7 micrographs showing the results of chick limb transplantation
4 black and white photographs of chick limb bud development. Stage 29. The limb buds have been removed from the embryo and are placed on a black background. The image on the top left is of only a wing bud at stage 29.
Plate XIX from Edmund Beecher Wilson's "The Cell-Lineage of Nereis" in the Journal of Morphology, Vol. 6, 1892. The plate shows 12 images of various stages of Nereis embryos with labelled cells.
10 black and white photographs of transverse sections through various stages of chick embryos. The bright white oval in the center of each section is the central canal of the developing chick's neural tube. The photographs are arranged so that dorsal is up.
Three black and white photos of cells. The photos have been labelled along the side with times (2:40, 2:45, 2:50), and several cells in each have been marked with a red dot.
13 black and white photographs of different stages of chick limb bud development. The limb buds have been removed from the embryo and are placed on a black background. Stages 23 through 35 are pictured. Wing buds are pictured on top, leg buds on the bottom.
Two black and white photos of different sides of an embryo. The right photo is labelled "left side neutral" and the left photo is labelled "right side shield".
15 hand drawn sketches in pencil of exogastrule. Sketches are labelled in ink: 23 through 35b, and notes in ink accompany
4 black and white photographs of different stages of chick development (whole embryos). Stages 12, 13, 14, and 22 are shown.
Plate III from Edwin Grant Conklin's "The Embryology of Crepidula" in the Journal of Morphology, Vol. 13, 1897. The plate shows 12 images of various stages of Crepidula embryos with labelled cells.
13 hand drawn sketches in pencil of exogastrulae. Sketches labelled in ink: 13 through 26.
Hand drawn sketch of chick embryo (4.5 days incubation) and the development of the wing and limb buds. Also hand written notes about the stage of the embryo and the differences between it and other stages.
