COMPARATIVE MAMMALIAN ANATOMY - 1860
Benjamin Waterhouse Hawkins
A comparative view of the human and animal frame
Chapman and Hall, 1860
Ten plates with brief explanatory text intended 'to give a comparative view of the variation in form of the bony skeleton or framework of those animals most frequently required by the artist, designer, or ornamentist.”
It appears that Waterhouse Hawkins, who is best known for his work with dinosaurs (here and here), wanted to make the illustrations as realistic as possible. All are depicted next to Homo sapiens, who is posed in ways the illustrator apparently felt were natural: a man leads a horse, gives a treat to his camel, shows off his elephant, and [perhaps] supplicates a king attended by the king of beasts.
The textual explanations of variation in animal form did not yet reflect the influence of Charles Darwin’s evolutionary theory, but the detailed illustrations added much to the understanding of mammalian anatomy.
