lively, and irritably attentive to surrounding objects. 

 It was necessary to give her one drop of tincture of opium, 

 which restored the usual state and disposition for repose. 

 Voluntary vi- Fourth day. She can follow an object with theTeyes, 

 **°" when her attention is excited, and now and then unequi- 



vocally smiles during her observations on surrounding 

 objects. 

 Expression of Fifth day. Her pleasure at viewing luminous and other 

 artfc^uiation. objects is expressed, not only by the general features, 

 but by efforts of the mouth, protruding the lips, advanc- 

 ing and withdrawing the tongue. She has once or twice 

 pronounced the usual first voluntary articulation of in- 

 fants, kit and ac-ku. She is very attentive to language, 

 and answers with smiles, terminating in the word ac-ku^ 

 and a lively exertion of the legs. She has, apparently 

 Optic axes ad- for the first time, began to attend to the adjustment of 

 ^""^^ the optic axes, and probably the concomitant focal ad- 



justment of the eye. She is delighted to lie and contem- 

 plate the breast at a little distance, after having satisfied 

 her appetite. In this position, as well as when attentive 

 to the kind countenance of the parent who speaks to her, 

 the mouth is protruded and occasionally modified to the 

 indication of pleasure resembling the action of sucking, 

 and all adjustments of the optical axes are tried, from 

 squinting, to the usual very regular position of the eye*. 

 Notion of fall- Sixth day. The habits of attention, and answering 

 •"S- \^Y smiles, by attempts at articulation, and by muscular 



exertions, are so much strengthened to-day, that the re- 

 currence of those effects is now very frequent. This day 

 she has first betrayed an apprehension of want of support, 

 or, as it is commonly called, fear of falling. Whether this 

 be an acquisition from improved powers of observation, 

 or the consequence of some accidental shock, I am at «i 

 loss to conjecture, 



• Since the time above referred to, I have witnessed a much 

 earlier voluntary use of the eyes, in another infant. Before the 

 end of the first hour after birth, her attention bting directed to a 

 window, she cried from displeasure at its being shut, and ceased 

 upon its being again opened; and she not only followed my hand 

 with her eyes, when moved before them, but altered the positions 

 of their axes accordingly as the distance of the hand was varied.
