those in a transverse direction [sketch] (From When a gland is strongly excited either by the quantity or motion quality of the substance placed on the motor impulse travel further than from one slightly excited; & if several glands are simultaneously excited the motor impulses from all from each all unite & spread still further. As soon as a gland is stim excited receives any excitement it seems to discharge almost suddenly a strong motor impulse, which will may spread to a long distance; but afterwards whilst the gland is secreting & absorbing, the impulse is generally suffices only to keep its own the same tentacle inflected; though thus inflection may last during many days.)

[Insectivorous plants, pp. 275-6: "When a gland is strongly excited by the quantity or quality of the substance placed on it, the motor impulse travels farther than from one slightly excited; and if several glands are simultaneously excited, the impulses from all unite and spread still farther. As soon as a gland is excited, it discharges an impulse which extends to a considerable distance; but afterwards, whilst the gland is secreting and absorbing, the impulse suffices only to keep the same tentacle inflected; though the inflection may last for many days."]
