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 
finally 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. Jn 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
