At this point Parry, who had been sitting silent during the
discussion, probably because of its somewhat abstract character,
suddenly broke in upon it as follows. He had a great fund of optimism
and what is sometimes called common sense, which to me was rather
pleasant and refreshing, though some of the others, and especially
Leslie and Ellis, were apt, I think, to find it irritating. His
present speech was characteristic of his manner.
