This monograph contains studies on peripheral circulation in normal limbs, in the limbs of those suffering from peripheral vascular disease, from peripheral nerve injuries or from exposure to cold. The author reviews the evolution of knowledge in this field and builds his own observations on this foundation. Most valuable are his observations on the vascular changes after peripheral nerve injuries. These were made in a peripheral nerve injury center which contained about 350 patients. Equally lucid and instructive are the studies on immersion limb. This is a logical, lucidly written book, excellently printed and illustrated. It is representative of the best type of clinical physiology, in which Sir Thomas Lewis excelled. For residents and young vascular surgeons there could be no better instruction in fundamental knowledge or stimulus for future research.
