nally, whatever may be the fimplicity of it's ufe, 

 this is remarkable, it is formed of two fimilar

There are other interior confonances, which

 they will ever be able to trace the windings of this 

 labyrinth. Why, for inftance, (hould the pain 

 which attacks a foot, make itfelf felt, fometimes,

 having a fencing bout one day with a comrade, 

 who, as well as himfelf, made ufe of his undrawn

 right arm, and no medical affiftance has ever been 

 able to reflore the ufe of them *.
