'Morning, finishing the index; till ten, to visit Mr. St. John, at Plasterers’-hall, who showed me his collections of natural curiosities, formed stones, &c.; but I was best pleased with his Roman coins, of which he had some very rare; and he was so kind as to present to me a Diadumenianus, of whom I had not one before.' (Hunter 1830, vol. 2, p. 257; Burnett 2020b, pp. 860 n. 66, 862 n. 102)
