and cataracts, which serve us for many motions ; and 

 likewise engines for multiplying and enforcing of winds 

 to set also on divers motions. 



We have also a number of artificial wells and foun 

 tains, made in imitation of the natural sources and 

 baths, as tincted upon vitriol, sulphur, steel, brass, 

 lead, nitre, and other minerals ; and again, we have 

 little wells for infusions of many things, where the 

 waters take the virtue quicker and better than in vessels 

 or basins. And amongst them we have a water, which
