On finding that I was to share in the tribute which we are bringing to Sir George Macdonald, I vowed, as do those who mean to give of their best, the first thing that should meet me on my way home.

The first subject that met me on my next appearance at the British Museum was the question of Roman coins found in Britain, and I felt, as Jephthah might have done if, instead of his daughter, his pet mongrel had come out to meet him: was the offering good enough ?
