Holmes' Latin quotation

“I have all the facts in my journal, and the public shall know them. In the meantime you must make yourself contented by the consciousness of success, like the Roman miser —
“Populus me sibilat, at mihi plaudo Ipse domi simul ac nummos contemplar in arca.” (
Sherlock Holmes)

Explanation:
The quotation is from Horace, Book 1, Satire 1.
"The public hisses at me, but I applaude myself in my own house, and simultaneously contemplate the money in my chest."
