Zoological Geography. The Geographical Division and Distribution of Mammiferous Animals of the orders: Quadrumana, Marspialia, Edentata and Pachydermata by Johnston, Alexander Keith.

Alexander Keith Johnston, a central figure in 19th-century scientific cartography, was acclaimed for his thematic atlases that visualized complex natural systems with precision and clarity. Working during a time of rapid scientific discovery, he collaborated with leading thinkers to integrate contemporary knowledge into maps that served both educational and exploratory purposes. His work remains a testament to Victorian efforts to catalogue and comprehend the natural world through geographic lenses.

Zoological Geography: The Geographical Division and Distribution of Mammiferous Animals of the Orders: Quadrumana, Marsupialia, Edentata and Pachydermata is a richly detailed thematic map from Johnston’s Physical Atlas. Created in the 1850s, it charts the global habitats of primates, marsupials, sloths and anteaters, and large herbivores like elephants and rhinos. Each group’s distribution is mapped to reflect early understandings of ecological niches and continental uniqueness. The map reveals the Victorian drive to classify life on Earth geographically, predating evolutionary theory yet laying the groundwork for modern biogeography.
