August 9, 1916 Dr. Wm. J. Holland Care Carnegie Museum, Pittsburgh, Pa. Skull, or part, found as expected in undoubted association with skeleton of supposed Apatosaurus. Number 240. One of most important discoveries yet made. Skull probably not all articulated; teeth of pattern figured by Marsh as Brontosaurus and Morosaurs. Will write more fully. Everything is good shape here.
