"physiological significance." A letter from Dr. Parmele to Mr. Ganger dated July 19, 1950 mentions some testing to be done by Dr. Killian. Testing was to involve the determination of carbon monoxide in the blood of humans before and after smoking Embassy cigarettes and before and after smoking regular-size cigarettes. In addition, the measurement of finger-tip skin temperature and blood flow, under the same conditions had apparently already begun. It was presumed that these tests were a measurement of nicotine and its removal by the passage of smoke through long and short butt lengths. It was also mentioned in this same letter that Dr. Killian would "attempt to develop ways and means of proving the physiological significance of acidd tars, animals or humans." (04362087/2088) Around this same time, Dr. Killian began using rabbit eye tests for comparing the irritant actions of Embassy, Old Gold and various regular-size cigarettes. Dr. Killian set up physiological studies by "outside" corroborators in order to confirm his results. Dr. Irving Glass carried out skin temperature and blood flow experiments, Dr. A. Wilbur Duryee provided consultations and analyses of data on these studies, and Dr. Martin Cohen performed rabbit eye tests. At this point, no results could be found within the documents on Killian's studies or those performed by "outside" corroborators. ~10 One document dated January 29, 1951 does mention "new irtformation Ul 04 brought to light by Dr. Killian, wherein he definitely shows that t'D ~ 89749536 cc - 5 - .!-
