CLASS MAMMALIA. 47 Mammals, which might otherwise become too numerous. Its food is not confined to these, for I have found Beetles, Lizards, Slow-worms, and other small fry in the stomachs of those examined. It is rare for the Weasel to interfere much with game. In some parts of England, the Weasel, when small, is called a " mouse-hunter," and right well it deserves this name. When chasing a mouse, it keeps to the scent as well as the best foxhound, and seems regardless of onlookers. I have said " keeps to the scent " ; but it would be more accurate to say that it never passes over the scent, even when in full gallop. Its method appears from observation to be that of making casts diagonally across the track of its prey. This plan of hunting, I have an idea, is not confined to the Weasel. Although albino specimens of this species are rare, Mr. Miller Christy has, on the authority of Mr. J. Pettitt, taxidermist, of Colchester, recorded (Zool., 1895, p. 19), one killed near that place about December 20th, 1892. It was pure white, had pink eyes, and its flesh was of an unusually pale colour. Mustela erminea, Linn. Stoat. This rapacious, active, and destructive member of a specially blood-thirsty family, is very common throughout Essex. Persecution, from every quarter, seems to have little influence in diminishing its numbers.

Although mice and small creatures contribute to its sustenance, its favourite prey consists of the larger mammals. Hares, Rabbits, and Rats are chased by it from scent, as most persons who live in the country can testify from observation. The two former, after being pursued for some distance, > appear to resign themselves to their fate,
