Lavery Electric Phrenometer



The Lavery Electric Phrenometer is an automated phrenological measuring device, invented and patented by Henry C. Lavery, which was the basis for the more well-known Psychograph of later decades. The device operates by automatically taking measurements of several areas of the subject's head and producing a print-out record of the readings taken, specifically functioning as a "phrenometer for measuring the faculties of intelligence of the head, and hence determining the size and character of the brain contained therein."
