ON SOUNDNESS. 
Relations .—On the outer side, with the tendon of the sple- 
nius; on the inner, with the ligamentum colli and complexus 
minor : superiorly, with the complexus major ; inferiorly, with 
the capsular ligament of the articulation formed between the first 
and second vetrebree. 
Structure .—Thick, and almost entirely fleshy. 
Action .—When both muscles act, the atlas (and the head 
along with it) will be elevated. By their alternate action, a sort 
of rotatory motion is given to the head.

ON SOUNDNESS.

To the Editors of “ The Veterinarian.” 
I have read with much interest your account of the three dis¬ 
cussions, or debates, which took place at the Veterinary Medical 
Society, upon Mr. PercivalTs paper relative to the examination 
of horses for soundness:—and although I have ever looked upon 
it as extremely difficult, if not quite impossible, to lay down any 
simple general rule, so perfect as to include every case we may 
have to deal with, yet I must confess I was not prepared to ex¬ 
pect that there would be quite so much discrepancy of opinion 
upon this important subject as seems to have been exhibited on 
these occasions. And I quite agree with you that c it is a subject 
on which, of all others, it seems most desirable for us to come to 
some mutual understanding and unanimous conclusion for how 
can it be expected that lawyers should argue horse causes 
rightly, or, what is of much more importance, that juries should 
be able, at all times, to come to a just decision in matter of this 
kind, when we ourselves cannot agree as to what ought or what 
ou^ht not to be considered soundness?
