    CCXLV.—Narcissine: an Alkaloid from the Bulb of the Common Daffodil (Narcissus pseudonarcissus). By Arthur James Ewins. In 1878 a paper was published by Ringer and Morshead (.7. Physiol. ? 1, 437), entitled “On the physiological action of narcissia, an alkaloid obtained from the bulb of the common daffodil (Narcissus 'pseudonarcissus)'’ This work contained a detailed account of experiments carried out on men and frogs with an alkaloid or with extracts containing the alkaloid, which had been obtained by Gerrard from the bulb of the common daffodil. From experiments carried out with extracts obtained from bulbs in the resting stage and from bulbs of the flowering plants, the authors concluded that the action of the alkaloid present in the extracts from the resting bulbs was similar to that of pilocarpine, whereas that present in the extracts from the bulbs of the flowering plants closely resembled atropine in action. The alkaloid obtained by Gerrard from both extracts nevertheless appeared to be the same in general chemical properties.
