“Now if we place the first, -- cyanuric acid, -- in a vessel hermetically sealed, and apply a high degree of heat, it is converted by its influence into hydrated cyanic acid; and, then, if this is kept for some time at the common temperature, it passes into cyamelide, no other element being present.”
“And, again inversely, cyamelide can be converted into cyanuric acid and hydrated cyanic acid.”
“In cyanuric acid, hydrated cyanic acid, and cyamelide, we have three such isomeric compounds.”
