Abstract

1. The average weights of chicken embryos between 5 and 19 days of incubation as found by over 600 weighings may be expressed by a simple exponential equation, W = K t(3.6) where K = 0.668. 2. The velocity of growth (i.e. the percentage increase in mass) is inversely proportional to the incubation age. The product of the two (vt) is a constant (3.6). The negative acceleration of growth likewise decreases with age.
