LAMENESS IN HORSES. 
By William Percivall, M.R.C.S. and V.S. 
[Continued from p. 127.] 
NAVICULARTHRITIS. 
TWELVE years after having communicated to Messrs. Coleman 
and Sewell the results of his researches into the morbid causes of 
“ groggy lameness,” i. e. in 1828, Mr. Turner read a paper on 
the subject before the Veterinary Medical Society*: prefacing it 
by stating that it was a “ copy of the above-mentioned com- 
munication, with this reservation — that although twelve years’ 
experience in active practice since that period had induced him to 
draw some other inferences which may not exactly accord with 
the first impressions, yet they will seem to harmonize in the aggre- 
gate adding, “ I believe I am correct in stating, that before 
the year 1816, the (St. Pancras) College Museum, splendid as it 
then was, contained but a solitary specimen of the navicular dis- 
ease, and which was simply a diseased navicular bone, divested 
of its ligaments and tendon ; but Mr. Coleman has on several 
occasions since candidly acknowledged in his lectures, that he 
had looked upon it previously to that time as a specimen of dis- 
ease of very rare occurrence.” 
* This paper was published in The Veterinarian for February 1829, 
and was followed by a second paper “ On the Symptoms and Cure of the 
Navicular Disease,” read December 4th, of the same year, and published in 
The Veterinarian for January 1830. Both these papers, together with 
some observations on shoeing — also published in The Veterinarian, with 
additional remarks, were collected into a work, published in 1832, well 
known to the profession, under the title of “ A Treatise on the Foot of the 
Horse,” &c. &c. By J. Turner, M.R.C.V.S., London, 1832.
