of iodine ; each of these methods furnished one case 

 of cure. 



Most of what has been already said respecting 

 the different methods of treatment has reference 

 to the hydatid cysts developed in the abdominal 

 cavity, and especially in the liver ; in such cases the 

 danger of effusion into the peritoneum constitutes 

 the chief difficulty of any operation performed for 

 their removal. Puncture, or simple incision, may be 

 performed when the cysts are united to the abdominal 

 walls by adhesions ; but if there be no adhesions, it 

 will be necessary to leave the canula in the opening 

 after having recourse to puncture, or to gradually 

 destroy the coverings of the tumour, and to produce 

 the formation of adhesions by the appHcation of 

 caustics. 



When the ordinary signs of adhesion, such as 

 tumefaction, redness, &c., are absent, it is difficult to 

 form a correct opinion as to whether any adhesions 

 exist between the cyst and the abdominal parietes. 

 Two methods of determining this question have been 

 suggested. 



In the first, the patient having been placed upon 

 his left side, a line is to be traced with ink along the 

 lower border of the liver or of the tumour ; then, by 

 causing him to repeatedly change his position, and 

 to make deep efforts of respiration, we may observe, 

 if there be no adhesion, variations in the relative 

 situation of the fine traced upon the integument and 

 the position of the edge of the liver, or of the 

 tumour. 



According to the second plan, the patient is to 

 be placed upon the side opposite to that on which
