Abstract
THE interesting discussion on this subject in your columns has hitherto been almost entirely confined to facts of extraordinary “perception” with mammalia. But in-other classes of the animal kingdom there occur instances perhaps even more astonishing still, showing a power of perception which we needs must attribute to smell, unless we are inclined to talk about natural forces hitherto unknown, to which I should prefer saying that we do not yet understand the matter at all.
