In the 9 years since the last colloquium on lateral loading at the Institution there has been a great deal of published material, much of it reviews or theoretical conjecture, but some useful experimental work at various locations. Important theoretical contributions have come from L. R. Baker, who has developed a theory which relates to the strength of individual joints, and Cajdert in Sweden.
