Both the sensitive and horny laminae are bent backwards, and 

 haemorrhages have taken place at the base of the sensitive 

 laminae. 



m the horny sole we are able to deduce evidence relative to 

 the duration and nature of the injury. 



When, for instance, the stain is not to be found in the 

 superficial layers of the sole, but is only discoverable by

Where the stain is met with in the superficial layers, of 

 horn, and is quickly pared out, then the injury has been 

 inflicted Some time before, and has not been repeated.
