Audio history of the psycograph, automated phrenology machine

 Psycograph Psyco-0 Seen here is the Psycograph, an automated phrenology device from the early 1900s. Of course, phrenology was the idea that you could glean great knowledge about someone's personality based on the shape of their skull. (More Psycograph ad images scanned by John Karp are here.) Over at MindHacks, Vaughan points to this fun audio documentary on the Psycograph, from the podcast series This Week in the History of Psychology.
