Some of the members now present were in this room a few weeks ago when Carl Hansen, a noted hypnotist from Denmark, induced in several persons a more or less marked degree of that condition known as hypnotism or Braidism, and we had the opportunity of making some experiments upon the subjects while in this state. Although the hypnotic phenomena were by no means so striking as is often the case, there were some interesting points elicited which, taken along with other experiments of a similar nature which I have witnessed before and since, will, I hope, form sufficient material for some considerations on the nature of the condition which is thus induced psychologically and physiologically, though I bring forward these remarks expecting to be enlightened myself in a delicate and difficult problem rather than hoping to enlighten those whom I have the honour to address to-night.
