In a note on the fruiting of Wistaria sinensis in Europe communicated to the Linnaean Society, by Mr. W. T. Thiselton Dyer, the author avers, from his own and others' observations, that plants trained on a garden wall at Glyon, east end of the Lake of Geneva, yield abundance of brown tomentose pods annually. Near the town of Geneva, however, fruiting is of rare occurence, but again more frequently at Lyons and the Rhone valley. Fruiting, he suggests, may be a question of temperature, and not of nutrition dependent on presence or absence of support to the stem and branches. From the above and other data Mr. Dyer fails to see the evidence of the antagonism of the vegetative and reproductive forces as asserted to be the governing law according to Mr. T. Meehan's experiments, and lately quoted by the Rev. G. Henslow. If such barrenness were the case with its scandent habit, then W. sinensis would probably already be extinct. - London Gardener"s Magazine.

[We have always to allow much for brief condensations of authors' papers; for if a short paragraph could perfectly convey an author's meaning, there would be no use in a long chapter. In the above instance Mr. Dyer's meaning has probably not been correctly rendered, for if one observer show that the manner of growth affects nutrition, and that when nutrition is affected fertility varies,it would be very absurd to infer that he believes nothing but systems of training would affect nutrition. In our climate we find " questions of temperature " affect nutrition just as much as "questions of training," so that granting the correctness of Mr. Dyer's observation, it is not easy to see what bearing it has on the other "evidence" which Mr. Dyer "fails to see." The logic is so weak that we prefer to believe that Mr. Dyer's points have not been clearly put in the above paragraph. A leading point in Mr. Meehan's communication to the Linnsean Society was to show that insects and cross-fertilization had nothing to do with the seeding of the Wistaria; and it seems to us that this note of Prof. Dyer's rather confirms than antagonizes this view.

If the fruiting "may be a question of temperature," of course insects are "out in the cold" in the experiment. - Ed. G. M].
