Twaalf vergrotingen van beenmerg before 1882

"Twaalf vergrotingen van beenmerg" is a collection of twelve photomicrographs of bone marrow from a fowl, created by Richard Norris before 1882. These images depict various stages of bone marrow development, showcasing the formation of ellipsoids, granular pigment cells, and red corpuscles. The detailed descriptions accompanying the images offer insights into the microscopic world of bone marrow, illustrating the intricate processes of cell differentiation and growth. This work is a valuable resource for researchers and those interested in the microscopic anatomy of birds.
