cold produces what 

 is termed lamina- 

 tion, causing the iron 

 to separate in layers as shown in Fig. 6 a. But as the compression of

shearmg holds the edges together, it 



,^ does not show itself until driven into 



the hoof, when the 

 horny fibres cause them 

 to separate while being 



driven, and one portion i s 

 forced into the foot and the oth- 

 er out through the wall of the 

 hoof, thus causing lameness, 

 lockjaw and death as has 

 been frequently the case 



since the introduction of cold rolled nails, which the records of state 



courts, as well as the testimony of celebrated horse owners, abundantly 



show. 



This drawing was taken from 



a hoof to show the result of a 



cold rolled and sheared pointed 



nail which produced the death 



of a valuable animal and for 



which carelessness the owner 



received no remuneration.
