The University of Hong Kong and its Department of Anatomy have paid me the enormous compliment of continuing to invite me to present research lectures, over the years.

These lectures have included, from time to time, many of the different lines of research upon which I am embarked: biomechanics of bone form and architecture, study of the deficiency of vitamin B12 in monkeys and apes, mathematical, physical and engineering methods in functional anatomy, relationships between morphological and molecular evolution in the primates, and evolution of differences between the sexes.
