 the matter up by consulting his veterinary surgeon. 

 A distinction must be made between what would

 full development of the latter. In the former, the 

 cartilage either at the inner or the outer side feels 

 indurated, and has only lost part of its elasticity. 

 It is more prominent than normally, but even in 

 this stage, the writer believes that it is not un-

 Does an indurated lateral cartilage constitute un-
