Excerpt from State Control of Tuberculosis TO successfully control a disease it is necessary to know how it is caused. For a century or more, many acute Observers have been convinced Of the contagious character Of tuberculosis. Experiments were long ago undertaken to prove its communicability, and some Of them, particularly those Of Villemin, were successful. The intelligent medical world was not, therefore, un prepared for the discoveries Of Koch. By him was discovered the essential factor in the causation Of the disease. His experiments were a complete demon stration that the disease we are considering is due to the action upon the tissues Of the tubercle bacillus. The bacillus is the cause Of the disease. Scores of competent Observers at once attempted to prove or disprove Koch's views. This is the proper fate Of every important discovery and Of every alluring error. Eighteen years have passed, and no person able to judge denies the causative relation Of the bacillus to the disease. The definition Of the disease is made by the facts. Whatever abnormal condition is produced in the tissues by the bacillus is tuberculosis. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
