Mr. Threader opened a small wooden case lined with red velvet, took out a hand-scale, and began to weigh the Spanish and Dutch money against a calibrated brass weight, which, according to tiny but furious assertions graved on its face, was the Platonic ideal of what a pound sterling ought to weigh, as laid down some 150 years ago by Gresham. Mr. Orney took this as a signal to begin reading the minutes of the previous meeting, which had been held at Mr. Kikin’s town-house in Black Boy Alley a fortnight ago.
