able matter, which being thrown back upon 

 the lungs, they are so overloaded as to be 

 rendered incapable ofperforming their func- 

 tions, and passing it into the circulation: 

 inflammation is then produced ; which, ac- 

 cordino; to the nature of the case and cer- 

 tainty of circumstances, must terminate in 

 suffocation, if suffered long to continue its 

 progress, without effectual attempts to re- 

 lieve Nature from the burthen she has ac- 

 cumulated. This disease may also be pro- 

 duced by violent exercise upon the turf^ or 

 exertion in the Jield, when the increased ra- 

 pidity of circulation (by the action of the 

 solids upon their contents), propels the blood 

 to the smaller passages with so great a de- 

 gree of velocity as not only to produce im- 

 mediate inflammation, but sometimes to 

 rupture some of the finer vessels, from which 

 BROKEN WIND or CONSUMPTION frequently 

 proceeds. 



A sufficient quantity of blood must he m^ 

 sianfli/ taken away, to unload the vessels as 

 much as the strength will bear. After this 

 operation, have ready some bran and very 

 sweet hay cut small, and scalded together.
