First Edition, Offprint Issue. "Swiss born embryologist Wilhelm His, Sr. (1831-1904) was the first scientist to study embryos using paraffin histology, serial sectioning and three dimensional modelling. With these techniques, His made many important discoveries in vertebrate embryology and developmental neurobiology, earning him two Nobel Prize nominations. He also developed several theories of mechanical and evolutionary developmental biology" (Richardson & Keuck). His's studies of the chicken embryo (Hühnerembryo) in the 1860s and 1870s established his reputation as an embryologist. One of his goals during this time was to establish an exact topography of the chicken embryonic disc, as described in the present paper.
