VARIETIES OF DISTORTION OF THE NECK.

Werner saw a horse which after running into and striking a 
carriage with its head lay senseless for three minutes, but on getting up 
was able to resume work. Ten hours later the head was bent towards 
the right; on the left side of the neck over the second cervical vertebra 
was a marked swelling. The gait was unsteady. The neck could not 
be brought into a straight line. Post-mortem examination showed a

transverse fracture of the second cervical vertebra and submemngeal 
haemorrhage. . 
Mongiardino had the opportunity of making autopsies on two horses 
showing torticollis. In one the intervertebral discs between the 3rd 4th, 
and 5th cervical vertebrae were partly torn thiough. The lieac o t e 
fourth vertebra slipped partly out of the cup oi the third w eii le 
neck was bent. In the other case the capsular ligaments and the inter¬ 
vertebral ligaments on the convex side of the neck were strained so that 
the articular surfaces no longer corresponded. The cervical muscles 
on the convex side were paralysed and had undergone degeneiation.
