Страница 12 - A thrilling, extending from the chest to the extremities, was almost immediately produced. I felt a sense of tangible extension highly pleasurable in every limb; my visible impressions were dazzling, and apparently magnified...
Страница 40 - The civilized man overburdened with mental labor, or with engrossing care, seeks the same shade; but it is shade, after all, in which, in exact proportion as he seeks it, the seeker retires from perfect natural life. To search for force in alcohol is, to my mind, equivalent to the act of seeking for the sun in subterranean gloom until all is night.
Страница 13 - I imagined that I made discoveries. When I was awakened from this semi-delirious trance by Dr. Kinglake, who took the bag from my mouth, indignation and pride were the first feelings produced by the sight of the persons about me.

We may then, I think, fairly assume that in course of time we shall discover manageable and certain anaesthetic substances which will paralyze sensation only, leaving the muscular power unaltered and the mental...
Страница 13 - By degrees, as the pleasurable sensations increased, I lost all connection with external things ; trains of vivid visible images rapidly passed through my mind, and w^ere connected with words in such a manner, as to produce perceptions perfectly novel. I existed in a world of newly-connected and newlymodified ideas.
Страница 40 - Speaking honestly, I cannot by any argument yet presented to me, admit the alcohols through any gate that might distinguish them as separate from other chemical bodies. I can no more accept them as foods than I can chloroform, or ether, or methylal. That they produce a temporary excitement is true, but as their general action is quickly to reduce animal heat, I cannot see how they can supply animal force.
Страница 40 - ... as their general action is quickly to reduce animal heat, I cannot see how they can supply animal force. I see clearly how they reduce animal power, and can show a reason for using them in order to stop physical...
