As I investigate the use of tree diagrams in the nineteenth century, I keep running across things that shouldn’t be there. One of them was this book:
Herdman, William Abbott. 1885. A Phylogenetic Classification of Animals (For the Use of Students). London; Liverpool: Macmillan & Co.; Adam Holden.
It’s on Archive.org, but they didn’t properly scan the figure on the foldout (a real problem of the electronic versions of old books is that they don’t scan the foldout figures. Imagine the Origin without the one figure). So I bought a copy. It’s a real revelation – he correctly uses “polyphyletic” in its modern sense on page 2. So below the fold is the figure and the caption, with a link to a larger version to download.
Of interest is that Herdman is mixing phylogeny with grades – the vertical axis represents “advance in structure”, whatever that might mean. It’s not cladism yet…




wow.
It’s engrossing, like an old map.

Wow! 1885!

It is truly an incredible find. If you had just posted the reference, I would have thought the 1885 date was mistyped from 1985. The downward slope to indicate degeneration is a nice touch.
You bought yourself a copy? A facsimile?
