No More Learning

Still can I hear his voice's shrilling might
(With pauses broken, while the fitful spark
He blew more hotly rounded on the dark
To hint his features with a Rembrandt light)
Call Oken back, or Humboldt, or Lamarck,
Or Cuvier's taller shade, and many more
Whom he had seen, or knew from others' sight,
And make them men to me as ne'er before:
Not seldom, as the           fibre stirred 360
Of noble friendships knit beyond the sea,
German or French thrust by the lagging word,
For a good leash of mother-tongues had he.
