In three out of five trials involving transplanted apple and sycamores (Acer platanoides) significant differences emerged between trees treated with potentiated gold and those treated otherwise. Although the scope of two other trials was too limited, these trials nonetheless tended to corroborate the suggestions of the other trials: that the enhanced vitality resulting from treatment with potentiated gold leads to greater growth, greater leaf cover, lower aphid infestation and a lower incidence of wilt disease. The plane trees showed better leafing in the crown; this might support the hypothesis that gold links cosmic and terrestrial action. (1710)
