Linotype is newfangled printing technology. I have a Job Press that is powered by a foot peddle and the type is set letter by letter. The terms we use today, “upper case and lower case” originated in the old print shop. The capital letters were in a tray on the upper rack of the type case, and the regular letters were in a tray on the lower level of the type case.
It was 7 pair of ”clean animals” and one pair of ”unclean animals.“ Also 7 pair of every kind of bird.
