TETANUS — MEGRIMS. 55 



up if touched ; eyes watchful, brilliant, the haws, their 

 natural shield, shooting across the eyeballs ; pulse little 

 increased, but rather hard and incomjjressible. 



Second stage : Muscles cramped generally ; head drawn 

 upward and backward, presenting deer-like aspect ; hence 

 the name "stag-evil;" tail elevated and tremulous ; limbs 

 stretched ; countenance haggard, ghastly ; eyes wild, star- 

 ing, protruded, haws shooting over balls, if excited ; other- 

 wise dull and sunken ; ears erect, rigid ; nose protruded ; 

 nostrils dilated; gait hobbling; jaws more firmly locked, 

 &c, &c. 



Third stage : Symptoms much the same, but intensified, 

 and distress more general. Sometimes the windpipe is 

 opened to prevent suffocation. Fatal. 



Remedy. — Put in dark box; perfect quiet; loosely in 

 slings. Aloes, aided by nutritive mashes, gruel, molasses. 

 Salines in drinking water, kept within reach. Will suck 

 up sloppy food even when the jaws are closed. Foment 

 or poultice wound ; remove any cause of irritation and 

 apply anodynes. Powdered opium and cannabis indica 

 extract, 30 grains each, softened by admixture of ammo- 

 nium acetate solution, 3 times daily among molar teeth. 

 Bromides and chloral hydrate give temporary, sometimes 

 permanent relief. (For doses, see pages 13 to 29.) 



MEGRIMS (VERTIGO, DIZZINESS, STAGGERS), 



Is brain disturbance (cerebral congestion). Its usual 

 cause is tight or badly fitting collars. This seems to be 

 proved by the fact that horses subject to it are free of it 

 if worked with a band across their breast ; further, by 

 the fact that loosening the collar soon stops a fit. If the 

 collar is not loosened manually, the horse will plunge 

 about till it falls, and thus loosen it itself. The disease 

 lias other causes, such as general plethora (too much blood) 

 increased action of the heart, disturbed vaso-motor (vessel 

 movement) activity, &c.
