This descent usuallyoccupies in the common fowlfrom 16 to 2-1 hours or not muchlonger period, and the processof seg^mentation is therefore acomparatively rapid more obvious phenomena attending this process, as observed by Coste(No. 22, iii.) and Kolliker (Xo. 28 i. p. 70), consist in the occurrence, first of a gTOOveor cleft across the cicatricida in a determinate direction, which appears to be atright angles to the long axis of the whole egg. This is soon followed by anothergroove, which crosses the first nearly at right angles or intersects it at oppositesides in two separate places. In a third stage the four segments of the germinal.
