Fouls, foul iu the foot, foot rot, is common in cattle walking 

 through mortar-like mini, especially such as is mixed with fine 

 pebbles, sharp cinders, or shaly particles, and can be propagated 

 by contagion, but it is not an acute vesicular disease, self-limited 

 to a course of 15 or 20 days, but may go on indefinitely. It does 

 not pass rapidly through a whole herd, usually spares sheep and 

 swine, and does not extend to the mouth and teats of even the 

 diseased animals. 



Streptococcic cellulitis of the feet and limbs has the same acces- 

 sory causes as fouls, but is propagated by spherical microbes in 

 chain forms. These may find their way into the quick through 

 any mechanical injury, or inflamed or raw surface, but the disease 

 shows much less tendency to primarily attack the skin of the inter- 

 digital arch, and has a special tendency to extend along the lines 

 of the lymph vessels and plexuses, producing abscesses at intervals, 

 not around the coronet alone, but also on the back and front of the 

 pastern and the lateral aspects of the shank. It is not readily 

 inoculable from cattle on sheep and swine. 



Actinomycosis of the tongue produces salivation and may easily 

 be mistaken for aphthous fever. It is, however, a chronic disease, 

 likely to appear in an isolated case only, without affecting other 

 members of the herd. It is unattended by blisters, or disease of 

 teats or feet, and the tongue either presents an extended induration 

 (wooden tongue, holzzunge) or small elevated spots of raw surface 

 having a marked firmness or hardness, and which in microscopic 

 sections show the radiating club shaped cells of the actinomyces. 

 It is unattended by fever, but may show the characteristic hard 

 swellings in the face or jaw bone (lumpy jaw), or elsewhere, and 

 inoculation produces no such prompt effect as in foot and mouth 

 disease. 



SYMPTOMS IX SHEEP AXD GOATS 



In the small ruminants, the disease usually makes a speedy 

 eruption, the incubation or latency being about the same as in 

 cattle. There is considerable apathy and prostration ; when undis- 

 turbed there is a tendency to remain recumbent ; there is an 

 absence or diminution of appetite, and an elevation of the tem- 

 perature (10-i° F.). Some local symptoms appear; it may be in 

 the mouth, with frothing, constant or frequent movement of the
