 Tn rocks of the western states of animals that lived millions of years ago. Their fossil bones are now found firmly imbedded in rock. The | museum has acquired a very large collection through the great energy and liberality of Prof, 0. C. Marsh Some of the largest known land ami mals are represented in this collection, namely. the Thunder saurian (Bron- tosaurus) with length of so feet and a height of Is feet. This animal is so large that the entire skeleton cannot be mounted in this museum; only the hind limbs are shown. A complete skeleton of Claosaurus, another of these large reptiles, e9 feet long and Is feet high, is mounted in the cen ter of the room. This animal usually walked on its hind legs. and was re- lated to the reptiles that made bird like tracks on the ancient red sand stones of the Connecticut valley. Some of these tracks are shown on the walls above the cases. Other interest ing specimens are the horner dino saurs (see the case with Triceratops), one of which, Torosaurus, had the largest head of any land animal; the skull was nearly nine feet long. Pter- anodon, winged reptile, that preyed upon the fishes inhabiting the great inland sea that five million years ago covered much of western America. The largest of all reptiles, Archelon, measuring Is feet across the extended front fiippers, lived in this same sea at later period.
 The horse collection in the table case near the entrance should be seen by all, as here are shown the remains of ancient horses, beginning in forms no larger than fox and having either four or three toes on each foot This series shows all the stages in the de- velopment of the horse family from this many-toed ancestor to the mod ern beautiful and useful animal with but single toe on each foot, the equivalent of the human middle fln- ger. This collection was the especial pride of Prof Marsh.
