HEPATITIS. 435 



suffering some inward pain ; but it is manifestly not of an 

 acute kind. He has not lain down during the past night ; 

 his dung-balls are small and unusually dark-coloured ; his 

 bowels constipated ; his urinary discharges scanty ; and there 

 exists a great deal of fever in the system. The fever runs 

 on, and commonly, on the second or third day after its onset, 

 turns out to be what farriers call '' the yellows ;" recognised 

 by them as such from the remarkable circumstance of the 

 mouth and eyes having assumed that colour. The inner 

 surfaces of the lips and cheeks, the tongue, the conjunctive 

 membrane, and, in some cases, the transparent cornea and 

 iris as well, turn yellow, indicating the diffusion of bile over 

 system ; and the same is further demonstrated by the deep 

 golden dye of the serum of the blood. I have likewise 

 observed yellow matters floating about in the aqueous 

 humour. The dung-balls are deeply imbued with bile; and 

 in some cases enveloped in a viscid, bilious mucous matter as 

 well : their colour is that of a reddish-brown, leaving, when 

 rubbed upon white paper, much the same stain as solid 

 opium would. If any urine be caught, it will be found to 

 be thick, to exhibit the same bilious tinge, and to deposit, 

 on standing, a copious lateritious sediment. The horse will 

 probably be found lying down quietly, and not appear easy ; 

 though from time to time turns a dolorous look at his 

 side, and soon after rises up again : he will probably be dis- 

 covered lying upon his left side, and should the right be 

 pressed against, he will flinch or bite, or otherwise express 

 tenderness there. Hurtrel d^Arboval, indeed, speaks of heat 

 and tumefaction of this side. When standing, now and 

 then he is found pointing or favoring one (the off) fore 

 limb. The pulse becomes quick, strong, and bounding. 

 The breathing is disturbed in some cases; in others tran- 

 quil. From being simply dull and heavy, the animal turns 

 sometimes quite stupid ; at times indeed vertiginous, so tliat 

 he staggers in his walk, and is unsteady even in his stall. 

 In this state, should no relief be afforded him, the patient is 

 in danger of apoplexy on the one hand, and, on the other, 

 of bursting his liver.
