"A curious and intesesting work. Mr. Dircks' chief purpose was to collect together all the materials requisite to form a record of what has been done, or attempted rather, in this curious branch of quasi science, and most instructive in one sense it is. Mr. Dircks' volume is well worth looking into; it contains a vast deal of entertaining matter." - Builder.
