128 WANDERINGS IN SOUTH AMERICA. 



when he tried the poison on a horse in the town of 

 Stabroelf, the capital of Demerara; the horse never be- 

 trayed the least symptom of being affected by it. 



Wishful to obtain the best information concerning this 

 poison, and as repeated inquiries, in lieu of dissipating the 

 surrounding shade, did but tend more and more to darken 

 the little light that existed, I determined to penetrate

 animals, the ensuing experiments. The larger animals 

 were destroyed in order to have proof positive of the 

 strength of a poison which hath hitherto been doubted:
