Phil the gorilla, as impressive in death as he was in life, still draws crowds at the St. Louis Zoo, where the mounted figure is on display in the Old Elephant House, next door to the ape house where he lived before his death last December. The massive figure, standing erect in a characteristic pose, holds the fascinated gaze of three young visitors, Karen, 3, and Debra Hartman, 5, daughters of Mr. and Mrs. Lyode Hartman, 943 St. Charles st., St. Charles, Mo., and Pam Karrenbrock, 7, daughter of Mr. and Mrs. Mel Karrenbrock, Wentzville, Mo.
