He had a curious bend and walk, which made him seem a little like a dog walking on his hind legs.

He was very fond of the boys and they of him.

He made full allowance for the exuberance of youth.
Two careless students who were driving in a sleigh ran against him in the street and knocked him over and injured him severely.

What awful and mysterious meaning the words "by Jingo" had for the old Spanish gentleman we never could discover.
