The higher average values found by Arango and Rowe immediately after catheterization of the aorta under local anesthesia may be explained by excitement (41) in 10% formialin, sectioned transversely across the long axis, and cut perpendicular to the surface. Microscopic sectionis were photographed at the highest magnification that allowed the complete thickness of the cortex to be included in the picture.…”
