The question would naturally arise whether there may not be a limit reached where electricity would completely overcome the attack of mildew and stimulate the plant to a healthy and vigorous condition throughout its entire growth.  From the fact that the hardiest, healthiest, and largest heads of lettuce grew over the greatest number of currents and nearest the electrodes, it would seem that electricity is one of the agents employed by nature to aid in supplying the plant with nourishment and to stimulate its growth.  To what extent plants may be submitted to electrical influence, or what strength of current is best suited to them and what currents prove detrimental to their development, have not been determined as yet, but it is desirable to continue this research until some definite information shall be gained on these points.  Probably different varieties of plants differ greatly in their capacity for enduring the action of electric currents without injury—­experiment alone must determine this.

It has been proved that the slow discharge of static electricity facilitates the assimilation of nitrogen by plants.  Faraday showed that plants grown in metallic cages, around which circulated electric currents, contained 50 per cent. less organic matter than plants grown in the open air.  It would seem from the researches of the latter physicist that those plants requiring a large percentage of nitrogen for their development would be remarkably benefited if grown under electric influence.—­Massachusetts Agricultural College, Bulletin No 16.

[A very interesting article on the Influence of Electricity upon Plants, illustrated, is given in SUPPLEMENT 806.  It presents the results of the studies of Prof.  Lemstrom, of Helsingfors.]

THE TREATMENT OF RATTLESNAKE BITE BY PERMANGANATE OF POTASSIUM, BASED ON NINE SUCCESSFUL CASES.

By AMOS W. BARBER, M.D.,[1] Cheyenne.

[Footnote 1:  Governor of Wyoming.]

Poisoned wounds, inflicted by the fangs of the rattlesnake, are happily more rare each year, since, as the country is becoming more populated, the crotalus is rapidly being exterminated.  Yet, considering the recklessness which characterizes the cow boy in his treatment of this reptile, it is astonishing that this class of injury is not more common.  Thus it is the invariable custom among the cattlemen to dismount and destroy these snakes whenever they are seen.  This is readily accomplished, since a slight blow will break the back.  This blow is, however, generally delivered by means of the quirt, a whip not over two and a half feet long, and hence a weapon which brings the one who wields it in unpleasant proximity to the fangs of the reptile.  A still more dangerous practice, and one which I have frequently seen, is a method of playing with the rattlesnake for the delectation of the cow boy at the expense of a “tenderfoot.”
