John Jacob Abel to successfully isolate the neutral base of epinephrine by adding ammonium to highly concentrated extract, a method Abel himself tried but failed due to the use of low concentration of extract. After Takamine's success, Abel himself remarked, with great candor, "The efforts of years on my part in this once mysterious field of suprarenal, medullary biochemistry, marred by blunders as they were, eventuated, then, in the isolation of the hormone not in the form of the free base but in that of its monobenzoyl derivative." Together with L.G. Rowntree and B.B. Turner, Abel devised what they called a "vividiffusion" apparatus,
Abel (hominid) fossil, and as such to the "Australopithecus afarensis". Abel (hominid) Abel (KT-12/H1) is the name given to the only specimen ever discovered of "Australopithecus bahrelghazali". Abel was found in January 1995 in Chad in the Kanem Region by the paleontologist Michel Brunet, who named the fossil "Abel" in memory of his close friend Abel Brillanceau, who had died of malaria in 1989. Of Abel remains only part of a jaw, which explains the little information descernable concerning its way of life. The few teeth confirm it to be of the genus "Australopithecus": it has a second premolar with a broad
