are brought about by medical and surgical treatment. 

 Notwithstanding the vis medieatrix 'natures, coupled 

 with the most approved surgical and therapeutic, 

 treatment, a fatal termination is by no means an un- 

 common result, which may be brought about by a 

 variety of ways. 



Death may take place from the bursting of the 

 hydatids 



Into the peritoneal cavity ; 



Into the pericardium ; 



Into the pleural cavity ; 



Into the lungs, by perforating the diaphragm. 

 Death may take place from sheer exhaustion, the 

 result of prolonged suppuration of the lungs. 



Death may take place from inflammation of the 

 hepatic veins, and pyaemia. 



Death may take place from plugging of the pul- 

 monary artery ; from inflammation and suppuration of 

 the circumference of the sac ; or death may take place 

 from haemorrhage into its interior; and in some cases 

 death takes place from general marasmus, caused by 

 the echinococcus in the course of its growth, gradually 

 compressing the greater portion of the hepatic 

 parenchyma, and interfering with the normal functions 

 of the adjacent organs. 



i iTi MATOLOGY. The early symptoms of the appear- 

 ance of echinococci in the liver are exceedingly 

 obscure, particularly when small or deeply seated ; 

 and it frequently happens that echinococci exist in 

 the liver, grow and degenerate, and are found after 

 death without having exhibited any symptom of their 

 presence during liie. This is no uncommon occurrence.
