'I Hope Mr Elstob ha’s been so kind (upon my entreaty) as to have put the business of weighing & copying the old Roman Weights into some Forwardness, by this Time. And if I had the Weights of them all, soo: I could wait upon my Lord with that account, which will very much oblige him.' (Wanley 1989, pp. 147-50, letter 72; Burnett 2020b, pp. 430 n. 392, 1248 n. 663)
