Linseed-oil or castor-oi], a sufficient quantity to make

Emphysema of the Lungs. 



This condition of the lungs is caused by a progressive 

 dilatation of the alveoli, and destruction of the septa 

 dividing them, and it is accompanied by an enlargement 

 of the whole organ. Thus, bilateral enlargement of the 

 chest is produced, and also extension of the left lung over 

 the heart. There is expiratory dyspnoea and prolongation 

 of the expiratory sound. Percussion gives rise to a tympa- 

 nitic note. In human beings bronchitis is always associated 

 with this state, and the right ventricle is dilated and hyper- 

 trophied. On the other hand, pneumothorax is never 

 bilateral, and it gives rise to amphoric sounds. 

 Same remedies as for ' Broken Wind.'

 its Meninges).
