"The platypus" by Harry Burrell is a natural history monograph written in the early 20th century. It presents a comprehensive, field-based account of the animal’s discovery, classification debates, anatomy, senses, habits, reproduction, nesting, range, captivity, and conservation, supported by photographs and plates.

The opening of this monograph sets out Burrell’s approach and scope: nearly twenty years of first-hand observation, reliance on living or fresh specimens, and illustrations left untouched, with the work aimed at general readers. It then traces the animal’s entry into science—early skins sent to Britain, Shaw’s 1799 description and doubts, and the swift eruption of controversies over what the creature was and how it reproduced. Burrell summarizes the long dispute about its zoological position (from “new tribe” or separate class to a mammalian sub-class) and the parallel egg-laying debate, including misreports, misidentified “eggs,” and strong opposing claims, before noting Caldwell’s late confirmation of oviparity. He contrasts fanciful or secondhand tales with the scarcity of early local accounts, and situates monotremes as primitive yet highly specialized survivors. The narrative then sketches key external features linked to life in water—webbed forepaws, a flattened tail, and especially the soft, ultra-sensitive bill used for underwater foraging with eyes and ears closed—alongside observations on eyelid–ear closures, clumsy terrestrial gait, horny grinding plates, cheek-pouches likely used to carry grit for mastication, and a sensory skin flap. The section closes by recounting first European encounters near the Hawkesbury, the spread of specimens through British and French hands, and a concise review of the major scientific arguments that shaped early understanding.
