At this point, I shall explain once for all a system which will be continued throughout this book. The persons, places, and exhibits mentioned or referred to in the text are invariably definite and concrete. A complete register of them has been made, each item being lettered and numbered. The sign X 2 in the present instance enables the writer promptly to put his finger on the name, address, etc., of the person designated. This is equally true of all future references similarly indicated.
