Section of Bone
A small piece of bone, ground very thin and highly magnified. “If a bit of bone is still more magnified we find that very small cavities called lacunae lie between the lamelae; from each lacuna radiate many extremely fine tubes, the canaliculi, so that it looks like a small animal with a great many legs. The innermost canaliculi open into the Haversian canal of the system to which they belong, and those of various lacunae communicate with one another, so that a set of passages is provided through which liquid which transudes from the blood vessel in the Haversian canal can ooze through the bone.” —Newell, 1900.
