to hear this IcmvikmI scientist repeatiiii;' pages of seiitiiiiental verse, 
it was still more so to note tliat not only could he on occasion 
excel in the art of colorless polite conversation, hut invarialdy 
exeiteil the ailniiration of his hearers liy his accurate memory U)V 
the thousand tiitles which form its staple, and. in fact, act- 
ually enjoyed it, Xe\'ertheless. a word was enough to divert him 
from this liuht |)astime, and he would lose the smiling presence 
which accompanied his iiadinage and drop hy instirict into a 
thoughtful and well exjiressed monologue. 
lie had a keen sense of the humorous and a loud ami conta- 
gious laugh v.hicli inspirctl in others as much hilarity as the sally 
wliich called it forth. His nature was emotional, but controlled 
hy strong and well l)alaiiceil reasoiung i)ower, so that no serious 
view of his on any scii'ntitic subject was intiueuced by it. It 
follows that where this reasoning power was not exercised, as in 
the ordinary small woiiies and mishai)s of life he exhibited an 
extreme passion, tenderness, or sensitiveness. This charac- 
teristic while it enaliled him to enjoy much that was unfelt by a 
coarser nature, was nevertheless, the cause to him of extn-me 
sutfering from causes which would have made no impression on 
most men. 
His weaknesses were not those which could detract from his 
greatness, nor did they contain anything sordid or hateful, while 
the salient points which distinguished him above others [)laced 
him in that indetinabh- class of great men whose thoughts have 
moulded our ei>nturv. It was an instructive lesson in psychology 
to stand lieside him and observe how smoothly and forcefully his 
mind worked on sulijects of the greatest ditliculty. and how 
beautifully it recorded its work in well chosen sentences ca<h'nced 
to express the smallest variations of meaning, and so beautifully 
eleai' as to reiidci- further intei'pretation uiuiecessarv even for the 
least intidligenl of his hearers.
