_August 14th._--The letter of John Russell's to which I have alluded was a very amiable and creditable production. As it was written in habitual confidence to his brother, it is impossible to doubt his sincerity. After speaking of his political intentions, and his probable exclusion from office, he proceeded to say that he looked forward with delight to his establishment at Endsleigh and to the opportunity of resuming some long neglected studies, and he said that he should be under the necessity of attending to those domestic economies which he had also not had time to think of; that he cared not for poverty; should have a sufficiency for comfort, and could always by writing and publishing add a few hundreds to his income. I was struck with the calm philosophy and the unselfish patriotism which his letter breathed, and with the grateful feelings he expressed at the happiness which seemed yet to be reserved for him. It is pleasant to contemplate a mind so well regulated, at once so vigorous, honest, and gentle; it cannot fail to be happy because it possesses that salutary energy which is always filling the mind with good food, those pure and lofty aspirations which are able to quell the petty passions and infirmities which assail and degrade inferior minds, and, above all, those warm affections which seek for objects round which they may cling, which are the best safeguard against selfishness, and diffuse throughout the moral being that vital glow which animates existence itself, is superior to all other pleasures, and renders all evils comparatively light.
