low, often never exceeding 102 Fahr. ; the face frequently 

 becomes suddenly and greatly swollen, and sometimes the 

 whole body is affected in the same way. In certain cases, a 

 peculiar congestion of the eyes has been observed. In general, 

 many of the symptoms in this stage resemble those of typhoid 

 fever. 



In very severe cases the patient is unable to use the mus- 

 cles or move the limbs without the most intense agony, and 

 filially is obliged to lie passively, flat upon the back, with the 

 arms and legs somewhat bent, in the position that gives the 

 least pain ; and later the limbs are rigidly stretched out, some- 

 what apart, the body stiff, and the muscular system in a state 

 of more or less complete paralysis. Children generally lie 

 on the side, with the body bent and the legs drawn up. The 

 jaws are sometimes closed as in lock-jaw. The breathing is 

 difficult, shallow, and rapid. The lungs are often affected, 

 and frequently, also, the heart ; and many secondary diseases 

 are liable to ensue. 



The most that can be done in this stage of the disease by 

 the physician relates to the relief of special symptoms and 

 secondary diseases, and sustaining the strength of the system 

 until nature may in time effect a cure. Most experimental 

 animals die in this stage, and human patients, also, frequently 

 perish even during the early part of this period. 



Third. In case the patient survives the two first stages, the 

 inflammation gradually ceases, breathing becomes more 

 natural, and recovery generally commences, but in very severe 

 cases the muscles and other organs have been so much in- 

 jured as not to perform their proper functions, and general de- 

 bility often results, ending in a kind of consumption that finally 

 proves fatal. In many cases of recovery, lameness lasts for 

 several months. In many cases, however, the final recovery 

 is complete and may be followed by robust health, although 

 tens of thousands of living worms may be still enclosed in 

 the capsules in the muscles. 



From this it is obvious that a hog may be fat and appear in 

 every respect healthy, and yet his flesh may contain such im- 

 mense numbers of the parasites as to be capable of killing a
