94 ABSCESS IN THE SUBLUMBAll REGION IN A MARE, &C. 
laid her down on plenty of good litter. Her efforts, with her 
fore legs, to raise herself were incessant, but her hind ones re¬ 
mained in any posture in which we chose to place them. She 
was covered wdth perspiration, particularly about the base of the 
ears, the shoulders and the flanks; the respiration accelerated; 
the nostrils dilated, and the membrane of the nose of an intense 
red ; the pulse full and hard ; the temperature of the hind limbs 
cold, compared wdth that of the fore ones. The tumour of yes¬ 
terday now presented nothing but a little opening without en¬ 
largement. 
Twosetons, dipped in a stimulating fluid, were introduced into 
the thighs : the animal expressed a great deal of pain during the 
operation. This sensibility appeared to me extraordinary. I 
pricked the paralyzed limbs in various places, and as low as the 
coronet, and everywhere the sensibility was excessive. Ten 
pounds of blood were taken from the jugular; stimulating fric¬ 
tions were applied over the loins, and anodyne drinks and muci¬ 
laginous injections were resorted to. 
6^/«.—-In the same state. The sensibility as great as on the 
former evening. The appetite good; frequent meanings ; con¬ 
tinual agitation of the fore limbs ; the heat of the w'hole of the 
body diminished ; general perspiration, and also general debility. 
Six drachms of nux vomica were administered. 
Hth. —The pulse very feeble; cold sweats ; the paralyzed limbs 
as acutely sensible as before. Eight drachms of the nux vomica, 
after which there was slight agitation of the limbs ; the pulse was 
more developed, and there appeared to be intense inflammation 
of the conjunctival membranes. 
Qth, A.M.— The body covered with cold sweat ; respiration dif¬ 
ficult ; pulse not to be felt; the sensibility of the hind limbs still 
retained. She died at five o’clock in the afternoon. 
Post-mortem Examination. —The floating portion of the colon 
and some portions of the small intestines were slightly inflamed. 
, The right pleural membrane was injected—black. The lung on 
the same side was black and gorged with blood ; the animal had 
lain on that side during the w^hole of her illness. The tissue of 
the lungs was easily torn. The right cavities of the heart were 
red ; the tissue of that organ was pale and flaccid. 
The lesions in the neighbourhood of the tumour that has been 
spoken of, were confined to the sub-cutaneous tissue : but in 
raising the left clio-spinal muscle (the longissimus dorsi) towards 
the last dorsal vertebra and the first lumbar, we found under it a 
collection of purulent matter, which penetrated into the spinal 
cavity by means of the canals for the passage of the nerves. The 
pus which it contained was generally black, with green points or 
specks, and had a carious smell. Many of the vertebrae had
