WSEASE8 ANJJ TIIEIE TEEATMENT. 



All tlic subjects Avhieli supplied the specimens illustrated were 

 selected on account ot'indifutions whicli led me to investigate Ihcm. 



When I first saw this animal after death, ni}' whole mind was 

 absorbed in the case, and it would have been of no use if I had only 

 detached the foot, strictly so called, for examination. When trying 

 to make out anything natural or unnatural about the foot, 1 always 

 take a great part of the Vunh, so as to include the whole carpal 

 region; and if a hind limb, then of the tarsal region. In this in- 

 stance I divided the radius a little above the knee. I had per-

 as the fore-arm of a man, and to the touch felt hard like a cable. 1 

 shall refrain from entering into a detailed descri])tion of the condi- 

 tion of these })arts, ni}-- olijcct being now to show plainly hoAV one

 the original state of the case — an effect for a cause. I knew Ihat 

 the massive, hard bunds were but syni]itoms of serious conditions 

 below; that it was a coiling of these bands, with the design of 

 shortening their track, 1)}^ which the range of bones could be held 

 firm, and in a vertical line. AVith such notion;'. I proceeded to dis- 

 sect the iimb, first by disarticulation at the j)astern-joint, and 

 placing the foot in the macerati<Mi-tub for six weeks; meanwhile I 

 dissected the ])arts above, confirming my views of the conditions, 

 and greatly extending my knowledge. Tn due time, the hoof be- 

 coming detached, I dissected the foot, with the result shoAvn in Fig.
