POISON OF SOME INDIAN VENOMOUS SNAKES. 83 



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 LVII. 



August 30th. — A cannula was placed in the trachea of a cat, 

 and 1^ decigramme of dried cobra-poison was weighed out and 

 dissolved in a small quantity (about 2 c.c.) 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. Kespiration 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 0*02 grain dissolved in a little water, as the 

 cat did not seem about to die. 



6.2. Injected IJ c.c. 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 paralysed. The respiration has a peculiar character, 

 the diaphragm seeming to relax with a jerk. The respiratory 

 movements are very deep. Peristaltic action of bowels. 



6.20. The fore legs are now becoming paralysed. 



6.25. Eespiration quick. Entirely diaphragmatic. Cornea 

 quite sensitive. The animal opens its mouth when the tail is 

 pinched, but not when the feet are pinched.
