pletely offify’d : In tlie Centre 6f this bony Sub- 
ftance we found about a Quart of mucilaginous 
Liquor, no ways fetid, (though it was then ten Days 
from the Operation) whofe Colour and Confiftence 
nearly refembled that of Linfeed Oil in which we 
obferv’d many little bony Subftances loofe and float- 
ing, limilar to many others adhering to the internal 
Surface of the Cavity, all which had nearly the Ap- 
pearance of thofe irregular Incruftations, which in 
hollow Rocks are fometimes made by the dropping of 
petrifying Waters. After the Operation, every Cir- 
cumftance of the Cure proceeded as 1 could wiih, and 
the Stump is now healed. 
It feems well worth obferving, that the Parts 
above the Tumour were very little alter’d from their 
natural State. The Cartilaginous Extremity of the 
Femur was perfedly fmooth; nor had the Rotula 
fuffer’d any other Injury except the Offification of 
the Ligament by which it is fixed to the Tibia j but 
the fuperior Extremity of the Fibula was wholly loft 
in the Tumour. 
May we not juftly admire the Goodnefs of a Con- 
ftitution, which could bear fuch enormous Exten- 
fions in the Integuments, the Tendinous Fafcia, and 
even the Bone itfelf, without Pain and Inflamma- 
tion ? Or can we fufficiently wonder, that the Fluids 
fhoLild be fo little difpofed to putrify, as to bear fo 
great a Diminution in their Motion, and for fo long 
Time, without vitiating the Conftitution, or tainting 
even the Parts affeded ? Herewith (Sir) I beg your 
Acceptance of two Portraits of this furprifing Cafe 
(See T,a b. II.) : The firft Figure rcprefents the Limb
