Excerpt from Harvard Psychological Studies, Vol. 2 The work to be reported in future in the Harvard Psychological Studies will be work done in this new building, and while the re searches reported in the following pages were completed in the smaller quarters of the old laboratory, it seems natural that this volume, which appears at this new epoch Of our work, should give an account both Of our psychological past and Of the development and purpose Of Emerson Hall. The Harvard Psychological Laboratory was founded in 1891 by Professor William James, who had introduced some experimental features into his psychological lecture courses for some time before the formal Opening Of a regular workshop. Professor James started with two large rooms on the second floor Of Dane Hall, and secured an excellent equipment, especially for the study of the psychology Of the senses. He was assisted by Dr. Herbert Nichols, amd'at once gathered a number Of graduate students for research. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The experiments were conducted in the Harvard laborer tory in the spring of 1912 upon five subjects referred to as A, B, C, D, and E. They were all graduate students with a training in experimental methods. The instrument used was a tracing board similar to the one recommended by Whipple. The subject passed the wire attached to the stylus through his coat sleeve, so that it would move freely with his arm and not interfere with its movements. He sat before a table of convenient height with the board directly in front of him. The positive instruction given him was: "Go down the middle of the groove." When the stylus touched the sides a telegraph sounder indicated the contact. The precautions advised by Whipple were observed.
