As the unnatural compression of the blood in the renal vessels, thus artificially produced, gave rise to phenomena identical with those constituting the primary effects of inflammation, and as the kidney seemed to present greater facilities for an experimental investigation of that important subject than any other organ of the body, I was induced to
