Photometer, in the Illumination Laboratory, measuring light output of electric lights. STANFORD STUDENTS who plan to become electrical engineers enjoy the privilege of working in well-equipped laboratories under instructors who have a national reputation. For those interested in the field of elec- tric power, Stanford offers, in addition to the usual training in fundamental principles, an opportunity to work in the famous Ryan High-Voltage Labo- ratory. This is provided with transformers capable of developing a peak potential of 3,000,000 volts and is duplicated by no other university in the world. During the last few decades the field of communication has become one of the major divisions of the electrical industry. Again in this field, Stanford students work in a laboratory that attracts graduates from universities all over the country. For those inter- ested in the growing field of illumination, the Electrical Engineering Department offers a thorough training in the fundamental principles of the subject, supplemented by an oppor- tunity to make practical measurements of light sources and their effectiveness in the illum- ination Laboratory. To meet the growing need for business as well as technical training, a course is now offered graduate students in cooperation with the Graduate School of Business, which combines business with engineering. 16 A Cathode Ray Oscillograph in the Ryan Laboratory.

The Psychical Research Laboratory was established in 1912 through the generosity of Thomas Welton Stanford. Professor John Edgar Coover, who died last February, held the Fellowship in Psychical Research from 1912 continuously until his retirement in 1937. During this 25-year period of public service, Professor Coover conducted experiments on the nature of clairvoyance and telepathy, se- ance, phenomena, and sublimal cues for perception. The new Psychical Research Fellow is Dr. John L. Kennedy, who this year has been studying the claims for extra-sensory perception, based on card-guessing. He is also investigating electrical brain-waves by means of an elec- troencephalograph. 15

This man is working on an advanced subject in the field of illumination, that of a really high pressure mercury vapor lamp. By first discovering the method of sealing a tungsten wire in quartz, and by working with quartz capillary lamps, a water-cooled one was developed which is operated with pressures running up from 100 to 300 and higher atmospheres. With the increasing pressure, the light approaches that of sunlight, the temperature of the lamp being about 8000 C. and the sun is measured as 6000 C. at its surface. In the operating room the lamp can be used for interior lighting. In movie projectors, a lamp of ' g in outside diam- eter for each inch length of capillary pro- duces over 10,000 candle power, but only the heat of a common incandescent lamp. A lamp of one foot in length will light up an airport as if it were day. These lamps are now being studied for market consumption. 17
