446 SUMMARY OF PROGRESS IN ANTHROPOLOGY IN 1891. 
discussed in Europe. The measurements were taken in Bengal, the 
Northwestern Provinces, and the Panjab, in 1886-1888. Topinard’s 
measures and instruments were employed, with the exception of the 
naso-malar index of Oldfield Thomas. (J. Anthrop. Inst. May, 1885), 
(2) Continuation upon the architecture of the nervous system. 
(3) The motor regions of the brain. The middle portions of both 
hemispheres contain motor centers. 
(4) The sensory centers. The motor centers form a dividing line in 
the cortex, behind which lie the sensory centers, and in front is an un- 
occupied area which is left out of the discussion. 
(5) Cerebral localization in the vertebrate series becoming less per- 
fect as we pass downward. 
(6) The principal explanations which have been offered for the phe- 
nomena of cerebral localization and some of the points of contact be- 
tween these phenomena and psychology. 
Dr. Donaldson’s observations on the brain and several sense-organs 
of the blind deaf-mute, Laura Dewey Bridgman, in the American Jour- 
nal of Psychology (iv, 248-249) is accompanied with a bibliography of 
ninety-two titles, bearing upon the study of the brain and sense organs 
in nealth and disease. These titles are numbered and references to 
them in the text are made by the numbers and not by foot notes. 
Dr. Edmund C. Sanford presents in the American Journal of Psy- 
chology (Iv, 141-155) the outlines of a course of study of lectures in 
physiological psychology. This is done not only to encourage the estab- 
lishment of laboratories, but to assist college men and others, who are 
not prepared to make original investigations, in repeating the experi- 
ments of the best establishments. In each case the apparatus and the 
method of applying it are minutely described. The following program 
is followed: 
I. The dermal senses.— (1) Sensations of contact. (2) Sensations of 
temperature. (3) Sensations of pressure. 
Ii. Static and kinesthetic senses—(1) Recognition of the posture of 
the body as a whole. (2) Sensations of rotation. (3) Sensation of 
progressive motion. (4) Musclesense. (5) Innervation sense. (6) Sen- 
sations of motion. (7.) Sensation of resistance. (8) Bilateral assym- 
metries of position and motion. 
In an elaborate paper on the psychology of time, Mr. Hebert Nichols 
reviews the terms and expressions for time in the classic authors, fol- 
lows the conception of a psychological recognition of time historically, 
and completes his essay with a review of modern psycho-physical experi- 
ments in this direction. As a summary of the experiments of Horing, 
Mach, Vierordt, Koliert, Estel, Mehner, Giass, Stevens, Hjner, and 
Miinsterberg the most conclusive resuit may thus be summed up. 
Nearly all persons, under nearly all conditions, find a particular length 
of interval more easily and accurately to be judged than any other. 
This “indifference point,” or interval of best judgment, is very vari- 
able for different individuals and for different times and conditions.
