 observer, appreciation of the unspeakable value of a fact. 



Still the certainty remains that for all productive purposes 

 of Natural History the last fifteen years of his life yielded 

 constantly less and less. Genius works many miracles, but

 children* no private means, and the public library of a Uni- 

 versity to administer. As the library grew larger, his op- 

 portunities grew less, and it is pathetic to read in his cor- 

 respondence the gradual waning of his hopes of release.
