Even as we headed into the 19th century, his theories were being expanded upon and referenced. L.A. Vaught was a big proponent of `Phrenology` releasing a book titled `Vaughts Practical Character Reader` in 1902.
Within the book are countless diagrams, each attempting to categorize different areas of the brain and the impact they have. A mishmash of illustrated psychiatry, neuroscience and mindless babble.

"We emphatically advise women to distinctly bear in mind that all men with heads shaped like this are unreliable as fathers"
