Scrap of paper, possibly taken from a book, with the following quote:
There are two most valuable possessions which no search warrant can get at, which no execution can take away, and which no reverse of fortune can destroy; they are what a man puts in his head - knowledge, and into his hands - skill.
The quote is from Hiram Sibley.
Found in "Percy Bysshe Shelley" by John A. Symonds. Published by Harpers, no date listed.
