Text-book of the embryology of man and mammals

Summary

A search for an official, unabridged audiobook of "Text-book of the embryology of man and mammals" by Oscar Hertwig on major platforms like Audible, Google Play Books, Apple Books, Kobo, OverDrive, Hoopla, and Libby did not yield any direct results. The search results primarily returned digital scans of the book itself, which is a historic text first published in 1901 (a translation of the third German edition) and is now in the public domain. Because this is an old, out-of-copyright scientific textbook, it is highly unlikely to have an official, commercially produced modern audiobook on standard retail platforms. No evidence of an official audiobook existence was found on the specified retailers.
