Fourth Experiment .—A colt, two and a half years old, was 
neurotomised on the 1st September, 1852, in the right fore leg. 
Sensibility was extinguished for two months, then it returned 
at some points. This animal was sacrificed eight months 
after the operation. At the autopsy the microscope demon¬ 
strated the regeneration of some of the nerve fibres. The 
measurements of the hoof were made regularly during three 
months, and yielded the following results :
