strict application of the law of priority. One of the objects of the authors has been to define a method by which the recognition of antecedent work can be consistently secured. They propose that this rule be designated as "Merton rules" for convenience of reference.
Convinced that physical science awaits its next greatest elucidations from the side of biology, Dr. Ernst Mach has made from time to time various researches on sensation, the results of which he states in a volume under the title Contributions to the Analysis of the Sensations (Open Court Publishing Company, $1.25). He here discusses the space sensations of the eye in connection with the innervation of that organ and the physiological aspects of sensations of time and sensations of tone. The conclusions which he has arrived at on these topics show, he affirms, that "there is no rift between the psychical and the physical, no within and without, no sensation to which an outward, different thing corresponds. There is but one kind of elements, out of which this supposititious within and without is formed."
