17. “ Merely to say, that each object of my Illustrations is of the size of nature, were too vague – for to many it might only convey the idea that they are so, more or less, according as the eye of the delineator may have been more or less correct in measurement simply obtained through that medium; and of avoiding error in this respect I am particularly desirous. Not only is every object as a whole, of the natural size, but also every portion of each object. The compass aided me in its delineation, regulated and corrected each part…. The bill, the feet, the legs, the claws, the very feathers as they project one beyond another, have been accurately measured.”
