'Some three months ago there was found in the Earle of Strathmores ground six myles from Dundee some Roman Silver Denarij of which my Lord has got about 150, they are of Trajan, Hadrian, Antoninus Pius, and Commodus with Sabina and the two Faustinas. I am useing endeavours to get what I can of them. I keep a constant Correspondence with Mr Charleton at London, who knows what Medals I want, and buyes them for me as they come in his way so that I have now in my Cabinet upwards of 900 different silver denarij of which 200 are Consular. I hope by your next to get ane Account of the Coyns ye have collected, and if ye please to send the varieties of your Country Fossils they will be acceptable.'
