Robert W. Henry, College ofVeterinary Medicine, The University of Tennessee,Knoxville, TN, USA.Air-dried lungs at room temperature wereimpregnated with a mixture of S10/S3 (polymer-mix)and xylene. Compressed air from the laboratorybench was used to propel the polymer-xylene mixfrom the air ways into the parenchyma of the lungtissue and on through to the surface of the lung.The lungs were dried using air from the laboratory airsupply line. Mixtures of xylene and S10/S3, whichvaried from 15% to 45%, were forced into lungs, toimpregnate the lungs with silicone, via forced airrather than using dehydration and vacuum. Thetrachea was cannulated and the lungs positionedsuch that one-half of the polymer-xylene mix waspoured into the left portion of the airway and theother half of the mix into the right portion of theairway. Laboratory air (dried medical air), at a highvelocity and pressure (30 - 50 Ibs/sq. in.), was
