Much of this will illustrate more or less voluntary movements by child

On my theory of Expression of fear & anger ─ it cannot be said that in struggling, the movement of the muscles, actually cause the accelerated force of heart, red surface, & rigid muscles but both are increased together by the whole living frame ─ so if struggle prolonged, that the sweat, hard breathing, & throbbing heart, & bloodless surface cannot be said to be due to the tired muscle, but to the whole exhausted nervous system. ─ Hence when emotion occur, which lead to their actions, they the muscular are not put in action, the others are.—

saliva flows properly from

imitation of salivary glands & jaws move ─ but not being voluntary, the idea of food excites them

children will suck anything: little birds open beak

─ also in vomiting. ─ yet in sneezing if one expects or trys it ─ will not ─

(sneezing & coughing established habits) & therefore out of will, like moving voluntary muscle in uneven order) is very difficult, & when muscle not quite under will, as respiratory muscles come into play, they act connectively ─ // p. 50 ─ muscles of abdomen brought into violent action is [stranging], when there is nothing to propel out ─
