1 applied r 20 drops of the folution of 

 cpiiim on lint to the fkin of the hind 

 legs, for the fpaccs of half an hour to one 

 frog, an. hour to another, and an hour 

 and a half to a third. I then removed 

 the opium, and applied line wet with 30 

 drops oi fpiritus cornu cervi't and always 

 obferved that the animal, as foon as the 

 fpirit touched its ikin, exprelTed figns of 

 very confiderable pain j and that the parts 

 were inflamed, and the ilvin afterwards 

 mortified, in nearly the fame manner as 

 where the opium had not been previouHy 

 applied. Further, as the previous appli- 

 cation of the opium did not prevent the 

 fpirit a(5ling in the ufual manner ; fo the 

 fpirit was fo far from preventing the con- 

 vulfions and deadly fymptoms produced 

 by the opium, that it fcemed rather t© 

 accelerate them.
