MARINE BIOLOGICAL STATION AT PORT ERIN. 49 



organisms — both plants and animals — which serve as food, 

 act as enemies, or influence their neighbours in other more 

 obscure and subtle ways difficult to determine. Edward 

 Forbes wrote long ago, " Geology and Zoology will gain 

 as much by inquiring how our marine animals are associ- 

 ated together as by investigating genera and species, 

 though the former subject has as yet been but little 

 attended to in comparison with the latter." Things are a 

 little better now. The teachings of Darwin in regard to 

 the inter-relations of species have told upon the work of 

 the last quarter of a century, but we still require much 

 accurate knowledge in regard to the factors which limit 

 the existence of a species, and I trust that we may be able 

 to do something at the Port Erin Biological Station 

 towards supplying this want.
