Ward was now visibly aged and hardened, but was still normal in his general reactions; and in several talks with Willett displayed a balance which no madman⁠—even an incipient one⁠—could feign continuously for long. What elicited the notion of insanity at this period were the sounds heard at all hours from Ward’s attic laboratory, in which he kept himself most of the time. There were chantings and repetitions, and thunderous declamations in uncanny rhythms; and although these sounds were always in Ward’s own voice, there was something in the quality of that voice and in the accents of the formulae it pronounced, which could not but chill the blood of every hearer. It was noticed that Nig, the venerable and beloved black cat of the household, bristled and arched his back perceptibly when certain of the tones were heard.
