Is this the game you are talking about? Because it is the one in the YouTube link but it doesn't seem to match the text you posted:
Morphy blunder found in the A First book of Morphy, by Frisco del Rosario?
I also looked into this a little and found that the youtube game and its source is wrong. I think the game Martin posted has the correct moves.
Check this link for the game and a little discussion of the move errors.

edit: ... but your analysis is correct
<a href=http://zapodaj.net/82434f42d26dd.png.html>chess.png</a> picture after black move Nc6, my version of a book state the same. Maybe there were editing problem and some variations were mistakenly printed.

It's true. Nc6 was a blunder - followed by a reciprocal blunder by Barnes.
According to my database, Barnes scored 3 1/2 points out of 9 against Morphy (3 wins, 1 draw, 5 losses) so he was a talented player.

Read the comments to the link Gomer_Pyle gave. The original printings of the game score match the game I posted above. That blunder didn't happen but some databases have the incorrect score, which apparently made into some books.
Here is the score, published in The Chess Monthly, September 1858, as referrenced in the link above.
Hi Everyone
It is rather unlikely to find out that one of chess god's Mr. Paul Morphy made a big mistake in a game, analyzed and approved by Frisco del Rosario in his book A first book of Morphy.
The game between Thomas Barnes (white) and Paul Morphy (black) played in London 1858. The opening: Philidor Counter Gambit.
Link to the game: http://www.youtube.com/watch?v=Iif7sgPUhE8
The tactical blunder was made on the move 12. Black played Nc6, and for that move the best seems to be Qh5.
"The Chessmaster recommends: Queen to h5.
Analysis: You move your queen to h5, which removes the threat on your pawn at h2 and triple-forks Black's pawn at h7, Black's bishop at c5, and Black's king. Black responds by moving the king to d8, which moves it out of check. Your queen captures bishop, which threatens mate (queen to f8). Black answers with queen to f3, which blocks your pawn at f2. You move your knight to d2, which attacks Black's queen. Black answers with queen to f4, which moves it to safety and attacks your pawn at h2. You castle. Black counters by moving the knight at g8 to e7, which blocks your pawn at e6. You move your queen to h5, which protects your pawn at h2 and attacks Black's pawn at h7. Black answers with pawn to g6, which threatens your queen. You move your knight to f7, which protects your queen and checks Black's king. Black responds by moving the king to e8, which moves it out of check and attacks your queen. Your queen takes pawn at h7, which isolates Black's pawn at g6.
As a result of this line of play, you win a bishop and a pawn. Additionally, the mobility of your pieces is greatly enhanced, and Black's mobility is lessened. Also, Black's pawn formation is somewhat disrupted. Finally, the pressure on Black's King is somewhat increased, and the pressure on your King is slightly decreased."
As an instructional game for opening rule no. 9 this seems pretty big for me. How is that possible that annotator made this big mistake of putting blundered game as an instructional one in his book?
