but on the contrary remained indisposed, re-

at each movement grunted with agony. The 
respirations at first only slightly accelerated 
became gradually faster during the succeeding 
three weeks, at which time several gallons of 
exudate were aspirated from the right side of 
the thorax. The patient’s condition became
