It looks like the wall in question is retaining soil. It also looks like you're putting in new openings. The dead load on the wall is likely the only thing keeping the wall stable. Are you concerned at all about changing the nature of the loading on this wall?

Not adding any new openings, had to cut down the top of wall for a mudroom addition. New foundation walls will go down to bottom of existing footing so no new pressures will be added to wall.

They have a book that may also be useful; "Handbook of Hollow Building Tile Construction" from 1922. I tried to upload it but apparently it's too large a file.
