| Description | A male technician is shown at a laboratory bench, working with a metal vessel which is being heated by a bunsen burner, a thermometer recording temperature. The technician manipulates a tube leading into the vessel. There is a corked and labelled specimen container on the bench, the label reading 'Heavy Mineral Oil A' and indistinctly dated, perhaps '22.2.1901' [?]. Taken at the Government Laboratories at Clement's Inn Passage, Strand, London.
