The retention may be due to sjiecial callings, such as working amongst tar, which plugs up the orifices, or we find friction pro- ducing the same effect. That is why boils are so common in the buttocks of an oarsman, or a rider, and that is why we find them around the neck, and the outer aspects of the limbs, where there is the most friction. Carlunutles are again due to inflammation of a grou[) of sebaceous glands, occurring in those whose general health is feeble from some exhausting cause, such as old age or diabetes. Tlie number of orifices seen oozing on a carbuncle, represents the number of sebaceous glands involved in the process. The slough which comes away represents the gland itself and its contents.
