74 DADD'S VETERINARY MEDICINE AND SURGERY. 



The abdomen appeared " tucked up," as the saying is. This arose 

 from the rigid state of muscles of the abdomen. The hind limbs 

 presented a straddling appearance, and the fore ones were unnat- 

 urally advanced far beyond the axis of the shoulder-blade ; the 

 bowels were constipated ; the pulse was wiry, and the respirations 

 were accelerated and laborious. The case was diagnosed as tetanus 

 from puncture of the off hind-foot. It appeared that the animal 

 had picked up a nail, five days previous, which was withdrawn by 

 a blacksmith, and the foot was dressed in the usual way. The 

 treatment was as follows : 



The rigid muscles were rubbed, twice daily, with a portion of 

 the following antispasmodic liniment: 



No. 8. Cod-liver oil 12 oz. 



Oil of cedar 4 oz. 



Sulphuric ether 3 oz. 



The application of the liniment was continued during a period of 

 ten days, in which time four drachms of Indian hemp were daily 

 placed on the tongue. The jaws now relaxed, so that the patient 

 could eat bran mashes. At the expiration of two weeks all signs 

 of tetanus had disappeared. 



Vertigo (Dizziness or Giddiness). 



The term vertigo signifies giddiness or dizziness. It is usually 

 the result of some latent disease within the brain ; and when that 

 is present, any exciting cause, which we shall presently refer to, 

 may bring on a fit of vertigo. The following article, by surgeon 

 Haycock, will, perhaps, prove interesting to the reader : 



" By vertigo is meant a chronic disease of the horse, chiefly in 

 dicated by a disturbance of the sensitive faculties, occasioning 

 derangement in the ordinary functions of life. Much that is incor- 

 rect has been written regarding the seat, properly so-called, of the 

 evil. At present, most veterinary surgeons are agreed in seeking 

 the proximate cause, not as formerly, on the brain, but in the ab- 

 dominal organs, and on considering the cerebral affection as purely 

 secondary." 



Vertigo often succeeds acute disease of the brain. 



Causes. — Its chief exciting causes are confinement in hot and 

 badly-aired stables, cold, extreme fatigue, blows and injuries on 

 the head, indigestion, unwholesome or too much food in proportion
