THE DISEASES OF CATTLE. 63 



When the lungs become involved and the disease is passing 

 into the typhoid stage, the symptoms vary and intensify, as the 

 various tissues of the body become secondarily affected. Those 

 that have paid the most attention to the prevailing symptoms, 

 record the following : — 



" The ' lung disease,' combined with typhus, may be divided 

 into three periods. The symptoms of the first period, during 

 which there is no fever, are, — sadness and prostration of 

 strength ; second, drooping head and pendulous ears ; third, eyes 

 fixed without loss either of lustre or of color (in vigorous animals 

 the eyes are often red and fiery, but dry) ; fourth, the skin of 

 the nostrils pale, and the inside of the mouth ' slimy ;' fifth, 

 temperature of the body low, with horns, ears, and feet cool ; 

 sixth, skin dry and tense [stretched], the hair lustreless, rough, 

 and bristly, and erected along the spine ; seventh, breathing 

 difficult. The first period sometimes lasts a fortnight or three 

 weeks ; the second, or feverish period lasts three or four days. 

 The symptoms are those above described, with feverish move- 

 ments. The diseased animal has fits of shivering, considerable 

 exacerbation in the evening, and remission of* fever towards the 

 middle of the day. After the cold, or aguish fits are over, 

 the reaction is much less violent than in other inflammatory 

 complaints. Each paroxysm of fever is accompanied by an 

 acceleration of the respiration, which is audible, and often 

 accompanied by a moaning sound. The weakness and exhaus- 

 tion of the animal are very great ; the temperature of the ears, 

 horns, and legs change continually — now warm and now cold,; 

 the skin is dry and rough, and looks as if dust were strewn on 

 it ; the hair is erect, and the eyes which are opened wide, are 

 projecting, dry, shining, and fixed. The pupil is dilated. The 

 nostrils are covered with a slimy secretion, which the suffering 

 animal removes with its tongue ; the teeth are loose ; the loins 

 are so sensitive that the pressure of the hand cannot be borne 

 without shrinking, and the pain in the chest increases. The 

 animal lies down but seldom, and when it does so, it is on the 

 side on which the lung is affected. If both lungs are diseased,
