MARINE BIOLOGICAL STATION ON PUFFIN ISLAND. 53 
branchs—almost defy description; they must be seen to 
be appreciated. 
It is proposed to divide the littoral zone of the island 
into several regions or sub-zones, and investigate the 
Fauna and Flora of each separately, so as to determine 
their characteristic animals and sea-weeds, and the relative 
capacities the different species possess for withstanding 
exposure to air and sunshine. At the northern end of the 
island, close to the Biological Station, some of the larger 
rock-pools might be easily converted into natural aquaria, 
enclosed with wire netting, so as to exclude stones and 
sea-weed and prevent the animals placed in the pools from 
escaping at high tide. The water in these aquaria would 
be renewed at every tide, and the animals would be under 
natural conditions and yet could be easily watched, and 
caught when necessary for closer examination. Many of 
the Zoophytes and Polyzoa seem to adhere in greater 
numbers and grow to a larger size on fragments of water- 
logged wood from wrecks than on the stones. Such pieces 
of wood, as well as other suitable substances, and also 
various glass vessels could be readily suspended in these 
rock-pool aquaria, and so be available when required 
for examination. ‘These and various other methods for 
facilitating the study of the shore Fauna we intend to 
carry out during the coming summer. 
The following biologists have worked at the station 
since its establishment in the beginning of June, 1887 :—
