The following letters will exhibit the genuine character of Mr. Southey through the whole of his literary life. In the earlier periods, a playful hilarity will be found; but this buoyancy of spirit, when prevailing to excess, (in the constitutionally cheerful, such as was Mr. S.) is generally modified, if not subdued, by the sobering occurrences of after life. Letters, like the present, possess some peculiar advantages. Whenever, as in this instance, epistles are written through a series of years, to one person, the writer's mind is presented, under different aspects, while the identity is preserved. This benefit is greatly diminished, when, in a promiscuous correspondence, letters are addressed to a diversity of persons; often of different habits, and pursuits, where the writer must be compelled, occasionally, to moderate his expressions; to submit in some measure to mental restraint, by the necessity he is under to curb the flow of his spontaneous feeling. Besides this freedom from comparative bondage, one other advantage is derived from these continuous, and unconstrained letters to a single friend. A writer, in all his letters, from addressing one, for the most part, of congenial sympathies, expresses himself with less reserve; with more of the interior poured out; and consequently he maintains a freedom from that formality of essay-like sentences, which often resemble beautiful statues, fair, but cold and wanting life. When, during the Revolutionary war, disgusted with the excesses of the Trench, Mr. Southey saw it right, from a Foxite, to become a Pittite, some who did not know him, ascribed his change of sentiment to unworthy motives; of this number was my esteemed friend the late Rev. John Foster, who whilst freely admitting Mr. Southey's great attainments and distinguished genius, regarded his mind as injuriously biassed. He thought Mm a betrayer of his political friends. No countervailing effect was produced by affirming his uprightness, and the temperance with which he still spake of those from whom he was compelled to differ. He was told that Mr. Southey was no blind political partisan, but an honest vindicator of what, in his conscience, he believed to be right--that no earthly consideration could have tempted him to swerve from the plain paths of truth and justice. An appeal was made to his writings, which manifested great moderation: and as it respected the Church, the London, and the Baptist Missionary Societies, it might be said, that he courageously stood forth to vindicate them in the Quarterly, at a critical time, when those Societies had been assailed by Sydney Smith, in the Edinburgh Review. All proved unavailing. At length I submitted to Mr. Foster's inspection, Mr. Southey's correspondence for more than forty years, where, in the disclosure of the heart's deepest recesses, the undisguised character distinctly appears. He read, he admired, he recanted. In a letter to myself on returning the MS. he thus wrote: "The
