If you have a grateful heart (which is a miracle amongst you statesmen), show it by directing the bearer to the best wine in town, and pray let not this highest point of sacred friendship be performed slightly, but go about it with all due deliberation and care, as holy priests to sacrifice, or as discreet thieves to the wary performance of burglary and shop-lifting. Let your well-discerning palate (the best judge about you) travel from cellar to cellar and then from piece to piece till it has lighted on wine fit for its noble choice and my approbation.

Letter to the diplomat Henry Savile (1673-1674).
