The act of the holder of an instrument in retracing words therein which have become defaced or illegible, does not amount to an alteration,1 since such retracing is not done with the intention to alter the instrument,2 and since the legal effect is not altered if the prior words are correctly retraced. The act of the holder in retracing the signature of the maker, is not an alteration,3 even if in such retracing a name is spelled incorrectly,4 at least if the name, as erroneously spelled, is substantially the same as the true name of the party.5
