Having turned up his coat-cuffs , he commenced the application of the Cyanochaitanthropopoion , rubbing it into his hair , eyebrows , and whiskers , with all the energy he was capable of , for upwards of half an hour . Then he read over again every syllable on the papers in which the bottle had been wrapped ; and about eleven o'clock , having given sundry curious glances at the glass , got into bed , full of exciting hopes and delightful anxieties concerning the success of the great experiment he was trying . He could not sleep for several hours .
