Symptoms. If the chronic peri- carditis is limited to a few partial adhesions, it remains unnoticed 5 but when it is more marked it offers certain signs of acute pericarditis, such as partial dulness of the car- diac area, which is more extensive than usual, disappearance of the cardiac shock, weakening of the sounds, feebleness of the pulse, very marked venous pulse, moderate stasis, extremely rapid and aggra- vated dyspnoea when the animal is forced to walk, threatened asphyxia if exercise is prolonged, and com- plete asystole. All these symptoms are due to the existence of adhesions between the heart and pericardium, which, by destroying the interpericardial space, interfere with diastole while preventing regular systole. Sudden death is a frequent consequence. The diagnosis of chronic pericarditis is very difficult. The prognosis is extremely grave, and we do not possess any means of dealing with the condition. PSEUDO-PERICARDITIS. Under this title we purpose grouping a certain number of pathological accidents due to different causes, but manifesting themselves by identical symptoms, which symptoms offer so marked a resemblance to those of pericarditis produced by foreign bodies as to suggest the presence of that.
