Oiilv siicli IVugs as coiild still Icup well uflcr llic u[)eraliuii, and 

 ill wliich fmm tlic lej:^ a( llic operated side no reflexes could be 

 excited, wliilst it could be done at the oilier side, and that sliovved 

 the so-called "llebepliaenonicnon" of Hkking were used for my 

 experiments. 1 add here a few j)rolocols : 



la. 6 February. liana esculenta, ol' which posterioi- root 8, Ï), and 10 of the 

 left side are cut. The frog continues leaping after the operation and makes 

 good use of the two hind-legs. The left hind-leg shows after the leap a new 

 elevation of the foot as Hering has observed. Reflexes at the left hind-leg 

 have ceased, a crossed reflex-movement through strong irritation of the right 

 hind-foot is observed. The reflexes at the right side are lively. 



7 February 9.30. The frog which is in a very good condition is hung at 

 30° Cels. in the damp case after the heart has been Ijound up. 



12.30. The right hind-leg shows increased dorsal flexion in tiie foot-joint. 



1.30. The dorsal flexion of the right leg has increased; when lifting the 

 hind-legs a stronger resistance on the right side than on the left one, likewise 

 in the knee and the hip. Left hind-leg still supple. Both fore-legs arc likewise 

 still supple. 



2.30. Still the same situation as 1.30. 



3.30. In right hind-leg still more resistance, left hind-leg still quite supple. 



4 p.m. Right hind-leg is in stiffened tense and abduction position with 

 expanded webs, foot-joint still supple. 



5.30. The right hind-leg is quite stiffened in knee and hip, in the foot- 

 joint partial rigor mortis. The left hind-leg is supple in all joints. On both 

 sides there is rigor mortis in shoulder and elbow. 



8 February 10 a.m. The frog has been hanging from 5.30 last night in 

 the damp case at 15° Gels. 



The right foot is now likewise stilfened, so that the right hind-leg stands 

 in entire tense and abduction position with expandeil webs. The left hip is 

 entirely stilfened, left knee and foot-joint are still n:ovable. 



9 February 10 a.m. The left leg is now also stilfened, only the knee 

 is still somewhat, but very little, less stiff than the right one. 



\\a. 10 February. Little Rana esculenta, of which on the Üth of Febr. |)osterior 

 roots 8, 9, and 10 have been cut, on the leftside. Mobility and reflexes 

 as with the former frog. 



10 a.m. The heart is bound up. The animal is placed in the damp case 

 at o0° Gels, for the experiment. 



1.30 p.m. The dorsal flexion of tiie right loot has increased, likewise the 

 hip flexion on the right side. Right hip begins to be stilfened, left hind-leg 

 is still quite supple. 



2 p.m. On the right side increase of the phenomena, on the left side still supple. 



2.30. Right hind-leg almost (juile stiff in still slightly flexed position, left 

 hind-leg still supple. 



3,30. Right hind-leg in stiffened tense and abduction position, the left 

 one is stiff in the hip ; knee- and fool-joint of the left leg still supple. 



4.-50. Both hind-legs are hanging in stittened tense- and abduclionposition 

 with exDauded webs. ,
