Hyponitrous acid is formed by passing nitrous fumes into its methyl alcohol solution.
An instant before, Stubb had swiftly caught two additional turns with it round the loggerhead, whence, by reason of its increased rapid circlings, a hempen blue smoke now jetted up and mingled with the steady fumes from his pipe.
