On a new compound of chlorine and carbon [PDF]

open access: yesAbstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London
Abstract The above substance was discovered by M. Julien, of Abo, in Finland, amongst the products arising out of the distillation of calcined sulphate of iron, with crude nitre in iron retorts. It forms white acicular crystals by sublimation, and when passed through a green glass tube containing red-hot rock crystal, it is decomposed
