The strontia flame exhibits a great number of red rays well separated from each other by dark intervals, not to mention an orange and a very definite bright blue ray. The lithia exhibits one single red ray. Hence I hesitate not to say that optical analysis... Handbuch der Spectroscopie - Page 20by Heinrich Kayser - 1900Full view - About this book
