THEIR NATURE AND EFFECTS. 57 



1.88 P.M. Respiration still fainter. 

 2.6 P.M. Dead. 



Experiment VIII. 



A pariah pup of the same litter as the one in the last 

 experiment, and as nearly as possible of the same size, 

 had O'.'J cubic centimetre of fresh daboia-poison injected 

 into its shoulder subcutaneously. 



1.31 P.M. Injection. 



1.32 P.M. Seems in pain. 

 1.34 P.M. Defecating. 



1.3') P.M. Fell over in convulsions. 



1.37 P.M. Unable to stand. 



1.45 P.M. Lying down; is quite paralysed, but occa- 

 sionally groans. 



2. 1 P.M. Totally unconscious. 



2.16 p M. Eespiration failing. 



2.29 p M. Dead. 



In these two dogs, which were of the same age and 

 size, the daboia-poison was injected into exactly the 

 corresponding part in each, and subcutaneously ; but in 

 the latter experiment three times as much poison was 

 injected as in the former case. This was the only differ- 

 ence in the two experiments, and the result was that the 

 animal which had the larger quantity of daboia-poison 

 in four minutes had violent convulsions, and from that 

 time was quite paralysed, whilst the other only gradually 

 became paralysed, and had no symptoms of convulsions
