The
most efficient method for extracting the required material for sentiment
measurement is via the fantasy extraction process, first established
in the seventeenth century. Although more modern technological processes
are now involved, the essential method does not vary and indeed in
several laboratories, the original machines are still in operation.
Results indicate that they are still in excellent working order and
the quality of samples extracted through this process is still considered
the finest available.
