There is no real paradox in both bleeding and giving stimulants 

 in such a case, as the essential condition is one of weakness, and 

 if the abstraction of blood has been of use in relieving the 

 clogged heart and lungs, the depression under which these have 

 labored may be still further overcome by agents calculated to 

 rouse their suspended vitality. 



Trasbot strongly recommends large doses of tartar emetic and 

 iodide of potassium to reduce the blood pressue in the lungs, an 

 advice which will be received with hesitation by those who dread 

 the already paretic condition of the heart. His combination of 

 iodide of potassium with digitalis will be more confidently re- 

 sorted to. One drachm of the former may be given with a half 

 drachm of the latter twice daily. 



With the advent of marked fever and other signs of pneumo- 

 nia, the treatment for that disease should be resorted to. 



PUIvMONARY CEDEMA. 



Causes, pneumonia, extra force of right heart or weakness of left, insuffi- 

 ciency of mitral valves, deflection of blood by obstruction in one portion of 

 hing, pressure of tumor on pulmonary veins. Malignant oedema. Malig- 

 nant catarrh. Bright's disease. Anaemia. Parasitism. Symptoms, ab- 

 normal heart sound, or urinary secretion. Parasitism. Percussion shows 

 flat sound auscultation lowered, respiratory murmur, heightened blowing. 

 No crepitation. Expectoration serous. Prognosis grave. Treatment, at- 

 tacks primary disease. Posture. Elimination. Dry capping. Heart 

 tonic. 



A dropsy of the lung tissue may supervene in weak conditions, 

 in the course of inflammatory disease of the lungs ; it may also 

 depend on an imperfect balance in the forces of the right and left 

 heart respectively, which leads to the habitual throwing of blood 

 pres.sure back upon the lungs. Still more frequently the conges- 

 tion and dropsy depends on insufficiency of the mitral valves by 

 reason of which a reflux of blood toward the lungs takes place 

 at each heart-beat. The pressure of tumors on the pulmonary 

 veins may have a similar action. Obstruction of circulation in 

 one portion of lung may cause an extra blood pressure on an ad-
