At the atmospheric temperature the contraction orthe affected side lasted 315 sec (Tracing IX). Jr 1 ^—-^ ^ d3,7S After appHcation of heat the contraction lasted 2*4-3 sec. (Tracing X). After a short apphcation of cold by immersion in waterat 12° C, the extent of the contraction on the affected sidewas too feeble to be recorded. On the sound side the amphtude of the contraction wasalso too feeble to be recorded. 552 REFLEX NERVOUS DISORDERS. Tracing X (Paralysis with Reaction of Degeneration, Case III).—After application of heat by immersion of the two hands in waterat 44° C, the contraction lasts 2-4 sec. on the affected side. The graphic method, therefore; confirms the resultof numerous clinical investigations; it shows thatthe slowness of the muscular contraction caused bypercussion may be as marked in reflex contracturesand pareses as in many cases of paralysis with reactionof degeneration. The intensity of the muscularhyperexcitability and slowness of the contractionare in proportion to the vaso-motor and thermal dis-orders ; when there is considerable hypothermia, itmay almost be asserted a priori that the mechanicalexcitability of the muscle is exaggerated and that themuscular contraction is slow. But what relation is there between vaso-motor andthermal disorders, on the one hand, and disturbancesof voluntary movement on the other ? There is un-doubtedly a connection between the two cl
