ReadNov.27, jrjsj the year 1751, I communicated to the 
A academy at Rouen the cafe of Charles 
Tehee, a child of three years old, of the village of 
Pitre, &c. from whom I had extracted an entire tibia, 
exoftofed and carious in its whole extent, between 
the two articulations, which had remained found: 
this great deficiency of bony fubftunce was entirely 
fupplied again by nature, and the patient acquired a 
new tibia, much firmer than that which he had loft. 
The advantages which muft neceftarily accrue to man- 
kind, and the credit which forgery muft acquire 
from observations of tins fort, would induce us to 
hope that inftances of them might become more fre- 
quent ;
