Themoulds or loaves are then dried, and if not even or elegantthey are turned in a lathe. Finally they are packed up as loaf sugar. Sugar under-goes no decomposition, and is thecause of non-decomposition inother substances. For this reasonit is employed in preservingfruit, etc. Sugar is obtained frombeet by crushing and rasping theroots, as the cane is Sugar moulds. Spirit of Wine, or Alco-hol, is not a natural is found by the decomposition of grape-sugar by fer-mentation. There is a series of alcohols which exhibit aregular gradation, founded, so to speak, upon one, two, orthree molecules of water. They are called respectivelyalcohols, glycols, and glycerins. Thus we have— „Prophylic „Amylic „ „Butylene „Amylene „ Glycerins. (Ordinary Glycerine is the only one known.) The cetyl and melissylic alcohols are contained in sper-maceti and bee£;-wax respectively. The usual alcohol isthe Vinic, a transparent, colourless liquid which is the
