This is a black and white illustration of a transverse section of human scalp, likely a microscopic view. The image is densely packed with circular structures, which are hair follicles. Each follicle appears as a dark, rounded shape with a central core. Surrounding each follicle is a lighter, fibrous tissue that forms a network throughout the image. The tissue appears to be composed of interwoven lines and strands, creating a complex pattern. The overall impression is one of intricate biological structure, typical of a scientific illustration. Below the image, there is text identifying it as 'FIG. 46. TRANSVERSE SECTION OF HUMAN SCALP. x 100.' and a reference to page 149.
