14 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 anima] 
had picked up a nail, five days previous, which was withdrawn by 
4 blacksrnith, 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........ccecceee taveseae 12 02 
Oilof cedars wes cw siels oad wea enecaw ate 4 oz 
Sulphuric ether...........c0ceee sence 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. 
Vertico (D1zzINE8S 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 
Haycocx, 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 heen written regarding the seat, properly so-called, of the 
evil. At present, most veterinary surgeons are agreed in seeking 
the proximate cause, nct as formerly, on the brain, but in the ab- 
dom‘nal 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 
tadly-aired stables, cold, extreme fatigue, blows and injuries on 
V4e head, indigestion, unwholesome or too much food in proportion
