Comments: "A thoroughly reliable guide to the art of voice throwing and vocal mimicry by an entirely novel system of graded exercises." Warning, there are a few racially insensitive entries. Reprinted through the years. I'm not sure if the later reprints include the full contents of the original, as they only have about 125 pages or so vs. the 155 pages of the original.
