The section of the phalanx (Fig. A) exhibited a quite compact osseous 
structure—the Haversian canals being for the most part round, and 
rather small, though in some places they were irregularly shaped or oval, 
and larger. The intervening bone lamelle were of unusual thickness,

and presented in the majority of cases, bone corpuscles with canaliculi. 
In some cases, however, no bone corpuscles were present, and the lamellze 
appeared to be merely calcified by saturation with bone salts. : 
The bone corpuscles were small and often indistinct ; in some places they 
were unusually round, but in others they presented the normal elongated 
shape; their canaliculi were invariably very poorly developed, and often 
could not be discovered. 
With regard to the mode of arrangement of the bone lamellw, they 
were always developed concentrically with (parallel to the walls of) the 
Haversian canals, and in no instance were any lamelle found whose di- 
rection was parallel to the external surface of the shaft.
