upon the others as I should like to have done, and, in concluding, 
may I urge upon you very briefly the need for a wider study of natural 
history by each individual ? The specialist who is content to limit 
his knowledge of Nature’s works solely to one narrow branch of them, 
cannot, to my mind, be called a naturalist in the true sense of the word. 
Spcialism is undoubtedly necessary, hut it can be carried too far. The 
ideal naturalist, I think, should possess at least a rudimentary knowledge 
of every department of zoology and botany, in addition to devoting 
his special attention to one of them. Nature is an entity, and I feel 
strongly that if her student is to drink her deepest delights, and to 
appreciate to the full the charm of the association of animals and 
plants, it is as an entity that he must study her.
