  The process described in the following pages has now been in use for twelve months, and I have much satisfaction in stating that it has, in almost every instance where it has been adopted and carried out with care and attention, yielded results which leave scarcely anything to be desired. The present Edition might more properly be termed a reprint, as the alterations in the text do not extend to more than a few matters of detail, which experience has shewn to be desirable, the principles of the process remaining undisturbed.
