That is not in the written majority opinion by Justice Gray.
Hmmmmm.....
I've got a hardcopy of the case, U.S. v. Wong Kim Ark, 169 U.S. 649(1898) in my hands, 33 pages of about font size 6 print, but I have this statement below is highlighted on page 2.
Verbatim. "Mr Justice GRAY, after stating the facts in the foregoing language, delivered the opinion of the court."
Scratching head.... :-0)
