The Practical Problems of ‘New’ Experimental Science: Spectro-Chemistry and the Search for Hitherto Unknown Chemical Elements in Britain 1860–1869
Published online by Cambridge University Press: 05 January 2009
Extract
On the morning of Friday the fourth of December 1863, August Hofmann, professor of chemistry at the Royal College of Chemistry in London, lectured at the College on spectro-chemical analysis to Victoria, the Princess Royal, Princess of Prussia and eldest daughter of the Queen and the severely missed late Prince Consort. This event illustrates the spectacular success that the fledgling science of spectro-chemical analysis enjoyed during the 1860s.

39 For example, on 28 March 1861 McLeod visited three instrument makers in search of a suitable spectroscope which could be constructed. However, it was not until 27 May 1861 that he placed an order with Slater. There then followed a good number of visits, adjustments, additions etc., so that it was not until 1 August 1861 that McLeod could declare that ‘It did splendidly’.
