A comma is expected in the 1st blot in line 7: the Barnes blot. The FBI teletypists used commas freely. Lines that intersect inside said blot indicate barely enough area at the end of the blot to blot out a comma. The solitary vertical shows columnwise comma positioning. But the FBI typist might've mistyped and failed to put the expected/needed comma on paper. This is what probably occurred in line 5 after "JAN FIFTEENTH," where a comma is grammatically correct/expected, but is not on paper: what is on paper is an anomalous double-space which does not follow a period.
