forms, the whole of the selection and grouping of the collections being 

 subordinated entirely to securing a representation, as nearly normal as 

 possible, under the limitation of space and conditions of the material, 

 of the characteristic assemblages of marine animals and plants. 

 Numerous tanks of considerable size contain displays of faunal types, 

 in alcohol or formalin, in natural groupings and environmental effects. 

 Dried collections and the taxidermist's art are also used in larger 

 exhibits, as, for example, in a most excellent portrayal of a coral reef 

 from the Red Sea. Ten small " alcoholaria " give vivid pictures with 

 much of the original color preserved, of the minor types of faunal 

 assemblages about a coral reef, such as the sea urchins and sea roses 

 (Crambactis) with symbiotic fish (Amphiprion) ; giant mussels (Tri- 

 dacna), corals and parrot fish; the madrepore area; the rock fauna; the 

 regions of dying and of dead corals and the plant life of coral reefs. 

 In like spirit and perfection of technique are displayed the fauna of 

 the Antarctic icebergs, the sponge beds of the iEgean Sea, the fishing 

 grounds off Helgoland, the pelagic world, the sandy grounds, the rock 

 pools, oyster beds, limestone cliffs and the fishing banks of the 

 North Sea. 



The ecological interrelations of the marine fauna are suggested by 

 exhibits of the food of well-known fish. The economic values and uses 

 of the products of the sea are concretely illustrated in striking manner 

 by transparencies, and by exhibits of the crude materials and various
