Letter from Howard Walter Florey to Simon Rodbard, Chronic Disease Research Institute, Buffalo, New York Sure Rodbard will have interesting meeting on mechanical forces acting on the vessel well - only people he knows of in Britain working on this, are Drs Taylor and McDonald of St Bartholomew's Hospital - Stehbens, in his Department, worked in Sydney on blood flow and possible effects of turbulence on vessel wall - does not know if Stehbens will be returning to Sydney via USA at time of this conference - will ask Stehbens to send reprints. 15 August 1959
