Even in such rarely tamed animals as the common mouse the feeling of jealousy has been known to be so intense as to lead to murder. A young lady, one of Rev. J. G. Wood’s correspondents, had succeeded in taming a common brown mouse so completely that it would eat out of her hand and suffer itself to be taken off the floor. She had also a tame white mouse in a cage. One morning when she went to feed the white mouse, as was her usual custom, she found it lying dead on the bottom of the cage, and beside it was its murderer, the brown mouse. The cage being opened, the latter made its escape, as though fearful of the consequences that might ensue, but how it had managed to gain admission was always a mystery. Instances are on record where the jealousy of a rival has been restrained for long years through fear, and has ultimately broken out when the cause of the fear has been removed. A case of the kind came under our notice some few years ago. There were two cocks, belonging to different breeds, whom fate had placed as denizens of the same family. One was a magnificent dunghill cock, and the other a Malay, a cowardly caitiff, that was kept in fear and subjection by the former. In the course of events the dunghill cock suddenly died. His rival, coming by chance on his dead body, and perceiving that the time had come to wreak out the mixture of hatred and revenge that had lain smouldering in his bosom for years, instantly sprang upon it, kicked, spurred and trampled upon the lifeless bird, and, standing upon the corpse, flapped his wings in triumph, as it were, and crowed himself hoarse with the most disgusting energy. He immediately took possession of the harem, but he was far from being the noble, generous and unselfish creature that his predecessor had been. Again, comparing man with beast, it is at once apparent that the bird in this instance acted exactly as a savage does when his enemy has fallen, for the savage not only exults over the dead body of an enemy, especially if the latter has been very formidable in life, but also mutilates in futile and silly revenge the form which he feared when alive.
