(Chapter 23) Footnote 30:

Beginning after this point another large portion, nearly twenty lines of the 1543 version, was recast down to the paragraph describing the middle parts of the humerus. Most notably, the 1555 edition deleted the criticism of Aristotle and the reference to Erasmus. The rewritten part runs as follows: “Nonetheless, if you consider the humerus of simians, and still more of dogs and other quadrupeds besides (which have a very thick radius that is not mobile against a very slender ulna) you will find Galen’s opinion fits it much better than it fits the human humerus. The humerus, to describe its middle region as well, is rather smoothly rounded along its length.”
