晨雾50°，房中56°。下午房中64°。苹果花渐落，
北京晨雾500 ，房中560 。下午房中640 。苹果花渐落，
院中白丁香花落满地。
中午约张宗麟、邓艾宗、钱三强、慕光在维尔康中膳。
晨六点起。八点至院。阅俄文…小时。觉倦极欲睡。十点与三强、简焊坡谈教育部在大学办研究所与科学院之研究所如何合作问题。据云有清华若干助教以为研究所之研究生应与科学院有别， 此种分工殊为困难。茅唐臣来，为其女茅于燕事，欲先人图书馆，后转往心理研究所。
十一点张宗麟来，与谈教育部所属各大学与科学院研究分工问题。渠意欲二机关分工，大学研究院多注意养成大学之讲师教员，而科学院则为解决研究问题。
谈论长久， 并邀悻子强、严慕光、钱三强与张宗麟、邓艾宗同谈。至十二点半，乃往王府大街威尔康中膳，四菜一汤，不吃酒，费五万五千元(每人一万一千元)。余告张宗麟，谓要把大学研究院办好，必须有视察之组织，去审查何大学可以办研究院，办得好不好亦须时时察勘。但张宗麟颇多顾忌，以为设立专家，则不被聘为专家者将生怨云云。二点回院。四点至南锣鼓巷4 1 号晤饶树人，知其巳移至那芝府〔乃兹府〕之北大宿舍。回。洗浴。
