.generation, and to discuss scientific questions with them so as 
to stimulate thought and originality of manner of viewing phe¬ 
nomena, when well done, reacts as a powerful stimulus upon 
the teacher himself, renewing his youth as it were, spurring 
him on to new endeavor and in fact often leading to sugges¬ 
tions culminating in new ways of attacking difficult problems. 
Think, for example, of the laboratory of Justus Liebig, who 
himself was a man of real creative power, and personally con¬ 
ducted many researches, was he not helped in his work by the 
large numbers of enthusiastic, industrious young men that 
thronged about him and afterwards carried on further the 
work of their great master ? His compelling eye and energetic 
manner drew students to him as if by magic spell. Truly 
such a teacher is practically always acting in accord with the 
immortal lines of Coleridge, which he put into the mouth of 
the Ancient Mariner—“The moment that his face I see I know 
the man that must hear me, to him my tale I teach.” Then 
there is Michael Faraday, that great experimental genius whose 
simple, direct mode of attacking and solving experimental 
difficulties will ever remain as a model. Did not he seem to 
long to give expression to his thoughts to others, did he not 
almost yearn to teach ? Let his lectures on the life history 
of the tallow candle speak for themselves. He exemplified, too, 
the proper type of mind of a scientific man. To him facts 
and laws were of utmost importance, while hypotheses and 
theories were hut tools that lasted for a day. Preconceived no¬ 
tions he always regarded as an enemy to real scientific progress. 
He was no worshiper of authority in scientific matters. He 
calmly dared to describe his experiments and draw the conclu¬ 
sions to which they led, though these conflicted with those of so- 
called authorities. The disdain with which the great Berzelius 
dared to characterize Faraday’s work upon which he based his 
well-known law of electrolysis is known to all; yet Faraday was 
undismayed, and future, years revealed he was indeed in the 
right.
