Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. When Mary Elizabeth Hall first brought her discovery to my attention, I thought that it was indeed one that would revolu tionize candy-making, both that of the amateur at home and of the manufacturer.
