PNEUMONIA. 487 



the tubal murmur was still heard. The pulse became stronger ; the 

 patient was brighter than on the previous days, and ate a little hay. 



On the ist February the condition remained stationary. Morning 

 temperature 397° C. ; respiration 20°. The dulness and bronchial 

 murmur remained. There were signs of cardiac weakness. 



On the 2nd the patient appeared greatly depressed. It was feeble 

 and tottered on its legs, so that it had to lean for support against the 

 side of the stall. Temperature 39'2° C. ; respiration ^^ ; pulse 

 very rapid and small. Dulness was limited to the lower third of the 

 chest ; the tubal murmur was weaker. The animal refused all food, 

 including even milk. During the night it lay down on its side. 



Next day it was found standing up eating some hay. It showed a 

 little opposition when we attempted to auscultate the chest. The zone 

 of dulness was limited to the lower half of the right lung ; above this 

 the crepitant rale peculiar to resolution could be detected. Tempe- 

 rature 38*7° C. ; respiration 15 : pulse 80. 



On the 4th the temperature was 38*2^ C, respiration 12, and pulse 

 64 ; the pulse still remained feeble. The animal received three injec- 

 tions of eighty minims of ether and one drachm of digitalis in electuar}^ 



On the 5th and 6th the temperature and respiration became normal ; 

 the pulse was still 60, but fairly good. 



The last symptoms disappeared during the following days. On the 

 nth February the animal had recovered. 



183. A six-year-old entire horse entered hospital March loth, i8gg, 

 after an illness of two days. Had come from a stable in which 

 contagious pneumonia existed. 



State on Examination. — The animal was depressed, showed rigors, 

 and hung back from the manger. The mouth was hot, the skin cold, 

 and the mucous membranes markedly injected. Respiration 24 ; 

 puise 75 ; temperature 40*5° C. The cough was strong and dry. There 

 was little discharge. Pressure over the intercostal spaces caused pain. 

 Respiration was irregular, expiration being slow and double. The 

 lower quarter of the right lung was partially dull on percussion, but on 

 auscultation the vesicular murmur was found to have disappeared ; 

 during expiration a few moist crepitant rales could be heard. In the 

 upper part of the right, and over the entire area of the left lung the 

 vesicular murmur was exaggerated. The pulse was feeble ; the heart- 

 sounds were strong and rhythmical, but at varying intervals a pause, 

 equal in duration to a complete heart cycle, was noted. 



Treatment. — ^Mustard applications to the chest ; sulphate and bicar- 

 bonate of soda ; alcohol. The mustard plaster produced a large 

 swelling within four hours of application. The rectal temperature was 

 39-8° C. Appetite was preserved ; the patient took several quantities 

 of gruel and 8 quarts of milk. There was no noteworthy change 

 during the evening. Temperature 40*3° C. 



On the nth the animal was more depressed than on the previous 

 evening. The conjuctiva was deep yellow. Respiration 22 ; pulse 76 ; 

 temperature 40-1° C. Inspiration was short, expiration prolonged and 

 double. The lower part of the right lung was dull, and on ausculta-
