Mercury and The Tradesmen

When Jupiter was creating man, he told Mercury to make an infusion¹（灌输，浸泡） of lies and to add a little of it to the other ingredients which went to the making of the tradesmen. Mercury did so, and introduced an equal amount into each in turn-the tallow（牛脂，兽脂）-chandler（杂货店）, and the greengrocer, and the haberdasher（杂货商）, and all, till he came to the horse-dealer, who was last on the list, when, finding that he had a quantity of the infusion still left, he put it all into him. This is why all tradesmen lie more or less, but they none of them lie like a horse-dealer.
