GASTEITIS. 325 



disease proceeds the congestion within the head increases, 

 either in consequence of the accumulation of food vdthin the 

 stomach, or by a translation of the disease to the brain, and 

 the coma produced causes the horse to press his head against 

 any fixed object, or to rest it in the manger, or hang it between 

 his fore legs; occasionally the head is elevated and placed 

 between the rack staves. If the disease attacks ahorse at grass, 

 he is either found resting his head against a tree, and stupidly 

 fixed to one spot, or moving with feeble steps in one direction, 

 which may be either backward, forward, or round-about. The 

 breathing in. the early stage is not materially disturbed; as, 

 however, the disease advances, it first becomes low and rather 

 protracted ; and when the symptomatic attack on the mem- 

 branes of the braia has produced phrenitic symptoms, it then 

 becomes more hurried. 



The pulse varies in different cases ; sometimes it is oppres- 

 sed, at other times quickened. Spasmodic twitchings of the 

 cutaneous muscles wUl be found not uncommon. When the 

 mucous membranes of the eyes, nose, and mouth present a 

 yellow tinge, biliary suffusion has taken place. Under these 

 symptoms, unless relief is promptly obtauied, either the vital 

 energy becomes so totally suspended that the animal falls to rise 

 no more ; or the distention raptares the stomach ; or it pro- 

 duces such congestion that the patient sinks apoplectic ; or is 

 otherwise worn out by the violence of that phrensy which 

 results from the disease taking on the form of inflammation of 

 the membranes of the brain."* 



Symptoms of the CHEOirro State. — The disease, as I have 

 previously stated, may commence either in an acute or sub-acute 

 form, and pass into the chronic ; and I may also add, that the
