The deposit or formation of bone corpuscles is not generally from asingle point or centre, as in the ordinary processes of crystallization,or of accretion, forming long spindle-shaped projections; nor is it, inmost cases, derived from a few central points which branch outwardsuntil their opposite extremities meet and become fused. If such werethe fact, motion of the fragments during the process of union, bycausing the fracture of these delicate spindles, would effectually preventunion. That certain motions, and within moderate limits, do not pre-vent union, I shall hereafter illustrate ; and they do not, for the reasonth
