Theoria generationis.

Halle: lit. Hendelianis, 1759.

Wolff observed in great detail the early processes of embryonic differentiation. He disposed of the “preformation” theory, substituting his view that the organs are formed from leaf-like (blastodermic) layers. He thus laid the foundation of the “germ-layer” theory of Baer and Pander. His book includes descriptions of the “Wolffian bodies” and “ducts”. Reprinted 1966.

De formatione intestinorum praecipue.

Novi Comment. Acad. Sci. Petropol., 12, 43-7, 403-507; 1769, 13, 478-530, 1768.

One of the acknowledged classics of embryology. Wolff’s description of the formation of the chick’s intestine by the rolling inwards of a leaf-like layer of the blastoderm was important as proving his theory of epigenesis. A German translation by J. F. Meckel was published in 1812.
