ard to the first I took note,
among other facts, of the following:

_17th week._--In the seizing movements, as yet imperfect, the gaze is
fixed partly on the object, partly on _his own hand_, especially if the
hand has once seized successfully.

_18th week._--The very attentive regarding of the fingers in seizing is
surprising, and is to be observed daily.

_23d week._--When the infant, who often throws his hands about at random
in the air, accidentally gets hold of one hand with the other, he
regards attentively both his hands, which are often by chance folded.

_24th week._--In the same way the child fixes his gaze for several
minutes alternately upon a glove held by himself in his hands and upon
his own fingers that hold it.

_32d week._--The child, lying on his back, _looks_ very frequently _at_
his _legs_ stretched up vertically, especially at his _feet_, as if they
were something foreign to him.

_35th week._--In every situation in which he can do so, the child tries
to grasp a foot with both hands and carry it to his mouth, often with
success. This monkey-like movement seems to afford him special pleasure.

_36th week._--His own hands and feet are no more so frequently observed
by him without special occasion. Other new objects attract his gaze and
are seized.

_39th week._--The same as before. In the bath, however, the child
sometimes looks at and feels of _his own skin_ in various places,
evidently taking pleasure in doing so. Sometimes he directs his gaze
to his legs, which are bent and extended in a very lively manner in the
most manifold variety of positions.

_55th week._--The child looks for a long time attentively at a person
eating, and follows with his gaze every movement; grasps at the
person's face, and then, after _striking himself on the head_, fixes his
gaze on his own hands. He is fond of playing with the fingers of the
persons in the family, and delights in the bendings and extensions,
evidently comparing them with those of his own fingers.

_62d week._--Playing with his own fingers (at which he looks with a
protracted gaze) as if he would pull them off. Again, one hand is
pressed down by the other flat upon the table until it hurts, as if
the hand were a wholly foreign plaything, and it is still looked at
wonderingly sometimes.

From this time forth the gazing at the parts of his own body was
perceptibly lessened. The child _knew_ them as to their form, and
gradually learned to dis
