*916OPINION.
Phillips:The first assignment of error was waived at the hearing.
There is no merit in the second error assigned.

Before the expiration of that period respondent mailed his deficiency letter, and within 60 days after the mailing of that letter petitioner filed its petition with the Board.
The third assignment of error must be decided adversely to petitioner on the authority of Russel Wheel & Foundry Co., 3 B. T. A. 1168.
Decision will he entered for the respondent.
