150 Analysis of the Airopa Belladonna. 



effects lasted about three quarters of an hour, and the dog 

 then resumed his former appearance. 



Second Experiment. At two o'clock I gave him two 

 grammes of extract with twelve of paste: the above sym- 

 ptoms re-appeared, but they were feebler and of shorter 

 duration. / 



Third Experiment. At three o'clock, I made him swal- 

 low four grammes of the same extract, with about 30 

 grammes of paste. 



A few minutes afterwards he was seized with a continual 

 but uncertain and difficult motion, chiefly in the abdominal 

 region : he uttered some plaintive moans. 



At half past three he experienced great difficulty in mov- 

 ing, and frequently fell on his hind feet : his respiration 

 was much obstructed. He endeavoured several times to 

 force his wav through the wall, which indicated a kind of 

 delirium : he was now seized with trembling in all his 

 muscles. 



At a quarter past four the animal lay down, and appeared 

 to be plunged in a profound sleep ; his pulsations were re- 

 peated faster than could be counted. 



At half past four be vomited the paste which he had 

 taken, some time after which he rose up; but he still walked 

 with difficulty, sometimes falling on one side, and some- 

 times on his crupper. He held his head very low, hi* 

 eyelids fell, and he did not distinguish objects; at least he 

 continually ran against the walls, and the furniture of the 

 laboratory: his nose was no longer affected by the smell 

 of ammonia, and his ears seemed also to have lost their 

 functions, for the loudest noise made no impression on 

 him. 



He had not lost his memory, however; for, upon placing 

 him in the same posture in which he was made to swallow 

 the paste, in order to give him some vinegar and water, he 

 became furious, as if all his powers were suddenlv renewed. 

 From this moment, the symptoms which he had exhibited 

 insensibly diminished, and about eight o'clock in the even-* 

 ing he recovered all his senses; but he was still much fa- 

 tigued. Next day he ate as usual. 



Every one must recognise in the above symptoms the 

 effects of narcotics, and drunkenness carried to the highest 

 pitch, from which resulted a kind of delirium. It is pro- 

 bable that if the animal had not vomited the greater part of 

 the matter before it produced its effects, it would have died.
