THE STOCK OWNER S ADVISER. 



surgeon perfonn the operation of paracentesis thoracis, or tap- 

 ping. The fluid should be removed by the trocar and canula, 

 which should be inserted in the space between the eighth and 

 ninth rib. 



CONGESTION OF THE LUNGS. 



This gives rise to a partial or complete arrest of pulmonary 

 circulation. The blood is detained in the parts, causing func- 

 tional derangement of the lungs. It is a forerunner of pneu- 

 monia. 



Cause. — The disease is caused by standing idle during the bad 

 winter months and being put to severe exertion all of a sudden 



when spring opens us. It 

 may result from working a 

 horse while suffering with 

 other pulmonary affections. 

 It is also produced by ex- 

 posure to rain when over- 

 heated. I saw two cases 

 produced from this cause in 

 a pasture in one night. The 

 colts were turned into the 

 field, where they ran and 

 played for some time. Late 

 J in the night a heavy rain 

 came up, and they con- 

 tracted the disease. I saw 

 them the following even- 

 ing just before their death. 

 Symptqjis. — The animal 

 is observed to shiver; all 

 food is refused; the mouth is hot, the extremities are deathly 

 cold; the pulse beats eighty or ninety per minute. There will be 

 a peculiar flapping of the nostrils, the flanks heave rapidly; the 

 eyes are blood-shot. In some cases there will be a discharge of 

 fi'otliv blood from the nose.
