BM- Within quite recent years, however, a special school q Y P has arisen with the main object of treating the processes of evolution quantitatively.
C, Cellular tissue of the integument; Bm, basement membrane; cire.
Denoting the distance AM by d 1, BM by d2, and AB by 1, we have for the force at M due to the magnetism of the rod H P =d 12 - horizontal component (dla - d 2 3).
Hen d =a the general formula becomes sin' Zm7r Bm: B = (3), showing that, when m is even, B m vanishes, and that, when m is odd, B m: B =1/m272.
The naval architect distinguishes between the stability of form, represented by the righting couple W.BM, and the stability of ballasting, represented by W.BG.
