'Life Under Water'
E. B. WORTHINGTON , Ph.D.
These talks hitherto have dealt with life on the earth, underground, and in the air, and it is the turn of the fish to come under the microscope this evening. A deliberately chosen term, for Dr. Worthington observes not only with his eyes, but with microscope and scalpel. Post-mortem inquiry into the feeding habits of the fish inhabiting the Vyrnwy Lake, constructed forty-five years ago. has revealed interesting differences between the same species of fish frequenting different parts of the lake. He will discuss this this evening.
To Dr. Worthington fish have the same beauty and interest as animals-perhaps more interest because so little is known about them. He is Demonstrator in the Department of Zoology in Cambridge University and had a distinguished career there. In addition he has undertaken several fishing surveys of the African lakes, and he was awarded the Gill Memorial by the Royal Geographical Society in 1932. In that year he gave a broadcast talk ' Crocodile Island '.
