GROGGY LAMENESS. 167 



gether peculiar : thus, a man both blind and deaf, mounted upon 

 such a horse, would be able to tell, the moment the horse came to 

 trot, Avhether or not he was groggy. 



Grogginess must be regarded as a state of incurable 

 LAMENESS. And yet, when such a state is not confirmed, i. e. 

 has not from the length of time it has existed, and the alterations of 

 structure in the feet which have consequently taken place, become 

 established, grogginess frequently admits of alleviation, though 

 cure may be hopeless. Even in such a case, however, it rarely 

 happens that any permanent relief is conferred ; seldom, indeed, 

 any beyond what disappears as soon as the horse comes to return 

 to any hard or severe work. Conscious of these facts, people 

 seldom bring us groggy horses for treatment, while we, for our 

 part, are equally shy in having any thing to do with such forlorn 

 cases ; and therefore it is that groggy horses are kept at work ; 

 and in certain situations, such as four-wheeled drausfht and agricul- 

 tural employ, a great deal of useful work they will perform. The 

 remark of old coachmen on the road used to be — ''They didn't 

 care how lame ahorse was a/bre, so that he retained the sound use 

 of his hind limbs;" and for draught this is the really practical and 

 proper view of the matter, the tug of draught depending principally 

 on the hind quarters. 



Pathology of Navicular thritis. 



While other lamenesses of the foot were plainly traced to their 

 seat, and had their nature satisfactorily developed, there remained 

 one, of which, from its seat lying out of the way of ordinary or 

 superficial observation, the pathology continued wrapped in ob- 

 scurity, or rather enshrouded in error, the supposition and gene- 

 rally received opinion being that it lay in a part with which, as 

 has since been demonstrably proved, it had never any connexion. 

 What we now recognise as navicularthritis was acknowledged to 

 be a foot lameness, and was imagined to be located in the coffin 

 joint. Nor was this groundless supposition effaced from the minds 

 of veterinarians until Mr. Turner produced irrefragable evidence,
