PROPERTIES OF WOOL. 171 The manner in which the serrations of wool are formed,seems to be, that the wool glands, like other glands,* havea motion ; that is, at the time of the formation of the long-est point of the serration, the wool glands must rise some-what in the centre, and expand, so as to put forth the lar-gest bulk of woolly fibre, and then gradually sink downagain in the centre, so as to form


. The breeds, management. SERRATIONS. No. 1, a fibre of South Down wool as a transparent ob-ject ; No 2, the same, as opaque. No. 3, a fibre of Merinowool, transparent; No. 4, the same, opaque. PROPERTIES OF WOOL. 171 The manner in which the serrations of wool are formed,seems to be, that the wool glands, like other glands,* havea motion ; that is, at the time of the formation of the long-est point of the serration, the wool glands must rise some-what in the centre, and expand, so as to put forth the lar-gest bulk of woolly fibre, and then gradually sink downagain in the centre, so as to form only the smallest diame-ter of the wool. And as hair or wool is formed in glandswhich is formed in the cutis vera, or true skin, this motionwill be necessary, in order to expel the hair or wool throughthe two outer coats of the skin, and also to compress the fila-ments. The serrations are somewhat differently shaped on dif-ferent kinds of wool and hair. Hence, hair being of amore uniform texture, is less pliable than wool
