gigantic Dinocerata, several hundred in number, Eocene 
mannnals described in his monograph on this group; (4) the 
Ihontotheridfe, huge Miocene mammals, some two hundred 
in number; (5) pterodactyles, or flying dragons, over six hun- 
dred in number; (6) the mosasaurs, or Cretaceous sea- 
serpents, represented by more than fifteen hundred individ- 
uals; (7} a large number of dinosaurian reptiles, some of 
gigantic size. Besides there are various other groups of mam- 
mals, birds and reptiles, most of them including unique speci- 
mens. 
Additional collections comprise extensive series of fossil 
footprints, invertebrate fossils, recent osteology, American 
archeology and ethnology and minerals. 
The main conditions of the gift, which is for the benefit 
of all departments of the University, are that the collections 
shall remain in a fire-proof building and vmder the control of 
Prof. Marsh during his life ; after that under the charge of the 
trustees of the Peabody Museum, and, finally, that type speci- 
Tnens shall not be removed from the museum building. 
From the scientific point of view the value of the collec- 
tions is beyond price, each one containing many specimens 
that can never be duplicated and already are of historical in- 
terest. .Mtogether this is the most important gift to natural 
science that Yale has yet received.
