At laft he took two Drachms of Opium, which caft 
him into..a,jdeep,{kep .5. hue after. Vomiting- and voiding 
fetid Excrements, he recover’d by degrees his former 
brisknefs. So many, and thofe.fo notorious Poifons, 
could not -kill this Dog. • 
Some Weeks after, when the fame Dog had recover’d 
his former Vigour, we- try ’d on him the force of a much
