“Blows Invisible”

Mr. Brograve, of Hamel, near Puckridge in Hertfordshire, when he was a young man, riding in a lane in that county, had a blow given him on his cheek: (or head) he looked back and saw that nobody was near behind him; anon he had such another blow, I have forgot if a third. He turned back, and fell to the study of the law; and was afterwards a Judge. This account I had from Sir John Penruddocke of Compton-Chamberlain, (our neighbour) whose Lady was Judge Brograve’s niece.
