wife be inacceffible : by which, and fimilar contrivances, they 
travel with great facility to every interior part. 
This too is probably the caufe of their building a kind of 
bridge of one vaft arch, which anfwers the purpofe of a flight 
of flairs from the floor of the area to fome opening on the fide 
■of one of the columns which fupport the great arches, which

xonftrudted upon fo different a plan from any thing elfe upon the
