Never did any one leave behind him more copious materials for enabling others to put together a narrative which might be the history, not indeed of his times, but of the man himself.

For in the first place he so soon showed promise of being one who would give those among whom his early years were passed reason to be proud, and still more certain assurance that he would never afford them cause for shame, that what he wrote was preserved with a care very seldom bestowed on childish compositions; and the value set upon his letters by those with whom he corresponded naturally enough increased as years went on.

And in the next place he was by nature so incapable of affectation or concealment that he could not write otherwise than as he felt, and, to one person at least, could never refrain from writing all that he felt; so that we may read in his letters, as in a clear mirror, his opinions and inclinations, his hopes and affections, at every succeeding period of his existence.

Such letters could never have been submitted to an editor not connected with both correspondents by the strongest ties; and even one who stands in that position must often be sorely puzzled as to what he has the heart to publish and the right to withhold.
I am conscious that a near relative has peculiar temptations towards that partiality of the biographer which Lord Macaulay himself so often and so cordially denounced; and the danger is greater in the case of one whose knowledge of him coincided with his later years; for it would not be easy to find a nature which gained more by time than his, and lost less.

But believing, as I do, (to use his own words,) that "if he were now living he would have sufficient judgment and sufficient greatness of mind" to wish to be shown as himself, I will suppress no trait in his disposition, or incident in his career, which might provoke blame or question.
