§ 351. Characterization. Contagious pleuro-pneu- 

 monia of cattle is a specific epizootic disease which affects 

 bovine animals and from which other species are exempt. 

 When the disease results from exposure in the usual manner, 

 it is characterized by an inflammation of the lungs and pleurae, 

 which is generally extensive and which has a tendency to 

 invade portions of these organs not primarilj' affected and to 

 cause death of the diseased portion of the lung.

 the first time in 1693, and that its earliest appearance as an 

 epizootic was in 17 13 and 1714, when it prevailed chiefly in 

 Switzerland and the neighboring countries of Wurtemberg, 

 Baden and Alsace. There are detailed reports of its occur- 

 rence from the year 1743. In 1773, Haller published an essay 

 on this disease, which was raging severely at that time. He 

 described the symptoms, anatomical characters and protective 

 measures laid down at that time by the sanitary police. In 

 i735> the disease appeared in England and in 1765 in France. 

 From 1790 it spread over the whole of Germany, France and
