THE ACTIONS OF PHYSOSTIGMA AND ATROPIA. 577 



Experiment 47-a. — A rabbit, weighing 3 lbs. 11£ oz., received 2 grains of 



extract of physostigma ; and, eight minutes and thirty 

 seconds afterwards, 5 grain of sulphate of atropia. Re- 

 covery took place. 

 47-b. — Four days afterwards, the same rabbit, now weighing 3 lbs. 

 8 oz., received 1*5 grain of extract of physostigma. Death 

 occurred in fifteen minutes and thirty seconds. 



Experiment 48-a. — A rabbit, weighing 2 lbs. 14 oz., received 15 grain of 

 extract of physostigma ; and, ten minutes and thirty 

 seconds afterwards, 5 grain of sulphate of atropia. Re- 

 covery took place. 

 48-b. — Twelve days afterwards, the same rabbit, now weighing 

 3 lbs. 1 oz., received 1'2 grain of extract of physostigma. 

 Death occurred in thirty minutes. 



Experiment 49-a. — A rabbit, weighing 3 lbs. 3 oz., received 1*5 grain of extract 

 of physostigma ; and, ten minutes and thirty seconds after- 

 wards, 0'5 grain of sulphate of atropia. Recovery took 

 place. 

 49-b. — Nine days afterwards, the same rabbit, now weighing 3 lbs. 

 5 oz., received 1*3 grain of extract of physostigma. Death 

 occurred in forty-six minutes and ten seconds. 



Experiment 50-a — A rabbit, weighing 3 lbs. 10 oz., received 018 grain of sul- 

 phate of physostigmia ; and, fifteen minutes and ten 

 seconds afterwards, 07 grain of sulphate of atropia. Re- 

 covery took place. 

 50-b. — Nine days afterwards, the same rabbit, now weighing 3 lbs. 

 10^ oz., received 0*18 grain of sulphate of physostigmia. 

 Death occurred in sixteen minutes. 



Experiment 51-a. — A rabbit, weighing 3 lbs. 8 oz., received 0*17 grain of sul- 

 phate of physostigmia ; and, twenty-nine minutes after- 

 wards, 5 grain of sulphate of atropia. Recovery took 

 place. 

 51-b. — Eight days afterwards, the same rabbit, now weighing 3 lbs. 

 5f oz., received 013 grain of sulphate of physostigmia, 

 Death occurred in twenty-four minutes. 



3. Several experiments have been described, in which the influence exerted 

 by atropia upon the lethal action of extract of physostigma and sulphate of 

 physostigmia was examined in clogs also. The following facts were stated 

 among the conditions and results of these experiments : —
