Calliper used to measure head size, London, England, 1886-1927
Not much is known about this instrument. It is thought that it was used by phrenologists to take accurate measurements of the head. Phrenology was a practice based on the belief that personality could be read from the bumps and lumps of someone’s skull (and thus the underlying structure of the brain). Made by Arnold & Sons, surgical instrument makers, the callipers were once owned by the British Phrenological Society. Founded in 1886, the Society closed in 1967.
