young in a pouch, until able to sMft for themselves. Finally 
the Monotremes of Australia, the Duck-billed Platypus, and 
the Echidna, at the bottom of case 98, differ still more from the 
ordinary members of this class, inasmuch as they do not bring 
forth their young alive, but lay eggs. 
Second Flooe. 
The Osteological Gallery is devoted to the skeletons and Skeletons and 
skulls of Mammalia, the arrangement of which corresponds, as Mammals, 
far as practicable, with that of the stuffed specimens. The series 
commences (on the left hand on entering) with a male and female 
human skeleton, followed by a selection of skulls, showing the 
different modifications of the cranial and facial bones in the 
various races of Mankind. Among these is the skeleton of a full- 
grown Akka, only four feet high, which appears to be the usual 
size of this pygmy tribe of i^egroes from Central Africa. The next 
wall-case contains several skeletons of man-like Apes, the Orang- 
Outang, Gorilla and Chimpanzee, with the principal forms of the 
other Monkeys and Lemurs. In cases 4-8 numerous representa- 
tives of the Carnivorous and Eodent Mammalia are shown, the re- 
mainder of the cases of this side of the gallery being devoted to 
the exhibition of skulls of the larger Ungulata, viz., the Elephants, 
Ehinoceroses and Horses. Of the first many skulls are exhibited, 
some in section showing the extraordinary modification of the 
skull in adaptation to the support of the heavy tusks and power- 
ful trunk. The series of elephants is continued in the pavilion 
at the end of the gallery, where skulls and skeletons of the 
African and Indian elephants are exhibited, among them a 
skeleton of a very large tuskless elephant or Mooknah. 
In the pavilion are also placed skeletons of the Sirenia or 
Sea-Cows, aquatic animals more nearly allied to the Ungulates 
than to the Whales, with which they were associated in former 
times. Stuffed examples of these animals have also been 
placed here for want of space in the Mammalian Gallery. 
The majority of the cases on the right hand of the gallery 
are occupied by the Euminant Ungulata, such as the Camels, 
Oxen, Antelopes, Sheep, Goats and Deer ; cases 23 and 24 con- 
taining some additional skeletons and skulls of Sirenia, the
