Britches

Britches was the name given by researchers to a Stump-tailed Macaque monkey who was born into a breeding colony at the University of California, Riverside in March 1985. He was removed from his mother at birth and had his eyelids sewn shut as part of a three-year maternal and sensory-deprivation study involving 24 infant monkeys.
The study was conducted by David H. Warren.
