Mr. Keeler is of the state criminology depart- ment. “In"c order to have a Wdemonstration, President Raymond asked the as— sembly to choose a member of the faculty and a member 01 the stu- dent body. Professor Schommer and George Moore were selected with loud acclamation. 'Mr. Keeler started his demonstra- tion by first telling’how the ma~ chine came to be invented. Fifty years ago, he said, the association method was used to try to detect the guilt of a man. This method consisted in naming a word and (having the subject respond by say— ing the first thing the leading word made him think of. Irrelevant words were mixed up with the words with real meaning, and by timing responses, a good measure of whether the suspect was trying to hide his guilt was obtained. This method started a search to see if some machine could be made to register pulse action and respira- tory action to accomplish the same purpose. Several men succeeded in making machines to register either one, but Mr. Keeler’s is the first one to co—ordinate both. Suspects are brought in for the machine test after other methods of cross—examination have failed, explained Mr. Keeler. They are re- assured and put at ease and there are hooked up to the detector by means of a blood pressure attach- ment, which goes around the arm, and a tube, which goes around the chest to measure breathing action. Their pulse actions and breathing actions are recorded on a graph by means of which it can be told whether the suspect is telling the truth or not. An innocent man may have a jumpy chart at first, but it calms down at the end. The chart of a guilty man starts out at a low level and climbs steadily. Professor Schommer was hooked up to the machine and shown one card out of a stack of ten. The card was then mixed in with the rest of them. Mr. Keeler asked Professor Schommer to answer, “No," when asked, “Is this the card,” no matter which card he was shown. By reading the chart at the end of the test, Mr. Keeler determined the correct card. Pro— fessor Schommer’s graph rose steadily until the correct card was shown, and then it fell. George Moore was a. more difficult case, as he did his best to beat the machine. He took deep breaths, and short breaths, and held his breath, but he could not control his pulse. Mr. Keeler was able to determine the card. Armour Institute of Technology, Chicago, Illinois Cycle Receives Honorary Rating The certificate of award won at the Ninth National Yearbook Con~‘ test of the National Scholastic Press held at the University of Minnesota by the Cycle Yearbook of Armour Institute has been Announcemenm oA Graduation Ready The Senior announcement com- ,mittee, headed by John W.

McLaughlin talncd, the dance must be run at a charge of $7. 50 per couple, which would mean that the aflalr would necessarily be less elaborate than the formals given in former years.

Braun were presented the Scarab medals won by them on their de- signs for the problem, “A Com- memorative Hall," at the last meet- ing 01' the fraternity on Thursday, March 20, 1930. The members of the Scarabs meet twice monthly to have lunch at the Men’s Grill in the Marshall Field Building. These meetings are strictly informal and there are generally many of the alumni present. The problem was to design a hall, dedicated to those who fell in the World War. The competition in- cluded the entire Sophomore class and the two best of all the designs submitted were chosen for the med-- als. The first prize was a silver medal and the second prize a bronze. Insurance Manager Outlines Office Work Mr. Harry G. Casper was the speaker at the lei—weekly meeting of the Fire Protection Engineering Society, Wednesday, March 19, in Science Hall. Mr. Casper explained the position and duties of the man» ager of an insurance company. He is well qualified to speak on this topic as he is manager of three companies Their system of receiv: is the low state of the finances of the junior class. There is no money "left in the class treasury to make up for the loss which the formal usually incurs. The affair must be absolutely self-supporting. Mem- bers of all classes can sign the peti~ tion.

Prerssor Huntley Seeks Village @ifice Professor Huntley of the Mechan- ical Engineering Dept. is not only a scholar but a politician as well. He is running for Trustee of the Village of Riverside. There are three to be elected and as yet only three have been nominated. The election is to take place on April 8, 1930. The Trustees are analogous to the Councilmen in the city government. That is, they have charge of the government, and direct the policy of the village, its expenditures and taxes. SENIOR POSITIONS Mr. W. S.

The various types of poli~ cies are all numbered and to file a record of the policy, these numbers are punched on small cards. These cards are automatically separated by a most intricate machine, which has long fingers. The Fire Protects were invited to see the machine at any time. 15. J.

E. department made an inspection trip last Tuesday to the Civic Opera House. The day was switched from Friday to Tuesday for the convenience of the Opera House staff. Professor Holmes said that the trip was made to demonstrate the last word in building construction, especially from a fireproof stand— point. Other features noted were the excellent lighting system, the enormous height of the stage to prevent shadows, and the unusual mechanical devices such as the hy- draulic pumps to raise the stave.

After a few numbers by the or— chestra, Dr. Raymond presented the speaker of the morning with a few reminiscent words of introduc— tion. Dr. De Forest told of his coming to Chicago in the fall of 1399 to take a ' position with the Western Elec- tric Company, after having been graduated from Yale University the preceding June. no related his first connections with the institute as an assistant instructor in the Electrical Department and how he was given a free rein in the labor- atories in return for his services in teaching classes. It was very interesting to hear Dr. De Forest’s version of the first trials of his wireless telegraphy, from the Institute to the Auditori— um and the Lakota Hotel and from a yacht on the lake to a receiver on the four-mile crib. Aided by Professor Dr. De Forest realized that, the need in wireless was avdetector so signals could be heard in phones. So with the aid of Professor Glar— ence Freeman and knowledge Library he perfected an electrolytic detector which supplanted the troublesome coherer. In New York, Dr. De Forest ex- perimented with hot gases and their conductivity of electric im- pulses. Using first the Bunsen flame and then an electric arc, he finally developed the three elec- trode type of tube in 1906, employ- ing platinum wires and a perforat— ed sheet of metal at first and then ‘ the developed grid type with woven wires for the third electrode.
