In England alone there are about 8000 known,and the number constantly increases. Amongst these then we find inhabitants of the landand of the water, dwellers on the earth and under theearth ; we find scavengers and sextons, fierce huntersand sluggish vegetarians, and, strangest of all, we find aservile race content to live in captivity and minister tothe needs or luxury of another tribe of animals.
