EFFUSION. 133 



twelve cups are applied upon the side at once. On no 

 occasion are cups placed upon both sides at the same time. 

 Before they are applied the coat is thickly greased with hog's 

 lard. Ordinarily, the cups are kept on for about half an 

 hour, in the course of which time it often happens that the 

 animal manifests considerable uneasiness, and at length 

 breaks out into a profuse sweat, seemingly from irritation. 

 Mr. F. says, the relief obtained is in most cases too 

 manifest to admit of question. Circular elevations, from 

 effusion, remain in the skin for some time after their appli- 

 cation; and when these have subsided, indented rings are 

 still left where the cups have pressed ; but they do not 

 occasion any destruction of the coat unless the cups be kept 

 on too long. In dangerous cases, three or four applications 

 of them may be required in the course of twenty-four hours. 

 Mr. Simpson, V.S. Southampton, has, at the suggestion 

 of Mr. Chapman, been in the habit of employing as an 

 application to the sides or breast, even in preference to 

 blisters, in cases of pleurisy, two drachms of tartarised 

 antimony dissolved in two ounces of oil of turpentine. By 

 repeating it, he finds he can produce with it ''decided 

 effect, even after blisters have totally failed. '^ 



EFFUSION. 



Should our patient survive the fury of the first attack, 

 and the inflammation so far abate as to come under the 

 denomination of sub-acute, our apprehensions, though 

 allayed on the score of immediate destruction, still remain 

 so long as inflammatory action is going on, impressed as our 

 minds are with the fact of there being but too much reason 

 to dread that, after all, the case will end in effusion. 

 This, as I stated before, is of two kinds, — loater and 

 lymph; and these, as I also observed, may exist either in 

 combination or separately: most commonly they co-exist. 



The WATER resulting from acute pleurisy is, in most cases, 

 a beautifully clear, limpid, bright-yellow fluid, closely 

 resembling the serum of the blood, though in some cases it
