There was a certain nervous haste and restlessness in all his movements which had never before characterized them, and a like feverish excitableness was to be remarked in his voice and manner, as in the course of conversation he passed from one subject to another, never pursuing any for more than a few minutes.
"Fickle Fortune"
Elisabeth Burstenbinder (AKA E. Werner)
The half-breed had not much excitableness in his nature, but when he saw this beautiful woman with a touch of the Indian in her contour, his pale face flushed, and he showed his set teeth under his slight moustache.
"Pierre And His People, [Tales of the Far North], Volume 4."
Gilbert Parker
All this excitableness and irritability of temper was at the bottom nothing but disease, as the event proved; for four months ago, I believe you know, he fell into a violent nervous fever, and was so ill that every one gave him up.
