SYMPTOMS OF THE DISEASE. 15 



quent ; loss of appetite ; in cows, the almost entire suspension 

 of milk secretion ; head drooping when standing, and when 

 lying the nose thrust hard on the ground — sometimes turned 

 back over the side, and pressed against it ; the ears drooping, 

 back arched, flank hollow, hind legs drawn up under the body ; 

 frequent knuckling over of the hind fetlocks ; disposed to lie 

 down and get up again, which it does with difficulty ; when 

 made to move, it is often with a staggering, unsteady gait. 

 Occasionally an animal appears delirious, at other times sleepy ; 

 the coat becomes rough ; at times, frequent twitching of the mus- 

 cles appears about the shoulders and other parts of the body. 



POST MORTEM APPEARANCES. 



The post mortem appearances are blood-staining petechias, or 

 ecchymosis of the internal membrane of the body, especially in 

 and around the heart, sometimes, but rarely, over the lungs, in 

 a few cases over the lining membrane of the belly, and very 

 generally over the mucous lining of the stomach and intestines. 

 The respiratory passages are found healthy — the lungs some- 

 times very partially congested, and were commonly blown up 

 with air between their lobules, constituting what is known in 

 medicine as interlobular emphysema. 



The three first stomachs are usually healthy, and especially 

 the third, which has been described as impacted, does not differ 

 materially, in the great majority of cases, from that state which 

 we are so well accustomed to see in healthy cattle when slaugh- 

 tered ; the fourth stomach is intensely congested at its upper 

 end, less so near the intestines, but all over may be seen, in 

 some cases, spots of blood extravasation, in others grayish, 

 granular deposits, and in almost all erosions of the lining 

 membrane. 



The intestines are, with rare exceptions, congested and blood 

 stained, more or less, throughout their whole extent. Tlie liver, 

 often congested, is not materially implicated in the disease. 

 The gall bladder has its coats sometimes thickened by a gelat- 

 inous-looking fluid, and its contents are dark and viscid. Its 

 internal coat is sometimes congested. The spleen is always 

 enlarged. It should weigh from one to one and one-half pounds, 

 but it is found in this disease as high as five, six, and even eight 

 pounds in weight. It is dark colored, and its structure broken up.
