=Changes in Plant Characters.=--From experiments upon the cultural evolution of _Cyclamen latifolium_, W. T. Thiselton Dyer finds that, when once specific stability has been broken down in a plant, morphological changes of great variety and magnitude can be brought about in a comparatively short space of time. It appears that though sudden variations do occur, they are, as far as we know, slight as long as self-fertilization is adhered to. The striking results obtained by cultivators have been due to the patient accumulation by selection of gradual but continuous variation in any desired direction. The size which any variable organ can reach does not appear to be governed by any principle of correlation. Large flowers are not necessarily accompanied by large leaves. The general tendency of a plant varying freely under artificial conditions seems to be atavistic--or to shed adaptive modifications which have ceased to be useful, and to revert to a more generalized type, or to reproduce characters which are already present in other members of the same group. But this statement must be accepted with caution. The most remarkable phenomenon in the cultivation of the _Cyclamen_ is the development of a plume or crest on the inner surface of each corolla segment. This shows that the plant still possesses the power to strike out a new line and to develop characters which would even be regarded as having specific value. =Hanging an Elephant.=--One of the elephants in Barnum and Bailey's show, having repeatedly shown signs of insubordination and bad temper, it was finally decided to kill him. From a note in Nature we get the following account of his execution: After considerable discussion it was decided to strangle him. A new Manila rope was loosely wound three times around his neck, and his legs, fully stridden, were securely chained each to a post firmly driven into the ground alongside each limb. The animal was intentionally not isolated from his fellows, as it was feared that if placed by itself it would become restive and ill-tempered. The rope surrounding the beast's neck had one end secured to three strong pillars in the ground, some distance away and slightly in advance of the fore feet; and the other, which terminated in a loop, was hooked to a double series of pulleys, to the tackle of which ninety men were attached. When all was ready, the slack was gently, quietly, and without any apparent annoyance to the elephant--which kept on eating hay--taken in till the coils round its neck were just taut. The word was then given, "Walk away with the rope." Amid perfect silence the ninety men walked away, without apparently any effort. So noiselessly and easily did everything work that, unless with foreknowledge of what was going to take place, one might have been present without realizing what the march of these men meant. The elephant gave no sign of discomfort either by trunk or tail. Its fellows standing close by looked on in
