quarry -- the skeleton which is now on exhibition mounted in a standing position in the Hall of Vertebrate Paleontology. Some of the bones of the skeleton have been removed but the greater portion still remains in the rock. So far as splendid preservation of the bones is concerned this specimen seems at present, to take first place. The great interest in this "find" lies in the fact that it gives another hope that a skull may be found in undoubted association with a skeleton of Apatosaurus and settle forever the problem as to what kind of a head this animal possessed. Ten vertebrae of the neck and probably several ribs of a gigantic sauropod Dinosaur have been recovered, with seemingly good prospects of obtaining the remainder of the skeleton. These ten cervicals, as nearly as they can be measured in the rock aggregate 27 feet in length.
