330 Mr. White on the Regeneration 
membrane, when it is partially deftroyed, is re¬ 
produced in membrane.” All furgeons muft have 
cbferved this, that in old diflocations which have 
not been reduced, there is always fome degree 
of motion more or lefs in the diflocated joint, 
except it has been complicated with a fra&ure. 
In a converfation I lately had with Dr. Monro, 
he confirmed Dr. Hunter’s opinion, with the 
relation of the two following difle&ions. He 
immerfea a dead child in warm water, till it was 
perfectly foft and flexible; he then diflocated 
the ftioulder. Upon difledling the parts, he 
found the capfular ligament lacerated. 
A man in Edinburgh was killed by a fall from 
a horfe, and his fhoulder was at the fame time 
diflocated Upon difieftion in this cafe allb, he 
found the capfuiar ligament lacerated. 
Dr. Monro told me, he did not in the leaf!;, 
doubt what Mr. John Hunter had advanced on 
this fubjedt; and informed me, that he had a 
cafe, laft winter, of a patient who had an exfolia¬ 
tion of half the lower jaw, particularly of the 
whole condyle on the left fide ; the loft part was 
regenerated, he had the entire ufe of the jaw, 
and the joint was as perfect as on the other fide, 
except being a little fuller, and attended with 
a trifling degree of hardnefs. I had the fatisfac- 
tion of feeing the exfoliated bone amongft his 
valuable collection, and found the head of the 
bone perfect, except a little carious on one fide.
