TUESDAY, NOVEMBER 9, 1948 State, Penn Research Staffs Discover Gall Stone Detector Surgeons demonstrating the new electro acoustWc gall stone detector. which "broadcasts" location signals from the loudspeaker at the left. Penn State squelched the Uni versity of Pennsylvania on the grid battlefield Saturday to an swer a six-year latent question of football superiority. But last month the two universities, in the rare role of allies, fought and triumphed on another battlefield. —The field of medical darkness. The winning play was the de velopment of a sound detector for gall stones. At Penn State, the play was called by 24-year-old Edward G. Thurston, research engineer at the Naval Ordnance Labora tory. Ed, a native Pittsburgher from Avalon, did the work under the direction of Dr. Eric A. Walker at the request of Dr. Charles K. Kirby, an instructor in surgery on the staff of the University of Pennsylvania Hos pital. In a spectacular three-month run, the Penn-Penn State combi nation solved the medical puzzle of gall stone location. Previously, because of the lack of suitable equipment, some gall stones were missed and recovery from the operation retarded or a second operation found neces sary. The detector when probed inside the bile duct, carries sound waves to an amplifier and "broad casts" the signal of undiscovered stones. A distinct "ping," distin guishable from healthy tissue, is produced when the probe con tacts a stone. Surgeons get their signal with earphones or over a loudspeaker. The "broadcasts" were recently demonstrated publicly for the first time at the Hospital of the University of Pennsylvania dur ing the course of a series of sur gical operations and televised to 4,000 physicians and surgeons at- PRINTING Multilithing Addressograph Service COMMERCIAL PRINTING Glennland Bldg.

The new instrument will be placed upon the open mafket without patent claims so that the detector will be available to the greatest number of people need ing this type of medical aid. Ed Thurston, who ran this medical touchdown play, was graduated from the Carnegie In stitute of Technology in electri cal engineering in 1945. He re ceived his master's degree the following year and came to Penn State July 1, 1948. ,NOW AT YOUR WARNER THEATER IT Pr— tot.ooll.:Nisliop • - . 1 040V 1 00 111G 11111 Is OUT THE DAILY COLLEGIAN, STATE COLLEGE, PENNSYLVANIA Jim Crow count of his purchases at the commissary. He has never known what his cotton or , corn or pea nuts sold for. Technically, half the crop he raises is his. But he never has sold an ounce of cot ton or a single peanut. Here is the pattern throughout the South. • Every Negro knows it and ac cepts it. It's a custom, a tradi tion, just as basic as Jim Crow. No Negro dares buck the system. Everywhere I went, and I talked with at least a score of share croppers, I heard the same ex pression: "If you go to figure behind The Man you're gonna git trou ble." For that' matter every Negro share-cropper I talked to admitted that he couldn't "fig ure." "The Man jes' calls it off," they told me, each with a wry smile.

Last year he raised two tons of peanuts and 11 bales of cotton. At $2OO a bale and ton that would have been s2,6oo—Henry's share $1,300 less, of course, his "furnish" and other expenses. He got $242 cash. Shamefacedly he admits he can't "figure." He wouldn't "figures behind `the Man'" any way. Year before, he says, he made seven bales and a ton and a half of neanuts. He had a hospi tal bill to come out of his share and wound up with $3O cash for his year's work. But Henry has a garden of his own and raises a few hogs each year. Apparently he's convinced he is doing all right for himself. On many plantations "The Man" won't waste good cotton land in gardens for his croppers, (Continued on page eight) Student Union Concert Band Begins Tryouts Concert Band tryouts for stu dents who are not members of the orch-.-stra or marching band will begin tomorrow, announced J.
