iV. An ExtraB of a Letter from Bernard Con- 
nor, M. D. to Sir Charles Walgrave, Fuh» 
lijhed in French at Paris : Gimng an Account 
of an Extraordinary Humane Sceleton, rphofe 
Vertebrae of the Bac\^ the Kibs^ and few- 
ral Bones' down to the Os Sacrum ^ were aU 
firmly united into one folid Bone ^without Joynt- 
tng or Cartilage. 
SIR, 
Aving iately feen part of an Human Scekton, all 
the Bones whereof were fo united as to make but 
one continued Bone without Articulationj I thought it • 
might be acceptable to the Curious to be prefented with 
fame Account thereof. 
This was not an eaiire Scekton, confiding only- of 
the Os Iliumy the Os Sacrum^ the five Fertebne oi the 
Loyns, ten of the Back, five entire P^ibs on the right 
fide, and three on the left ; the bottcms or ends of the 
orher were clofely united to the tjm{vtt& Apophyfes q{ 
their Vertelrce. The Fertehre of the Neck, ih.z CU" 
vicuU Sternum were U'antiog, All thefe Banes ^ 
which Naturally are 3 8, each feparateaod diftind from 
another, were here fb ftraightly and intimately joyned, 
their Ligaments perfediy Bony, and their Articulations 
fo effaced, that they really made but one uniform con- 
tinuous Bone ; fo that it was as eafie to break one of the 
Vertehrte into ty'vOy as to disjoynt or fcparate it from 
the other Vertebra, or the Ribs, or ^^ 0% Sacrum fronl 
thofe of the Ilia, Nor could I obferve any greater di« 
ftindion between all theft Bones than is ufually feen in 
Adult Perfons between the Os Fuhis ^ the Ifchion, and 
E JliMm^
