Pulmonary vessels of excised rabbit lungs were injected with a suspension of barium sulfate in gelatin. Slices 50 I\*. thick were radiographed at 5 kv and 2 ma using high resolution spectroscopic plates. When these plates were viewed through a microscclpe, pulmonary arterioles, venules and capillari

β¦ Synopsis
Conventional radiographs of lungs of calves which had been injected post mortem with barium sulphate could not be used to demonstrate vessels smaller than 50 ,u in diameter. To overcome this difficulty, frozen sections 50-150 fi thick were floated on to high resolution photographic plates and contact microradiographs made using soft radiation. The resultant microradiogram was then viewed and photo- graphed with the light microscope. It was possible to visualize the smaller arterioles and the capillary networks around the alveoli. The technique is simple and gives reproducible results.
