In Dr. Barton's ingenious paper, to which I have already referred in the chapter on Pasturage, the plants enumerated as yielding poisonous honey are _Kalmia angustifolia, latifolia_, and _hirsuta_; _Rhododendron maximum_, _Azalea nudiflora_, and _Andromeda mariana_. The honey of these is stated to have proved injurious both to dogs and the human species. _The symptoms_ it usually produces _are dimness of sight or vertigo, delirium, ebriety, pain in the stomach and bowels, convulsions, profuse perspiration, foaming at the mouth, vomiting and purging_; in some instances, _temporary palsy of the limbs_, but very _seldom death_. The best mode of treatment is not yet ascertained; though the similarity of the symptoms, the Doctor says, would induce us to pursue the same plan as in counteracting other narcotic poisons. In those cases, _early vomiting_, whether spontaneous or induced by art, removes the disease at once; and _cold bathing_, so useful in other spasmodic or convulsive affections, is employed with considerable advantage by both Natives and Europeans. This should seem to be one of those cases in which the _stomach-pump_ would be peculiarly beneficial, from the promptness and certainty of its action. To the credit of the genus of plants last named, it should be mentioned that one species (_Andromeda nitida_ or _lucida_ of +Bartram+) affords abundance of excellent honey; hence the name of _honey-flower_ is given to it, by the country people in _Georgia_ and _Carolina_, not however merely from the circumstance just mentioned, but from the regular position of the flowers on the peduncle, which open like the cells of a honey-comb, and from the odour of these flowers, which greatly resembles that of honey."--_Barton_. "As most of the plants enumerated in the above list are now introduced into our gardens, and the _Datura_ (_common Thorn Apple_) has long become perfectly naturalized, they might be supposed to injure the British honey. Most probably, however, their proportion to the whole of the flowers in bloom, is too small to produce any such inconvenience; whereas on their native continent they exclusively cover whole tracts of country, as instanced above in the Jerseys." _Evans_, B. ii. p. 95. +Tumefaction of the Antennæ.+ The antennæ, in this disorder, become swelled at their extremities, which resemble the bud of a flower ready to open, and they assume a yellow colour, of which the forepart of the head shortly partakes; the bees becoming gradually languid and dying, if they have not timely assistance.--This malady occurs about the month of May. +Pestilence+, or +Faux Couvain+ (_as Schirach calls it_).
