“By the following experiments Luchsinger believes himself to have found the most irrefutable proof of the existence of a really antagonistic action of atropin and pilocarpin on the excretory glands, and to have finally disposed of my thesis on physiological antagonism. When he had fully convinced himself of the functions performed by the sweat glands on the hind feet of chloroformed cats, by cutting both hip nerves, and stimulating their peripheral ends, and also by injecting 0·01 grs. of pilocarpin under the skin of the back; when he had succeeded in completely arresting all secretion of sweat by the injection of 0·001-0·003 grs. of atropin under the skin of the back, so that the very strongest stimulation of the hip nerves remained entirely without effect, he always succeeded in causing a spontaneous secretion of sweat in the balls of the toes by the injection of 0·301 grs. of pilocarpin either into the feet or under the skin of the back. If he injected less than 0·001 grains of pilocarpin, the natural secretion of sweat might not result, but could be excited by stimulation of the nerves which had been without effect before. The feet into which no pilocarpin had been injected remained dry and could not be brought to perspire by electrical stimulation of the nerves. Luchsinger considers these experiments to be practically the most simple and theoretically the most explicit, and hence he believes that I shall also allow myself to be convinced by them of the fallacy of my third thesis. Our experiments on the same subject have shown us however on the contrary that Luchsinger’s theories are only partially founded on correct observation, also that the conclusiveness of his experiments only appears to him so simple and clear because he has not thoroughly worked out the whole question, and has allowed himself to be duped too rapidly by the surprising results which happened at first.”--Rossbach, “_Neue studien ueber den Physiologischen Antagonismus der Gifte_,” Pflüger’s _Archiv._, Vol. XXI., pp. 2-3.
