—I removed a gallstone from a woman yesterday which I think is the largest individual gallstone in the country. If there is a larger one please let me know. The stone weight and measurements are: weight 2½ ounces (70 Gm.); length, 3 inches (7.5 cm.); diameter, 1⅝ inches (4 cm.); circumference, 4½ inches (11.5 cm.).
