Geographical Division & Distribution of Carnivora by A.K. Johnston, engraved by W. & A.K. Johnston and published by William Blackwood & Sons in Edinburgh and London in 1857, presents a systematic representation of the distribution of Ruminating and Gnawing Animals on two separate maps.
This map comes from a period of notable exploration and scientific classification, reflecting a methodical approach to zoological study. The shading technique provides an objective method to understand the presence of species in different provinces.
The map also includes two sets of engraved illustrations of different Ruminating and Gnawing Animals on the various continents.
