readily produce? How could it give each part 
of the leg that figure, proportion, and ftructure, 
which conftitute the member? How could it 
arrange all the parts in that pofition and relation, 
in virtue of which all confpire to the fame end? 
Yo affirm that a certain expanfive force, refid- 
ing in the trunk of the old member, extends the 
veflels, nerves, mufcles, and bones, is faying 
nothing at all: for it is evident, that only a 
fimple ftump or flefhy cone would refult from 
fuch elongation. But could the cone have a 
hand or a foot at the extremity provided with 
fingers and toes ? Could all their articulations be 
prefent; and could the fame order and propor- 
tions prevail? Let imagination extend all the 
fibres of a bony fubftance, nothing will ever en- 
fue but a fimple offeous cone, fo much the larger 
as imagination has rendered the force more 
powerful, and the expanding fibres more dudtile. 
Could the extremity be fafhioned into a certdin 
articulation ? or how could an articulation, which 
infers certain figures, and thefe frequently very 
intricate, arife from the fimple elongation of 
_ftraight or nearly parallel fibres ? How could an 
expanfive power change their direétion, and dif- 
pofe it fo as to produce a joint, and alfo produce 
thofe glands in the joint which are to lubricate 
its parts ?
