"a bath-chair arrived and with not a little difficulty, my father was transported into the house"

The bath-chair, invented in Bath in the eighteenth century, was a means of transporting an invalid.  It was a chair mounted on a chassis, with wheels resembling those of a pram. It usually had a folding hood in case of rain, with a built-in glass window. The first bath-chairs were pulled along by a small horse or donkey, but they were later redesigned so as to be pushed by a helper or propelled by the invalid themselves.
