Unused and unpublished preface for J. Greaves, Discourse of the Roman Foot and Denarius (London 1647): 'And here I may not pretermit without honourable mention the endeavours of two excellent men. The one an English man & ye worthy founder of Caius College, in Cambridge, wch beares his name, who in his preface as I remember, before Celsus makes mention of a tract finished by him in Italy De vera denarij ratione. What has become of this tract I could never learne, his Celsus wth many variae lectiones out of ye best MSS is in ye hands of Rhodius a Dane, who promised me att Padua to publish it, & I hope will performe it. The other is Monsieur Peiresc, once a Gentleman of honourable place at Aix in France, where for his industrie & exactnesse in all parts of Antiquity, especially in this, may deserve the Elogy which Plinie gives to Hipparchus, that he was In omni diligentia mirus. And surely had he lived to have finished what in his letters, which I have seene in french, in ye hands of Monsieur Buchard a learned man, he intended it would have been in vaine for any man to have written after him.'
