the nut-bone, and this with that of the foot, 

 fo as that thefe three parts were united, and the 

 coronary-bone had preferved the freedom of its 

 motion in the joint. The horfe was no longer 

 lame, but in walking inclined a little upon the 

 heel. 



Observation XIX. 



A horfe, upon whom the extirpation of the 

 frog by the thread was performed, had the 

 Tendo Achillis much injured; I could not well 

 tell whether it happened from cutting out the 

 thread, or from the acrimony of the topical ap- 

 plications; the tendon however was deftroyed 

 as that mentioned above, the nut-bone was laid 

 bare, and the tendon putrefied at its infertion. 

 After his cure was compleated, he died in five 

 or fix months. And I found the nut-bone co- 

 vered, by a kind of ligament, all over that 

 part which was connected with the upper part 

 of the tendon : this new tendon was as a liga- 

 ment, and adhered to the nut-bone, which was 

 ofllfled to it ; but it was more than twice as thick 

 as in its natural ftate. It remains to know 

 whether this excrefcence proceeds from the ten- 

 don, or from the covering of the cellular mem- 

 brane or from other membranes ; but it is time 

 andobfervations which mud lead us to the know- 

 ledge of this.
