Helium
Please don't to Wikipedia, particularly to featured articles, and especially when it's wrong. http://articles.adsabs.harvard.edu/full/1921ApJ....53..233C makes it clear that Lockyer installed a large dispersion spectrometer at his home in West Hampstead in October 1868 in order to make observations of the spectral lines. He wasn't in India until 1871. --RexxS (talk) 18:23, 10 March 2016 (UTC)

Sorry for telling you that the helium day celebrated every year in the old fortrest in india is based on a wrong concept.--Stone (talk) 20:32, 10 March 2016 (UTC)
