lows : la the dog and the cat there is a 

 period extending from birth to about the 

 time of the opening of the eyes character- 

 ized by reflex movements, the sway of in- 

 stincts and the absence of intelligence. 

 The advance in movement, first of the limbs 

 and later of the head and face parts, together 

 ■with the psychic progress associated with 

 this, is correlated with rapid development 

 of the cortical centers for the limbs in the 

 first instance, and later for the head and 

 face in the period immediately following 

 the blind stage. This is more rapid and 

 more pronounced in the cat than in the 

 dog, and is correlated with greater control 

 in the cat over the forelimbs and with cer- 

 tain physiological and psychic developments 

 characteristic of the cat; similar observa- 

 tions were made upon rabbits and cavies. 

 The psychic manifestations of the pigeon 

 and fowl have not the same sort of cere- 

 bral cortical correlates as the animals re- 

 ferred to above. 



7. The Organization of Practical Worlc in 

 Psychology. By Lightner Witmer, of the 

 University of Pennsylvania. 

 Under the designation of practical work 

 in psychology was included: (1) The direct 

 application, whether by professional psy- 

 chologists, practicing physicians or teachers, 

 of psychological principles to therapeutics 

 and to education. (2) Such psycho-physi- 

 cal investigation of mental conditions and 

 processes as may serve to throw light upon 

 the problems that confront humanity in the 

 practice of medicine or teaching. (3) The 

 offering of instruction in psychology to the 

 students of medicine or to teachers that 

 contains a promise of future usefulness to 

 them in their respective professions. Thus 

 the plan has a view to the professional prac- 

 tice of psychology, to research and to in- 

 struction as these stand related to the two 

 professions of medicine and teaching. In 

 order that psychology may become a useful 



possession of the medical man, details of 

 organization must be perfected that wUl 

 bring about a union of the department of 

 psychology with the professional depart- 

 ments of the medical school. Professor 

 Witmer then went on to suggest details of 

 organization as part of a plan for the de- 

 velopment of research work and instruction 

 useful to the community and to the teacher. 



8. Psycho-physical Tests on Normal School and 

 Kindergarten Pupils. By Miss Mary P. 

 Harmon. 



These tests form part of a general scheme 

 which proposes the development of a series 

 of tests which shall be applicable alike to 

 the oldest and youngest pupils in all grades- 

 from the kindergarten to the normal school. 

 The intention is to repeat, from year to year, 

 a series of experiments of which a few are 

 included in this preliminary report, as the 

 children now in the kindergarten pass 

 through the various grades. The tests re- 

 ported upon included family statistics, age, 

 height, weight, lung capacity, simple reac- 

 tion time to sound and rate of free-arm 

 movement. 



9. Personal Experiences under Ether. By 

 Wesley Mills, of McGill University, 

 Montreal. 



This paper related the experiences of the 

 writer during and immediately subsequent 

 to the adminstration of ether, together with 

 a later experience that seemed to produce a 

 profound impression. 



Brother Chrysostom, of the Manhattan 

 College, presented an informal paper, en- 

 titled A Prelindnary Study of Memory; and 

 Professor E. C. Sanford, of Clark Univer- 

 sity, gave a Demonstration of an Eye Plethys- 

 mograph. 



A paper by Mrs. C. Ladd Franklin, on 

 Color Blindness and Willem Pole : A Study in 

 Logic, was read by title.
