Of these wonderful creations, I will only bring forward a fewexamples. THE MITE FAMILY. Comparatively few naturalists have studied up the habits andpeculiarities of the mite family. But few of our readers in nat-ural history text-books learn from their pages anything definitein relation to them, either regarding the affinities of these hum-ble creatures, their organization, or frequently singular meta- 67.

This order is dividedinto four families ; viz., the scorpions, spiders, harvestmen, andmites ; the scientific name ofwhich is Acarma. They have arounded oval body, without theusual division between the headand abdomen observable in spi-ders ; the head, thorax, and ab-domen being merged in a singlemass. When mature, there arefour pairs of legs, and the mouthpart consists, as seen in the ad-joining figure of a young tick,of a pair of maxillge ic), which,in the adult, terminate in twoor three jointed feelers; a pair of mandibles (^), often covered with several rows of fine teeth,and ending in three or four larger hooks, and a serrated labium{a).
