Historia Naturalis Ranarum,
Author: RÖSEL VON ROSENHOF, August Johann (1705-1759)
One of the most beautiful natural history books ever produced and the finest devoted to frogs and toads. The plates illustrate their internal anatomy, embryological development, skeleton, habitats, etc. There are amazingly accurate renderings of dissected specimens carefully mounted for anatomical study. The hand-coloured frontispiece is engraved by Martin Tyroff after the author’s drawing.
