folid, and forming a Body with it, faving where 
the Beriofiium was flrongly adhering, the Cortex 
of the Bone, after the Exoftofis> or callous Shell 
fpread over it was taken off, being perforated with 
many Blood-veflels, which were larger, and more 
in Number than ufual ; thefe Veflels perforating 
ir, as it was render'd foft and yielding, and the 
indurated callous Matter flicking to it, as well 
within as without, was cover'd with a callous Flefn 
fprouting from it. 
BB, A large Opening made in the external Part of 
the Bone by the Trepan, wherewith the whole 
medullary Cavity of it was laid open 5 this Open- 
ing taking into its Scope 10 or 12 large Holes in 
the Bone, all leading into that Cavity thro' which 
the Matter pent in, and c-aufing the Spina vent ofa, 
at times had worked its Way out by ; which, when 
laid into one by the Operation, favour'd the Ex- 
traction of the tubular Exfoliation, Fig. 2. which, 
tho’ it was intirely loofe in, and detached from 
the Circumference of, the medullary Cavity, yet 
was fo concealed in it, by the Fungus s obturating 
the Foramina in the Bone, as not to have been 
difeover'd before the Opening, it was taken out 
by, was made in the Bone. 
C, A large Hole in the Place where the external 
Procefs of the Humerus formerly flood 5 that hav- 
ing been deftroyed, by the Matter caufing a great 
Cariofity herej which alfo running out of the 
Bone thro' the Foramina made into the Joint, had 
occafioned the Hnchylojis , and the Cariofity of all 
the Bones there.
