| Description | Files making up this series were produced as a result of analytical, spectrographic and other work carried out in the Department's chemical laboratory. Members of staff kept their own notebooks in which they recorded data and made notes and sometimes sketches. Some volumes were kept in the laboratory while others were part of the working papers of the scientists concerned.
Most of the notebooks relate to chemical analysis of minerals, rocks and meteorites in some way, though others record spectrographic (DF19/19) and goniometric (DF19/13) data. A sub-series of volumes kept by Spencer, Hey and Sweet (DF19/10-12) relate to the alterations made to the register as a result of laboratory analyses. Included in the series are other papers which relate in some way to laboratory equipment, techniques and procedures. |
