152 PUEPURA ELEMORRHAGICA. 



mosis of conjunctiva ; painful tumefaction of thighs or fore- 

 arms, occasioned by similar extravasation beneath the fascia, 

 or in the cellular texture of muscles; occasioning limited 

 motion, incapability of flexing the legs sufficiently to rise 

 when down ; sanguineous exudation from skin ; in this state 

 much constitutional disturbance ; accelerated respiration ; 

 partial sweating; frequent, wiry, or full and strong pulse; 

 scanty excretions. As the disease advances the swellings 

 become confluent; greater depositions of lymph, as well as 

 blood, "take place in the thighs and nose, and under the eyes; 

 a sero-sanguineous discharge takes place from nostrils; the 

 Schneiderian becomes nearly black; the membranes not 

 affected, or the buccal, rather paler; the respiration is snuffling, 

 from effusion into the nostrils; the pulse becomes more 

 frequent and feeble; the horse paws, or looks back, or 

 anxiously turns his head from side to side; sometimes small 

 portions of blood are voided from the nostrils, or with the 

 urine, but these are not common in the horse ; great debility 

 quickly supervenes ; the animal totters if made to walk about; 

 his blood becomes thin and pallid ; it separates very rapidly 

 when drawn, and does not, according to Mr Lane, exhibit 

 the normal tendency to assimilate its chylous particles. The 

 urine, in Mr W/s had much albumen in it, was ropy, and 

 coagulated with nitric acid and heat. The skin is often dis- 

 tended, sometimes so much so that, through flexing, very 

 large ulcers are occasioned. 



"Duration. From 3 to 7 days, in fatal cases: if the 

 horse survive that period, though the circumstance is favour- 

 able, it may recur, and prove fatal by deposits in vital organs, 

 or by gradually exhausting the vital powers. 



"Morbid Appearances on Dissection. Dark or black 

 blood effused beneath the skin or fascia, or in the fibres of 

 muscles, giving a dark modena or purple or black colour to
