Which highly poisonous substance was once known as prussic acid?
Lythalls Lane Stadium an inauspicious start when the General and Racing Manager Lieutenant-Colonel Geoffrey Nigel Fitzjohn committed suicide in the stadium offices in 1929. The 47 year old took a dose of prussic acid, a highly poisonous substance. Then in early 1933 the main stand caught fire and was destroyed.

Lythalls Lane was located in a mainly a rural area during the war which luckily resulted in minimal damage during the Coventry Blitz in 1940 and 1941.

Isocyanic acid Isocyanic acid Isocyanic acid is a chemical compound with the formula HNCO, discovered in 1830 by Liebig and Wöhler. This colourless substance is volatile and poisonous, with a boiling point of 23.5 °C. Isocyanic acid is the simplest stable chemical compound that contains carbon, hydrogen, nitrogen, and oxygen, the four most commonly found elements in organic chemistry and biology. Isocyanic acid can be made by protonation of the cyanate anion, such as from salts like potassium cyanate, by either gaseous hydrogen chloride or acids such as oxalic acid. HNCO also can be made by the high-temperature thermal decomposition of cyanuric
