Fairholt appears to have pasted a note from Evans with a coin sketch and findspot details on the front pastedown. On the first side of the first free endpaper, he tipped-in a four-page letter from Evans dated 1860, and onto that another two-page letter from the same year.

These additions give some idea of the working relationship between Evans and Fairholt. Evans mentions the difficulty of obtaining images of coins. This caused delays in completing the work. Fairholt had to cut the images into wood, so every image had to be secured before a plate could be cut. There was no possibility of inserting a coin after the cutting was done. If the images spilled over onto the next plate, delays in cutting that plate would occur. One can see Evans instructing Fairholt to cut parts of a plate, but then to stop and see if a promised image was forthcoming. It was a far cry from today's electronic methods in which images can easily be moved around, inserted and sized to fit a space.

The letters also give some appreciation for the friendship between Evans and Fairholt, with Evans inquiring about Fairholt's health and giving advice about medicines and cures. Fairholt would succumb to tuberculosis in 1866. He did not make any annotations in the book Evans gave him.

The bronze coin sketched by Evans in the note appears on Fairholt's plate G as number 12. It was deleted from Mack's 1953 catalogue and subsequent writers have not firmly restored it to the British series. Symonds 1990b lists another example (number 5 in the 1990 article), but is uncertain whether it's British or Gaulish. Hobbs 1996 includes it as number 402 on plate 17 as "Early Uninscribed Bronze" but without further speculation about its likely origin. The type needs further research.
