to be the most glorious on earth, or that perhaps the wit of man can frame; at the same time I think, not alone, that we have a good deal deviated from the original principles of that Constitution,--particularly, that an alarming system of corruption has pervaded the connection between the Executive and the House of Commons. This is the whole truth of my Reform opinions, which, before I knew the complexion of these innovating times, I too unguardedly as I now see sported with: henceforth I seal up my lips. But I never dictated to, corresponded with, or had the least connection with any political association whatever. Of Johnstone, the publisher of the _Edinburgh Gazetteer_, I know nothing. One evening, in company with four or five friends, we met with his prospectus, which we thought manly and independent; and I wrote to him, ordering his paper for us. If you think I act improperly in allowing his paper to come addressed to me, I shall immediately countermand it. I never wrote a line of prose to _The Gazetteer_ in my life. An address, spoken by Miss Fontenelle on her benefit night, and which I called "The Rights of Woman," I sent to _The Gazetteer_, as also some stanzas on the Commemoration of the poet Thomson: both of these I will subjoin for your perusal. You will see they have nothing whatever to do with politics. As to France, I was her enthusiastic votary in the beginning of the business. When she came to shew her old avidity for conquest by annexing Savoy and invading the rights of Holland, I altered my sentiments. This, my honoured patron, is all. To this statement I challenge disquisition. Mistaken prejudice or unguarded passion may mislead, have often misled me; but when called on to answer for my mistakes, though no man can feel keener compunction for them, yet no man can be more superior to evasion or disguise.--I have the honour to be, Sir, your ever grateful, etc., ROBT.
