Eabbit is still on the side, but usually- 

 quiet, except the shaking that is 

 caused by the incessant fibrillary 

 twitches. 

 Unsuccessful attempts are made to 



turn from the side. 

 The respirations are now quite free 

 from mucous sounds. The incessant 

 fibrillary contractions of the muscles 

 cause twitches not only of the skin, 

 but also of the toes, legs, ears, tail, 

 and even eyeballs. 

 After many efforts, the rabbit suc- 

 ceeded in turning from the side. 

 Some efforts were made to raise the 

 thorax on the anterior extremities, 

 but these efforts excited a series of 

 tremors, during which the rabbit 

 fell on the side. 

 The rabbit has now turned from the side. 

 A normal sitting posture was assumed 

 and maintained. There is, however, 

 a little drooping of the head. 

 The rabbit walked about with only a 



little difficulty. 

 Occasionally some moist sounds are 

 heard accompanying the respirations. 

 There is still a decided degree of 

 weakness present in the anterior 

 extremities. The fibrillary twitches 

 are still incessant in their occurrence. 

 The fibrillary twitches have diminished 

 in frequency, but not in the general- 

 ity of their occurrence, the eyeballs, 

 ears, feet, &c, being still sometimes 

 twitched. 

 The rabbit goes about without any 

 unsteadiness. For the first time 

 since the injection of atropia, some 

 fsecal pellets were now passed, which 

 are rather larger and slightly softer 

 than normal pellets. 

 The general condition of the rabbit 

 seems to be a perfectly normal one. 

 It is only with difficulty that some 

 rarely occurring fibrillary twitches 

 can be detected. A few more fcecal 

 pellets have been passed, but no 

 urine has been voided since the 

 commencement of the experiment. 



On the following day this rabbit seemed to be in an absolutely normal con. 

 dition. It fed largely, and went about actively and well. The pupils measured 

 ■^ths x ^§ths of an inch, and the rate per ten seconds of the cardiac contractions
