Respiration very free, as if the thorax were hollow, in the afternoon (2nd day).
Heart and Pulse.
The heart began to tremble, with a rumbling noise, and I was unable to distinguish the pulsations; this lasted one hour, after which the beat of the heart and pulse (the latter could not be felt on the left side) became irregular, and numbered 200 per minute (soon after 8 o’clock, morning after triturating). Palpitation, noticed on leaning against the back (2nd day). Sensation as if the heart had stopped still; no perception of the beating of the heart; after 1 P.M. (2nd day). The beat of the heart became regular toward noon; pulse, felt in the temples and at radial artery, 200 (pulse usually 76). Back. In the “solar plexus’ a pressure (usually felt only after eating tough meat or hard nuts, of which I had not now partaken) extended toward the back, where it changed to a pinching sensation; spine painfully sensitive to touch at this point (2nd day).
Painful weariness felt in shoulder and elbow-joints (2nd day).
