. A practical treatise on fractures and dislocations . f that under certainfavorable circumstances bony union mayoccur, but not enough to establish it be-yond all doubt.

We have never yet seen a specimen which,upon a careful examination, proved satisfactory; but unless our wantof conviction can be shown to be the result of a wilful blindness, weshall demand protection against the assaults and insinuations whichhave so frequently fallen upon those who ventured to doubt theauthenticity of every specimen which was laid before I repeat, that it seems to me probable, that under certain favorablecircumstances this union will occur; these favorable circumstanceshave relation to several conditions, such as age, health, decree ofseparation of the fragments, laceration of the periosteum and capsule,. Vertical section of Mrs. Wakeleesfemur, acetabulum and capsule. NECK, WITHIN THE CAPSULE. 373 treatment, &c. Eobert Smith thinks it is not likely to occur unlessthe fragments are impacted, but Sir Astley Cooper, as we have alreadyseen, admitted its possibility whenever the reflected capsule and theperiosteum were not torn, and at the same time the fragments werenot displaced. If to these conditions we were to add moderate butnot extreme age, with good health, we can see no sufficient reasonwhy, under judicious treatment, bony union might not occasionallybe expected. But such a combination of circumstances is probablyexceedingly rare; and, what is more unfortunate, if they exist, thefracture is not likely to be recognized, and the surgeon will fail toavail himself of those advantageous coincidences which might, ifunderstood and properly treated, secure a bony union.
