That unfortunate gentleman was undoubtedly a man of genius—full of ideal beauty and enthusiasm.  And yet there was some defect in his understanding by which he subjected himself to the accusation of atheism.  In his dispositions he is represented to have been ever calm and amiable; and but for his metaphysical errors and reveries, and a singular incapability of conceiving the existing state of things as it practically affects the nature and condition of man, to have possessed many of the gentlest qualities of humanity.  He highly admired the endowments of Lord Byron, and in return was esteemed by his Lordship; but even had there been neither sympathy nor friendship between them, his premature fate could not but have saddened Byron with no common sorrow.

Mr Shelley was some years younger than his noble friend; he was the eldest son of Sir Timothy Shelley, Bart., of Castle Goring, Sussex.  At the age of thirteen he was sent to Eton, where he rarely mixed in the common amusements of the other boys; but was of a shy, reserved disposition, fond of solitude, and made few friends.  He was not distinguished for his proficiency in the regular studies of the school; on the contrary, he neglected them for German and chemistry.  His abilities were superior, but deteriorated by eccentricity.  At the age of sixteen he was sent to the University of Oxford, where he soon distinguished himself by publishing a pamphlet, under the absurd and world-defying title of The Necessity of Atheism; for which he was expelled from the University.

The event proved fatal to his prospects in life; and the treatment he received from his family was too harsh to win him from error.  His father, however, in a short time relented, and he was received home; but he took so little trouble to conciliate the esteem of his friends, that he found the house uncomfortable, and left it.  He then went to London; where he eloped with a young lady to Gretna Green.  Their united ages amounted to thirty-two; and the match being deemed unsuitable to his rank and prospects, it so exasperated his father, that he broke off all communication with him.

After their marriage the young couple resided some time in Edinburgh.  They then passed over to Ireland, which being in a state of disturbance, Shelley took a part in politics, more reasonable than might have been expected.  He inculcated moderation.

About this tune he became devoted to the cultivation of his poetical talents; but his works were sullied with the erroneous inductions of an understanding which, inasmuch as he regarded all the existing world in the wrong, must be considered as having been either shattered or defective.

His rash marriage proved, of course, an unhappy one.  After the birth of two children, a separation, by mutual consent, took place, and Mrs Shelley committed suicide.
