pleura of the horse, but usually in connection with generalized 

 carcinoma (Langeron, Bean, Hutyra, Gramlich, etc.) Baillet 

 mentions a case in which it weighed 7 lbs. , the mass lying in 

 the division of the bronchi, and leading to the compression pf 

 vessels and nerves in that vicinity. In cattle, Lucet cites cases 

 in the bronchial glands and mediastinum. In dogs, Kitt notes 

 the existence of carcinomata, of a size of from a millet seed to a 

 pea scattered along the bronchial mucosa, and obstructing the 

 bronchioles. This was in a generalized case. Kitt notes a case 

 in the cat. 



Endothelioma. Miliary neoplasms of the pleural epithelium 

 in the horse are recorded by Morot, extending, even into the 

 lung substance. Hutyra quotes a case in the dog, in which the 

 neoplasms took the form of papilloma two thirds of an inch long. 



Epithelioma. These have been found in two cases in the 

 lung of the ^(?rj^ (Nocard, Schiitz), and more frequently upon 

 the pleura and pericardium but also in the bronchial and thyroid 

 glands (Schindelka, Weber, Barrie). They form in clusters 

 which project from pulmonic and parietal pleurae like tubercles. 

 In cattle they have been found in the lung, generally in connec- 

 tion with an epithelioma of the larynx (Kolb), and in sheep in 

 the lung (Besnoit). They were small hard miliary granules" 

 which could easily be felt by passing the hand over the surface 

 of the lung. In dogs they are found in the substance of the lung 

 and on pleura and pericardium, sometimes along with similar 

 formations in the peritoneum (Montana, Cadeac, I/ienaux). 



Adenoma, Lymphadenoma. Lymphadenoma has been 

 found in the horse's lung in the form of small nodules (I^aulanie, 

 Montane), and Adenoma in the papillary form in cattle (Eber). 



Chondroma. One case in the lung of a horse is reported by 

 Schmidt, the diseased organ weighing 62 lbs. It is described as 

 a chondro-adenoma. Other cases affected the costal pleura. In 

 cattle, Weltzer records a case of chondroma growing on the carti- 

 lage of the bronchus and completely blocking the passage. It 

 was very solid and hard, and covered by a fibrous sac. In the 

 dog, Nocard and Cadeac narrate the presence, in different cases, of 

 multiple chondroma of the lung, a single tumor in one case weigh- 

 ing 1 1 lbs. and extending through the diaphragm into the abdo- 

 men. On section it showed a yellow, nearly homogeneous surface, 

 with haemorrhagic areas.
