On some occasions, although very rarely, we have seen him deeply agitated.  We have seen him grow so pale and wan, that his appearance was actually corpse-like.  But even in moments of the most intense emotion, he remained concentrated within himself.  A single instant for self-recovery always enabled him to veil the secret of his first impression.  However full of spontaneity his bearing afterwards might seem to be, it was instantaneously the effect of reflection, of a will which governed the strange conflict of emotional and moral energy with conscious physical debility; a conflict whose strange contrasts were forever warring vividly within.  The dominion exercised over the natural violence of his character reminds us of the melancholy force of those beings who seek their strength in isolation and entire self-control, conscious of the uselessness of their vivid indignation and vexation, and too jealous of the mysteries of their passions to betray them gratuitously.

He could pardon in the most noble manner.  No rancor remained in his heart toward those who had wounded him, though such wounds penetrated deeply in his soul, and fermented there in vague pain and internal suffering, so that long after the exciting cause had been effaced from his memory, he still experienced the secret torture.  By dint of constant effort, in spite of his acute and tormenting sensibilities, he subjected his feelings to the rule rather of what ought to be, than of what is; thus he was grateful for services proceeding rather from good intentions than from a knowledge of what would have been agreeable to him; from friendship which wounded him, because not aware of his acute but concealed susceptibility.  Nevertheless the wounds caused by such awkward miscomprehension are, of all others, the most difficult for nervous temperaments to bear.  Condemned to repress their vexation, such natures are excited by degrees to a state of constantly gnawing irritability, which they can never attribute to the true cause.  It would be a gross mistake to imagine that this irritation existed without provocation.  But as a dereliction from what appeared to him to be the most honorable course of conduct was a temptation which he was never called upon to resist, because in all probability it never presented itself to him; so he never, in the presence of the more vigorous and therefore more brusque and positive individualities than his own, unveiled the shudder, if repulsion be too strong a term, caused by their contact or association.

The reserve which marked his intercourse with others, extended to all subjects to which the fanaticism of opinion can attach.  His own sentiments could only be estimated by that which he did not do in the narrow limits of his activity.  His patriotism was revealed in the course taken by his genius, in the choice of his friends, in the preferences given to his pupils, and in the frequent and great services which he rendered to his compatriots; but we cannot
