DISEASES OF THE HORSE'S FOOT 



Lungwitz's article on the subject, Colonel F. Smith, A.V.D., 

 had arrived at similar conclusions by working on the same 

 methods. 



It is unnecessary for our purpose here to minutely 

 describe the exact modus operandi of these two experi-

I. Left Fore-foot Shod and Mounted to recognize the Sinking 



of the Sole. 



a, Iron plate covering the inner half of the horny sole; b, openings in 

 the same, with screw-holes for the reception of the contact-screw 

 c (the part of the sole under the plate is covered with tinfoil, 

 which at d passes out under the outer branch of the shoe, and 

 becomes connected with the tinfoil of the wall ; in order to give 

 the freshly applied tinfoil a better hold, copying-tacks are at e 

 passed through it into the horn, and one is similarly used to 

 protect the tinfoil at the place where the contact-screw touches 

 the latter) ■ /, holes with screw thread for the fastening of the 

 angle required to measure the movement of the wall, and also 

 for the fastening of the conducting-wire, g ; //, conducting-wire 

 passing from the tinfoil; i, isolated nails. 



II. Bar-shoe with Openings. 



a, Near the inner margin and in the longitudinal bar ; b, for the recep- 

 tion of the contact-screw c; d, openings for fastening the angle 

 and the conducting-wires. 



menters. Briefly, the method of inquiry adopted in each 

 case was the ' push and contact principle ' of the ordinary 

 electric bell, and the close attention which was paid to 

 detail will be sufficiently gathered from Figs. 35 and 36. 

 After numerous experiments with the depicted contact-
