How does Lanyon react when Hyde touches him in Chapter 9 ?

Lanyon recoils from Hyde's touch. From the text:

I put him back, conscious at his touch of a certain icy pang along my blood. "Come, sir," said I. "You forget that I have not yet the pleasure of your acquaintance. Be seated, if you please." And I showed him an example, and sat down myself in my customary seat and with as fair an imitation of my ordinary manner to a patient, as the lateness of the hour, the nature of my pre-occupations, and the horror I had of my visitor, would suffer me to muster.
