Red Palmer, who was the kind of the developer of the capture gun, and he used nicotine alkaloids as his agent. That was the only one that was available then. Well, there were succinylcholine and curare were also used, but that was the only commercial one that was available. And so I knew that there was a very low therapeutic index, in other words, the effective dose and the lethal dose were very close together. So that was not a satisfactory agent. And then we started getting new ones that came on the scene, almost exponentially. The Etorphine or M99 was developed in England and was pioneered, its use was pioneered in Africa. I’m trying to remember the first time that I used this.
