BI-QUAD'RATE, n. [L. bis, twice, and quadratus, squared.]

In mathematics, the fourth power, arising from the multiplication of a square number or quantity by itself. Thus 4 x 4 = 16, which is the square of 4, and 16 x 16 = 256, the biquadrate of that number.


Pertaining to the biquadratic or fourth power. Biquadratic equation, in algebra, is an equation raised to the fourth power, or where the unknown quantity of one of the terms has four dimensions. Biquadratic parabola, in geometry, is a curve line of the third order, having two infinite legs tending the same way. Biquadratic root of a number, is the square root of the square root of that number. Thus the square root of 81 is 9, and the square root of 9 is 3, which is the biquadratic root of 81. – Encyc.

BIRD, n. [burd; Sax. bird, or bridd, a chicken; from the root of bear, or W. bridaw, to break forth.]

  1. Properly, a chicken, the young of fowls, and hence a small fowl.
  2. In modern use, any fowl or flying animal. It is remarkable that a nation should lay aside the use of the proper generic name of flying animals, fowl, Sax. fugel, D. vogel, the flyer, and substitute the name of the young of those animals, as the generic term. The fact is precisely what it would be to make lamb, the generic name of sheep or colt, that of the equine genus.
