Award of Wellcome Fellowship for Veterinary Research IT is announced by the Animal Health Trust that a Wellcome Fellowship for Veterinary Research has been awarded to Mr. S. V. Boyden, B.Sc., M.R.C.V.S. Mr. Boyden, who is a native of Surrey, lives at " Dunster," Tadorne Road, Tadworth, Surrey. He qualified from th e Royal Veterinary College in 1947, was awarded a Research Training Scholarship of the Animal Health Trust, and proceeded to Jesus College, Cambridge. He spent his first year attending the Part II Classes in Pathology, and since then has been carrying out research under Professor Beveridge at the Institute of Animal Pathology. He has been studying the problem of bacterial hremagglutination, and has obtained important results using mallein. With the Research Fellowship he hopes to continue his work, extending it to a number of germs, including bacteria and viruses, causing animal disease. This problem, which is a new one, and which is bringing to light many important facts in the realm of human pathology, should prove equally important in the further study of animal disease.
