Physical Laboratory. According to the general catalogs, the Laboratory was called the Chemical Laboratory from the 1863-1864 school year through the 1869-1870 year.    The laboratory was called the Physical Science Laboratory from 1870-1871 through 1887-1888. The 1888-1889 Catalog lists the laboratory as both the Physical Science Laboratory and the Chemistry Laboratory. Both of these departments were located in North Hall at that time, and perhaps the terms were used interchangeably. After 1890 however, the Chemical Laboratory was housed in the new Chemical Laboratory Building, while the Physical Science Laboratory remained in North Hall. Therefore, all papers relating to either of these laboratories prior to 1890 (when the Chemical Laboratory was constructed), are filed under Physical Science. Laboratory. Papers dated after 1890 are filed under Chemical Laboratory, unless they clearly relate to Physics., Sub- 16, Folder: 736.
