 damp case at 30° Cels. 



3.30 p.m. Rigor mortis in Die left hip. 



4 30. Left hind-fool is enlircly slilTened, only I he fool is slill a lillle 

 movable. The right hind-leg is slill (|uile supple. Bolh fore-legs are slilf.

11 Fehr. 9.80. Hung in damp case at 30° Cels. 



11.30. Right hind leg with expanded webs, when lifting it the right leg 

 shows increased resistance. Left hind-leg still quite supple. 

 1 p.m. Right hip rather stiff, left one still quite supple. 



3 p.m. Right hip rather stiff, right knee drawn up. Left hind-leg still 

 quite supple. 



5 p m. Right hip entirely, knee- and foot-joint partly stiff, much increased 

 flexion position to the right. Left hind-leg still quite supple, the webs are 

 here expanded. 



5.30. Right hind-leg stilf in flexion-position, only the foot-joint is paitly 

 stiff; left hind-leg is still supple in all joints. Bolh fore-legs stiffened. Frog 

 is now placed in a surrounding of 15^ Cels. 



12 Febr. 9 a.m. Situation still exactly the same as last night at 5.30. 

 From this moment temperature at 30° Cels. 



12 at noon. Lett himl-leg begins to become stiff in knee and hip ; right 

 foot-joint still partly stiff. 



J. 30 p.m. Right hind-leg also' stiffened in the foot-joint, entire tense- 

 position ; left hind-leg in tense position stiff in knee and hip, left foot is 

 slill partly supple. 

 Va. 12 Febr. 9.45 a.m. Right dorsal root 8, 9, and 10 cut through. 



10 p.m. The frog is hung in the damp case at 30° Cels. 



1 p m. The left leg begins to draw up, the flexion in the hip and the 

 dorsal flexion of the foot increase. 



2 p.m. Left hip strongly flexed ; left foot strongly dorsally flexed, on the 

 left side increased resistance when lifting. Right leg still su{)ple. 



4 p.m. Left hip entirely stiff, knee and foot begin to be stiffened. Right 

 hind-leg begins to draw up. 



6 p.m Right hip and knee now likewise partly stiff, foot is slill supple. 

 Left hind-leg in tense position with slill partly süp|)le foot, right hind-leg 

 in flexion-position. 



13 Febr. 10 a.m. Both legs are hanging in stiffened tense- and abduction- 

 position with expanded webs. 



From these experiments, which I intend ro continue it appears 

 clearly, tliat the cutting of the appurtenant dorsal roots causes 

 retardation of the rigor mortis of the muscles.
