Thomas Nuttall Correspondence To John Bachman

Correspondence from English botanist and zoologist Thomas Nuttall (1786-1859) to American naturalist Reverend John Bachman (1790-1874), dated January 17, 1837, his failure to procure an intact specimen of Lepus (Lagomys) princeps (now called Ochotona princeps, or American pika) and expeditions to the Colorado, Missouri, and Columbia Rivers, which yielded no findings of animal species "larger than a mole," he wrote.
