" In just the last issue of Science Today there had been an article on some new psychotropic agents of the group of so-called benignimizers (the N,N-dimethylpeptocryptomides), which induced states of undirected joy and beatitude. Yes, yes! I could practically see that article now. Hedonidil, Euphoril, Inebrium, Felicitine, Empathan, Ecstasine, Halcyonal and a whole spate of derivatives. Though by replacing an amino group with a hydroxyl, you obtained instead Furiol, Antagonil, Rabiditine, Sadistizine, Dementium, Flagellan, Juggernol and many other polyparanoidal stimulants of the group of so-called phrensobarbs (for these prompted the most vicious behavior, the lashing out at objects animate as well as inanimate—and especially powerful here were the cannibal-cannabinols and manicomimetics).
