THE BROOKLYN MUSEUM 



scale model, "Woodland Tragedy," represents two deer 

 with inextricably locked antlers, a realistic interpretation 

 of the facts being indicated by the actual pair of skulls with 

 locked antlers shown on the adjacent wall. This fatal end- 

 ing to an encounter of fighting bucks in the mating season 

 is not uncommon. 



Proceeding eastward, the Hall of Invertebrates (Room 7 

 on plan) is next entered, where the sponges and corals, 

 worms, mollusks, crustaceans and other types of animals 

 lacking a backbone are exhibited. 



The sponges and corals, from all parts of the world, are 

 systematically arranged in wall cases on the west, north and 

 south sides of the hall, and in various floor cases special 

 groupings have been made of sponges and corals of par- 

 ticular beauty or interest or of unusual size. 



Specimens of the Protozoa, or one-celled animals, the sim- 

 plest forms of animal life, are shown in the first floor case 

 on the left (north) side of the hall, by the aid of micro- 

 scopes, and also by enlarged glass models. The sponges 

 are the simplest forms of animals whose bodies consist of 

 more than one cell, for the cells, although arranged in two 

 layers, act each independently. Varieties of lime sponges, 

 glass or silicious sponges and horny sponges are shown, as 

 well as fresh-water, deep-sea and boring sponges, and 

 sponge spicules under the microscope. 



Models of coral, showing the anatomy of the polyps and 

 their relation to one another, are seen in the second floor 

 case on the left, which contains also models of the fresh-
