What weight thefe Reafbns may have with an Intelli- 
gent Reader, I (hall not pretend to decide. 
Excrefcences not unlike this of the Skuil,have been ob- 
served in moft other Bones of the Body(theOf Fe^rofim^ 
Jncm^MalleusJStapes,&LC, not excepted) and the Difeafe is 
commonly QzWtd SpinaFefitofa. It is remarkable,that the 
Bones of Children and young Bodies (efpecially their 
Appendages) are more fubjed to the like Accidents, than 
tho& in Years; by reafon their FihrilU are much fofter 
and apt to extend, whereby that part of the Bone it 
felf grows Tumid, and frequently becomesCarious • and 
this probably might give occafion for Impofing the 
Nam.e of P^darthrocace on that Difeafe, which is vul- 
garly calfd. The Joint'Evil: When the Cartilages on 
the extremities of Bones in their Articulations are ero- 
ded Cand their^ Appendages thus Difeas'd) the Bony 
Fibres fometimes Germinate and Unite both Bones, in 
fuch a manner, that they afterwards appear to be one 
continued one, as I have feen in the Hip and 
Thigh-bone, and again in the Thigh bone the 27- 
lia and Patella^ and frequently in the OJfa Tarfi^Meta- 
tarfi^ and Bones of the Toes ; many Inff ances of which 
are mentioned by Writers, m \k\tVertelr£ and other 
Bones. This Unitiorj of Bones at their Articulations, 
may alfo happen through a defed of the Mucilage.
