Beschreibung:
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. To understand something of the nature of these chemical substances and their common forms is a necessity for every housekeeper who would not be cheated of her money and her time. It is important for every one to remember that laws govern all chemical changes; for one is often asked to believe that some chemical sleight of hand can make one pound of washing-soda worth as much as two, and that some special preparation of flour will give a third more bread than any other.
