I noticed from the press releases from both 12thman.com and the Longhorn website that there is a discrepancy in the all-time head-to-head record. Texas listed it as 244-126-1 and A&M had it at 239-126-1. I compared the media guides for the both the Aggies and Longhorns and found that Texas has the following additional wins listed:
April 24, 1903 - Texas 6, A&M 2 in College Station
April 25, 1903 - Texas 7, A&M 1 in College Station
May 11, 1907 - Texas 7, A&M 3 at Austin
May 11, 1907 - Texas 2, A&M 1 at Austin
May 15, 1948 - Texas 3, A&M 2 at Austin
I did some digging and found the following:
1903 - A&M does not list the Aggies as fielding a team in 1903. The original team played in 1894, and then according to the media guide, the Aggies did not have a team until 1904. According to the 1903 Longhorn (http://bookreader.library.tamu.edu/book.php?id=yb1903&getbook=Go#page/n119/mode/2up), there was a team (official or club team I do not know) in 1903, and they were scheduled to play Texas in College Station on April 24th and 25th. I think the 1902 heading where the schedule is listed in the yearbook is a typo. I was not able to find a box score; The Daily Texan archives requires a $20 subscription to view, and the Cactus yearbook archives only go back to 1920.
1907 - These games did take place and unfortunately, the Aggies did lose both games. The Battalion includes write-ups and box scores for both in the May 15, 1907 issue.
1948 - This game did take place, and despite the efforts of Stan Hollmig the Aggies lost 3-2. The Battalion includes a write-up but not a box score in the May 17, 1948 issue.
