(Chapter 24) Footnote 64:

The end of the chapter is rewritten from this point as follows: “Except for the small foramina that provide origins for nerves and muscles, the radius and ulna have no foramina worthy of note. They are everywhere of a solid and quite hard material except where they have epiphyses, though they have a cavity carved lengthwise inside as do the humerus, femur, and tibia, provided to contain marrow and contributing to the lightness of the bones.”
