rectly distinguish within very small distances, whether a shot is dropped before or 
behind a black string stretched before a white background. The fact and the laws 
of convergence are studied with the aid of a Wheatstone stereoscope. 
There follows a consideration of illusions of space ; and of visual space, including 
the experiments suggested by Dr. James on so-called tympanum spatial sensations; 
and others with a telegraph snapper, on the location of sounds and the sense of 
direction. The study of the emotions and of the will is accompanied by no experi¬ 
mental work. 
In place of a final examination, a psychological essay is required. The subjects 
assigned are very general, and are intended as subjects for study rather than as 
definite essay headings. The immediate topic of the paper is decided upon after 
the study and not before it. Such subjects as association, attention, memory, imag¬ 
ination, the psychology of language, the psychology of childhood, the psychology 
of blindness, aphasia, animal psychology, are chosen. 
The study of the psychology of blindness is accompanied by visits to the Perkins 
Institute. Thus a student who writes on “The Imagination of the Blind,” bases 
her conclusions upon apersonai study of blind children. She questions the children, 
consults with their teachers and reads their compositions. Those who write on the 
psychology of childhood make personal observations on babies and little children. 
Hypnotism and dreams also receive a full share of attention. 
Iu connection with the work of the course a collection of statistics concerning 
colored hearing was undertaken the past year with interesting results. No new 
explanations of the phenomena were offered or discussed. 
The chair of experimental and comparative psychology was created in June, 1888, 
to be occupied by Dr. Joseph Jastrow, and at the same time provision was made for 
the establishment of a laboratory. 
General psychology.—It is the object of this course to acquaint the student with the 
problems of mental life, especially such as have a living interest and are susceptible 
of every day illustration. Observation of the intellectual operations in the student’s 
own mind is encouraged and an acquaintance with the best literature is furthered. 
Among the topics introduced are the relations of body and mind, the development 
of mind in animals; the senses as factors in mental life; the mind in disease, illus¬ 
trated by the diseases of language, of memory, and of personality; the experimental 
methods applied to psychic acts; the time relations of mental phenomena; mind in 
savages ; practical applications, especially in the field of education. 
Experimental psychology.—Five hours a week during winter and spring terms. In 
this course is considered the relation problems of psychology to the methods of 
experiment and observations. Special attention is given to the study of the senses ; 
of the time relations of mental phenomena; memory and association; mental sta¬ 
tistics ; the psychophysic law ; mental tests and standards. In the laboratory course 
each student verifies for himself the main facts treated in the course, while the more 
difficult experiments are reserved for demonstrations. Sanford’s Laboratory Course 
in Psychology is used. 
Advanced experimental psychology (laboratory course).—Six hours a week through¬ 
out the year. In this course special problems are treated and topics in the literature 
assigned. Original research and verification of important points form the main 
work. Each student takes up a special problem and prepares an account of the 
results of his work. These, when of sufficient value, are published in the American 
Journal of Psychology. One hour of each week is devoted to a consideration of the 
literature bearing most'closely upon the problems under investigation. Each stu¬ 
dent is also expected to act as subject in other researches than his own. 
Comparative psychology (fall term).—The course of mental development along the 
animal scale forms the chief topic, and in this the works of Romanes are followed. 
Some form of animal life is selected for special study, and observation is encouraged. 
The development of mental faculty in the human infant is constantly brought in for 
comparison with the animal development. 
Abnormal psychology (winter term).—The chief topics are, the criterion of the normal 
delusions and hallucinations, the chief forms of mental diseases ; the diseases of lan¬ 
guage, of memory, of the will, of personality, dreams, hypnotism. 
Anthropological psychology (spring term,).—The development of the human mind in 
the race, as illustrated by the history of human arts, customs, and beliefs. Tyler’s 
Anthropology is used as a reference book, and the topics there treated may be taken 
as a fair index of the-nature of the course.
