The names of all Freshmen who, unless excused on account of sickness, have not filled out their course of study blanks in time to reach Professor C. P. Parker, the chairman of the Committee on Choice of Electives, by the first mail this morning, will be handed to Assistant Dean Castle and each man will be summoned for an explanation. It is likely, however, that three days of grace will be given to men with a reasonable excuse. Any man failing to hand in the blank before 5 o'clock Thursday afternoon will be placed on probation, unless he has been prevented from doing so by sickness.
