Actually, a lot of nouns and other words are capitalized in the US Constitution that we don't normally capitalize today. I don't know what the style is called, for that.
I just call it archaic, and it's typical of the writing of the day. I kind of get a kick out of it and occasionally do it myself.
I wonder, does anybody dots i's and j's when they write or print? I can't remember ever actually doing that, except maybe in early grade school.
I have always dotted my i's and j's. To be honest I don't think I've seen someone not
do it. The dots are so integral to those letters!
