Ex-tracts of nux vomica, belladoima, henbane, andgentian are also prepared here, and the first twoare standardized. Scammony resin is here ex-tracted from the root, and the preparation is asfar as possible rendered soluble in ether withoutresidue, great care being taken to free it fromglucose or any matter soluble in water. The resinwhen dried presents a close resemblance in ap-pearance to virgin scammony, but has a sweet,not a cheesy odor. Considerable experience is nc-. .iCONnUM grinders in I/Ondon, but for many jears—indeed,until about ten vears ago—were almost the onlymanufacturers of essential oils in this countrywho, besides supi)lving their usual manufactures,distilled or pressed for the wholesale trade suchoils as sandal wood, croton, and others that arenot made from plants cultivated in this oils chiefly made at I<ong Melford at presentare those of sandal wood, caraway, dill, cloves,lavender, jiejipermint, and orris root.
