The Heliotype Process. (Heliotype Company, Limited.)—This book gives a description

of a well-known process for reproducing works of art, &e., and illustrates it appropriately with a number of specimens representing the results of the process. There are copies of artistic work of all kind; paintings, pen-and-ink sketches, chalk drawings, &c.; of engineer's plans, maps, &c., together with scenes taken from nature. All of them seem excellent.
