and many manufacturers’ gifts have been introduced, so that 
the balance of the series is destroyed. A readable as well 
as exhaustive handbook, descriptive of the collection, is for sale 
by the attendant. 
The paleontological collection is one of the largest in Europe. 
It is especially rich in mammals, reptiles, and fishes of North 
America. It is divided into three collections. In the first 
the fossils are arranged according to their biological order; in 
the second, according to their order in time; while the third is 
a local collection of fossils of Bavaria. Wall and floor cases of 
hard wood are used; the former of the usual type, the latter, 
desk cases with tops of a low slope. The smaller specimens 
are mounted on cardboard, the larger on bases of plaster or 
wooden blocks painted white. Most of the incomplete skele- 
tons are restored, but a few, especially fishes and reptiles, are 
mounted upon wire frames, on which each bone has its proper 
place. While nothing especially novel in methods of installa- 
tion was noted, the extent and variety of the material in this 
collection are such as to make it especially worthy of study. 
Among many specimens of great interest are a nearly com- 
plete skeleton of Rhinoceros tichorinus, found in a moraine 
near Ascham in Innthal; a complete skeleton of 77/anotherium 
trigonoceras, and two skulls of the same genus; complete skel- 
etons of the cave bear, of Rhinoceros and Hipparion, of Dinornis, 
and of many smaller species. Remains of an Ichthyosaurus 
from Boll, Wiirtemberg, show two young in the womb of their 
mother, thus giving proof of the viviparous character of the 
species. Other specimens show clearly the heterocercal tail. 
The fossils from the Solenhofen beds are superior in quality 
and quantity, some being remarkably vivid in their representa- 
tion of ancient life. On one specimen may be seen tracks of a 
Limulus made for a short distance, and at the end the animal 
itself. Another specimen shows the trail of a mollusk made on 
the sand, ending with the mollusk itself,

lation employed in this museum have been so fully described 
by Dr. Hovey that little need be added. As in all other
