This type of vaginal speculum was known as 'Fergusson type', having been invented by Sir William Fergusson (1808-1877), a leading British surgeon who practiced in London in the mid-1800s. Made from glass, this speculum has a mirrored interior which allowed for internal examination by reflected light. Devices such as these were used in the diagnosis and treatment of conditions of the vagina and uterus. This dates from around 1870, England.
