HOG, n. A bird remarkable for the catholicity of its appetite and serving to illustrate that of ours. Among the Mahometans and Jews, the hog is not in favor as an article of diet, but is respected for the delicacy and the melody of its voice. It is chiefly as a songster that the fowl is esteemed; the cage of him in full chorus has been known to draw tears from two persons at once. The scientific name of this dicky-bird is _Porcus Rockefelleri_. Mr. Rockefeller did not discover the hog, but it is considered his by right of resemblance.

UBIQUITY, n. The gift or power of being in all places at one time, but not in all places at all times, which is omnipresence, an attribute of God and the luminiferous ether only.
