SURGICAL APPLICATIONS OF THERAPEUTIC VENOUS OBSTRUCTION

It is remarkable that a process so apparent as the circulation of the blood could have remained undiscovered through so many centuries during which there was an accumulation of knowledge of other more complex phenomena. If one only contemplates the vast number of opportunities which were presented for the discovery of the circulation of the blood and recalls the simplicity of the experiments of William Harvey, one is amazed that this discovery should have been deferred so long.
