Abstract
One consequence of the rise in population and in the standard of living during the nineteenth century was that the demand for solid fats for soap and food tended to outrun the supply. Adequate supplies of liquid fats, such as whale-oil and seed- oils, were available; the invention of a process for hardening them in the first decade of this century has ensured plentiful and cheap supplies of solid fats to meet the ever-increasing demand.
