vast universe they have lost their little prejudices and personal
preferences. I strengthen their judgment, assiduously exercise their

to habits of accuracy, patience, and perseverance by long scientific
research; and at the moment when I ought to find them useful as

His friend pondered deeply upon the vexatious problem.

"You say," he remarked, "that this unfortunate attraction exists in
spite of philosophical training,--that it is exerted towards the
antipodes of their previous associations; that, as they have been
trained to yield only to well-grounded syllogisms, it is the illogical

"Then my way becomes clearer. It surely cannot be unknown to you, sagest
of students, that in physical science we oppose a plenum to a vacuum,
in medicine we supply a deficiency of saline secretions by the common
expedient of salt. Wherefore not apply our knowledge painfully gleaned
from lower science to the study of these more complicated phenomena? The
