The image is a vintage illustration of a nettle sting, likely from a botanical or scientific text. It's a detailed drawing of a single nettle hair (or stinging trichome) magnified 55x. The hair is depicted as a slender, elongated structure with a bulbous, almost teardrop-shaped head. The head appears to be filled with a darker substance, suggesting the presence of the stinging fluid. The shaft of the hair is slightly thicker at the base and tapers towards the tip. The base of the hair is embedded in what appears to be a leaf or stem surface, indicated by a rough, textured area. The illustration is rendered in a detailed, cross-hatched style, typical of scientific illustrations from the late 19th or early 20th century. The background is a creamy, off-white color. Below the illustration, there is text identifying it as “FIG. 36. STING OF NETTLE.” and magnification level “x 55”. A note at the bottom right reads “[to face page 123.]”.
