Walls of the Abdomen.  — The muscular walls of the abdomen are nicely arranged and beautifully adapted to the functions they perform.  On the left side we see the large oblique muscle, so named because of the direction it’s fibres run, and on the right side we observe the rectus muscle, transverse muscle and internal oblique muscle, all of which are strong, broad muscles, will split manner in which they are so scientifically arranged gives additional string to the abdominal walls, without deteriorating from its great mobility, and at the same time avoiding all pressure of the organs contained within this large cavity.  There are ninety-one muscles on each side of the trunk, or one hundred and eighty-two in all, ninety of which are pairs, and two are single.

I noted a slight difference in spelling for the word “fibres” in the section.  I’m not certain if this is a medical spelling or if it’s just a difference in spelling that’s evolved over the last 90 years.  In addition the section also has a reference again to the beauty and perfection of design which doesn’t overdo it too much in this particular paragraph but given the history of the book so far seems to have more of a enthralled tone than you might expect.
