The only animals in which the upper process of the scapula exists

At the same time I wish all to know that I have never encountered any animal possessing this process of the upper scapula except man, ape, squirrel, and, if I remember rightly, the dormouse. I therefore have no doubt that whoever first wrote that only man possesses an acromion understood that man alone had this process; when he saw no upper process of the scapula (but only the spine) in dogs, 83 sheep, goats, rabbits (which indeed have only the inner process of the scapula) and other quadrupeds that are served as food, he did not bother with apes, as Galen did. We may therefore call this upper process of the scapula summus humerus or “the upper process” until a more correct view comes to light. 84
