Tertullian says, "If you will not fling away your false hair, as hateful to Heaven, cannot I make it hateful to yourselves, by reminding you that the false hair you wear may have come not only from a criminal, but from a very dirty head; perhaps from the head of one already damned?" This was a very hard hit indeed; but it was not nearly so clever a stroke at wigs as that dealt by Clemens of Alexandria. The latter informed the astounded wig-wearers, when they knelt at church to receive the blessing, that they must be good enough to recollect that the benediction remained on the wig, and did not pass through to the wearer! This was a stumbling-block to the people; many of whom, however, retained the peruke, and took their chance as to the percolating through it of the benediction. FOOD OF ANIMALS. Linnaeus states the cow to eat 276 plants, and to refuse 218; the goat eats 449, and declines 126; the sheep takes 387, and rejects 141; the horse likes 262, and avoids 212; but the hog, more nice in its provision than any of the former, eats but 72 plants, and rejects 171.
