1874.] Poison of Indian Venomous Snakes. 113 



2.2. Heart acts as vigorously as ever. Artificial respiration was tried. 



2-15. Artificial respiration has been kept up, but has been of no service. 

 The irritability of the cord is much diminished, though not quite extinct. 

 The strongest current causes a barely perceptible motion. The heart is 

 still acting. There are spots of ecchymosis all over the intestines. 



2.40. The irritability of the cord is quite gone. The heart is still 

 acting. The blood collected from the large vessels coagulated firmly. 



Experiment LYII. 



August 30th. A cannula was placed in the trachea of a cat, and 1| de- 

 cigramme of dried cobra-poison was weighed out and dissolved in a small 

 quantity (about 2 cub. centims.) of distilled water. The solution was 

 clear and glairy, hanging in threads from the stirring-rod. 



2.40. Injected about two thirds of this solution under the skin of the 

 right hip. 



2.50. Respiration is quicker. The cat lies down and does not like to 

 rise. When raised it walks toward a dark corner, dragging the right 

 leg. 



2.58. Shivering of right leg and partially of body. No other symptom 

 than paralysis of right leg being noticed, a further injection was made. 



4.26. The remainder of the solution injected in the same place. This 

 also seemed to produce little effect. 



5.10. Injected *02 grain dissolved in a little water, as the cat did not 

 seem about to die. 



6.2. Injected 1^ cubic centimetre of a 2-per-cent. solution of cobra- 

 poison in distilled water, partly into a vein in the back of the left hind 

 leg, partly into the peritoneum. The left hind leg seems partially para- 

 lyzed. The respiration has a peculiar character, the diaphragm seeming 

 to relax with a jerk. The respiratory movements are very deep. Peri- 

 staltic action of bowels. 



6.20. The fore legs are now becoming paralyzed. 



6.25. Respiration quick. Entirely diaphragmatic. Cornea quite sensi- 

 tive. The animal opens its mouth when the tail is pinched, but not when 

 the feet are .pinched. 



6.37. Sensibility of the cornea seems nearly gone. When the inside 

 of the ear is tickled the animal shakes its head. 



6.43. Although respiratory movements still continued, artificial respi- 

 ration was begun. The animal was laid in an apparatus which kept it 

 warm. 



6.45. The cat tries in vain to vomit. The cornea is almost insensible. 



About 8.30 the heart-beats ceased. The body of the animal was ex- 

 amined next day at noon. Rigor mortis well marked. The body of the 

 animal had a strong odour of decomposition. The lungs were congested, 

 the right side of the heart gorged, the left empty and firmly contracted. 

 The pericardium contained a quantity of dark-red serum. A considerable
