Mouth with large sublingual cyst

Watercolour drawing of the inside of the mouth of a man who had a large sublingual cyst, displacing the tongue upwards on to the roof of the mouth. From a man aged 46, who stated that the cyst had existed all his life. It caused no inconvenience beyond a slight impediment in his speech, and he had always refused to undergo any operation for its removal. At the time the drawing was made he was suffering from advanced phthisis.
