We have to thank the Director of Medical Services, Kenya, for pennission to publish this paper and for the help and facilities he has given us in this work. We are grateful to Dr. D. M. Blomfield, Acting Provincial Medical Officer, Coast Province, for his help in the survey in his province. We are especially grateful to Dr. D. H. Mackay, Provincial Medical Officer, Nyanza, and to Dr. H. J. S. Coldham for making it possible for us to examine many hundreds of inhabitants of the Kisumu area, including babies in arms. Without their help much of this work would have been impossible. To Mr. S.
