But all these great plans were destined to a terrible defeat. Towards the end of the year 1839, still in the full vigour of his health and intellect, he suffered a paralysis of the optic nerve; and that eye, which for so long a term had kindled with critical interest over the volumes of so many literatures and so many languages, was doomed to pursue its animated course no more. Considering the bitterness of such a calamity to one whose powers were otherwise not in the least impaired, he bore on the whole his fate with magnanimity, even with cheerfulness. Unhappily, his previous habits of study and composition rendered the habit of dictation intolerable, even impossible to him. But with the assistance of his daughter, whose intelligent solicitude he has commemorated in more than one grateful passage, he selected from his manuscripts three volumes, which he wished to have published under the becoming title of "A Fragment of a History of English Literature," but which were eventually given to the public under that of "Amenities of Literature." He was also enabled during these last years of physical, though not of moral, gloom, to prepare a new edition of his work on the Life and Times of Charles the First, which had been for some time out of print. He contrived, though slowly, and with great labour, very carefully to revise, and improve, and enrich these volumes. He was wont to say that the best monument to an author was a good edition of his works: it is my purpose that he should possess this memorial. He has been described by a great authority as a writer sui generis; and indeed had he never written, it appears to me, that there would have been a gap in our libraries, which it would have been difficult to supply. Of him it might be added that, for an author, his end was an euthanasia, for on the day before he was seized by that fatal epidemic, of the danger of which, to the last moment, he was unconscious, he was apprised by his publishers, that all his works were out of print, and that their re-publication could no longer be delayed. In this notice of the career of my father, I have ventured to draw attention to three circumstances which I thought would be esteemed interesting; namely, predisposition, self-formation, and sympathy with his order. There is yet another which completes and crowns the character,--constancy of purpose; and it is only in considering his course as a whole, that we see how harmonious and consistent have been that life and its labours, which, in a partial and brief view, might be supposed to have been somewhat desultory and fragmentary.
