Physics C like Chemistry I is a course supposed to be either three hours lectures or two hours of lectures and four hours of laboratory work. In Chemistry I this rule is carefully observed and when a third lecture or recitation is given, the laboratory work is cut down two hours that week. In Physics C the instructor now proposes to give three lectures per week without however, cutting down the laboratory work required. It is true that he makes attendance at the third lecture optional, but he intends to give an hour examination covering the work of the third lecture so that the nominal permission to be absent becomes farcical if one wishes to get a good mark in the course, thought this last is almost impossible to attain under any circumstances owing to the severe and erratic system of marking in vogue.
