On opening it the lungs were slightly congested. Peristaltic move- 

 ments of intestine active. The blood from the heart was allowed to run 

 into a clean beaker. It was of a dark colour, but became red on expo- 

 sure to air. It shortly afterwards coagulated and formed a firm clot. 



Experiment VI. 



February 11. About 1 cubic centimetre of Daboia-poison (1 part poison 

 mixed with 4 parts of alcohol) was injected under the skin of the left 

 thigh of a guineapig at 1.13. 



1.17. Animal rubbing its mouth with its fore paws. It is restless and 

 moves about. There are slight twitchings, and it sits on its hind legs 

 like a cat. 



1.22. Very restless. 



1.27. Head is drawn towards legs in a twitching fashion. Animal 

 bites at the left leg. When it moves about, the left leg drags somewhat. 

 1.45. Has been very quiet and disinclined to move for some time. 



1.55. About 1 cubic centimetre more was injected into the right thigh. 



1.56. Both hind legs drag slightly. 



1.58. The animal is very unsteady and tottering on its legs. 



2.2. Both hind legs completely paralyzed, and, when the animal draws 

 itself forward with its fore paws, the hind legs trail out behind it. There 

 are twitchings of the fore part of the body. 



2.17. Hind legs and loins quite paralyzed. The posterior part of the 

 body lies flat on the ground, the abdomen being flattened out upon it. 

 Paralysis seems gradually extending to the fore limbs. There is general 

 twitching. It tries to crawl, but cannot drag itself forward, though it can 

 still move the fore legs. Gnaws the bottom of the box in which it lies. 



2.20. Almost motionless. Eye is still sensitive. Fluid has issued 

 from the mouth. The animal can still move its head. 



2.23. Convulsive movements. 



2.24. Cornea insensible. Weak twitches of the trunk still occasionally 

 occur; they seem to be of the nature of respiratory movements. Heart 

 beats strongly. 



In a minute or two afterwards the animal was opened. The heart was 

 irritable and contracted when touched. The ventricle did not contract 

 unless touched. The auricles were beating. The lungs were (I think) 

 slightly congested. Blood from the large trunks in the thorax was col- 

 lected in a vessel ; it was of a dark colour ; on exposure to air it became 

 bright red and formed a firm coagulum. Peristaltic movements of the 

 intestine were observed. 



Experiment VII. 



February Ilth. About | a cubic centimetre of milky-looking cobra- 

 poison was injected into the right thigh of a guineapig of moderate size 

 at 2-20. It became restless immediately, and the hind legs began to
