166 NAVICULARTHRITIS. 



this occasion, the course of a few days' simple treatment restored 

 her to soundness ; so that after a few days of additional repose she 

 returned to her work. On the 27th of April of the following year 

 (1846), however, she returned lame in the same foot ; and this time 

 had a month's treatment, and afterwards a month's rest. For all 

 that, however, in July following she became lame again in the 

 same foot; and now, after treatment, was turned to strawyard, and 

 had a three months' run. Still, under very moderate work she 

 fell lame again in December ensuing ; and though made once 

 more quite sound, on being put to work this summer falls lame 

 in the same foot for the fifth time, in July 1847, never having 

 shewn the slightest symptom of failure in the opposite fore foot. 



1 can, however, relate a case wherein, under very moderate work 

 or rather gentle exercise, for three times the above period, lameness 

 was exclusively confined to the same foot. Eight years ago a 

 general officer became possessed of a remarkably handsome well- 

 shaped hunting mare, who, though never while in his possession was 

 hunted or put to any hard work, fell lame two years afterwards in 

 her near fore foot, for which lameness she became my patient. She 

 got perfectly sound again under treatment, but has never ceased 

 since, at intervals, to go lame ; and at the present time, with the 

 diseased foot much diminished in size, is permanently more or less 

 lame upon it; still, at no time in the course of the six years she 

 has been, off and on, lame in one fore foot, has she evinced any 

 lameness in the fellow foot. 



The action of the groggy horse is directly the contrary 

 of that of the foundered horse : while the latter steps as much as 

 possible upon his heels in order to avoid the pain occasioned by 

 any stretch of the lamincB, the former treads the ground upon his 

 toes, letting his heels down afterwards, in order that the heels may 

 in the least possible degree receive impress from the pressure of 

 weight from above as well as from the ground below. The pit-a-pat 

 pottering gait of the groggy horse is truly characteristic, not to the 

 sight alone, but to the ear even : a "judge" of these matters has 

 but to hear the sound made by the steps of such a horse to at once 

 recognise his ailment. The sensation too, as might be expected, 

 created by the action of the groggy horse upon his rider, is alto-
