Reference 3 is at the bottom of page 20 in the original,
Reference 5 is at the top of page 23, I cannot find
Reference 4 anywhere.
Spelling errors are denoted by [correct_spelling sic]. Most of these are just variants and currently archaic terms, but some appear to be actual errors. Correct version is from my on line dictionary, or when in doubt, from my printed Collegiate Dictionary. This is also used when, IMHO, there is an error in the text.
The index is not included, as the pagination used in it is
irrelevant.
The duplication of reference [36], ([36],[37],[36],[38]) in
chapter 4 is in the original.
There are many places (see especially chapter 6) where an unbalanced right square bracket appears, often after either an italicized phrase or a Hebrew phrase. These are in the original.
