The mechanisms by which meteorological and social cycles influence reproductive behavior remain unclear. However, historical data from the 16th century suggests that marriages in November led to conceptions within two months, resulting in births around September. This bimodal pattern may be due to marriage customs and the significance of first births in societies with high adult mortality. The study was supported by the Sigma Xi Society and the Wenner-Gren Foundation. The author thanks Prof. G. E. Hutchinson for his support. In nuclear physics, Mr. John Clemow has been appointed head of the Nuclear Physics Division of the Science Research Council. He has a background in engineering and mathematics, served in the Royal Artillery, and is a member of several professional societies. Dr. Morton has been appointed chair of applied mathematics at Monash University. He has a strong background in physics and mathematics, and his research interests include geophysical fluid dynamics, fluid mechanics, and related topics. In education, the Department for educational research allocated £250,000 for projects in 1965–66, with £55,000 going to the National Foundation for Educational Research. Local authorities, charitable foundations, and universities also supported research. The Directorate of Research and Information advised on research policy, commissioned research, and provided technical information. It had a budget of £165,000 for 1965–66, with £42,000 for overheads. The University Building Programme included 25% of the 1965–66 building plan starting in 1966–67. The £120 million plan for four years was not affected by revised deferment arrangements.The mechanisms by which meteorological and social cycles influence reproductive behavior remain unclear.
