                <lb/>
              things use strange names, which do not properly belong to the metals, and
                <lb/>
              because some of them employ now one name and now another, invented by
                <lb/>
              themselves, though the thing itself changes not. </s>
              <s>These masters teach their

              disciples that the base metals, when smelted, are broken up; also they teach
                <lb/>
              the methods by which they reduce them to the primary parts and
                <lb/>
              remove whatever is superfluous in them, and by supplying what is

              all of which they carry out in a crucible. </s>
              <s>Whether they can do these things
                <lb/>
              or not I cannot decide; but, seeing that so many writers assure us with all

              earnestness that they have reached that goal for which they aimed, it would

              seem that faith might be placed in them; yet also seeing that we do not

              read of any of them ever having become rich by this art, nor do we now see
