MAMMALS OF THE WORLD 



Continuing east from the hall where the apea and monkeys are, we 

 pass the elevators, to enter the hall of the Southeast Wing, devoted mainly 

 to a series of exhibits illustrating the characters of mammals, their 



principal groups, or orders, the main subdivisions of these, known ae 

 families, and various interesting peculiarities of habits and structure. 

 Each family is, so far as possible, represented by a mounted specimen 



and a skeleton. Walking around the room from left to righl <>nr passes 

 from the egg-laying Platypus ;<> man. represented by the figure of an 



Australian native, armed with the characteristic boomerang. Incident- 

 ally one sees among other things the modification- of form and structure 

 for various modes of locomotion, notices the superiority in brain of 

 mammals over other vertebrates, learns that animals that outwardly 

 look alike may be very distantly related, sees illustrations of albinism 

 and melanism, and is shown how the coat of the hare changes from brown 

 to wdiite. 



A small case contains rare or interesting mammals. 



Of special note are the skeleton of Jumbo, the largest elephant ever 

 brought to this country, and the skull of the largest elephant shot by a 

 woman. The latter was killed near Mt. Kenia by Mis. Akeley and has 

 tusks weighing respectively 112 and 115 pounds, 



Above the cases is a frieze representing marine scenes, which serves 

 as a background for groups of porpoises, dolphins and other small mem- 

 bers of the whale family. The most striking object in the hall is the 

 life-size model of a sulphur-bottom whale, seventy-nine feet in length. 

 Model of The original of this specimen was captured in New- 



Sulphur- foundland, and the model is accurately reproduced from 



bottom careful measurements. This huge creature is not only 



Whale foe largest of living animals, but, so far as we know, 



the largest animal that has ever lived; a specimen of this size weighs 

 from sixty to seventy tons, twice as much as Brontosanrus. Although 

 wdiales and porpoises live in the water, they are not fishes, but arc warm- 

 blooded and breathe by means of lungs, not gills. The whale must come 

 to the surface to breathe and the so-called "spouting" is merely the 

 result of the warm air being expelled from the lungs when he breathes. 

 A whale does not spout water, as is commonly supposed. Models to scale 

 of the other wdialebone wdiales, and the toothed sperm whale, and repro- 

 ductions of smaller wdiales and porpoises are hung near for comparison, 

 among them one of the fierce Killer, the worst enemy of the larger whale-
