Vaseline petroleum which I have named Vaseline..." The name "vaseline" is said by the manufacturer to be derived from German "Wasser" "water" + Greek έλαιον ("elaion") "olive oil". In 1859, Chesebrough went to the oil fields in Titusville, Pennsylvania, and learned of a residue called "rod wax" that had to be periodically removed from oil rig pumps. The oil workers had been using the substance to heal cuts and burns. Chesebrough took samples of the rod wax back to Brooklyn, extracted the usable petroleum jelly, and began manufacturing the medicinal product he called Vaseline. Vaseline was made by the Chesebrough Manufacturing
Jelly-falls of Norway on natural jelly-falls also revealed caridean shrimp feeding on jelly carcasses. Finally, decomposition is aided by the microbial community. In a case study on the Black Sea, the number of bacteria increased in the presence of jelly-falls, and the bacteria were shown to preferentially use nitrogen released from decaying jelly carcasses while mostly leaving carbon. In addition, with the exclusion of scavengers, jelly-falls develop a white layer of bacteria over the decaying carcasses and emit a black residue over the surrounding area, which is from sulfide. This high level of microbial activity requires a lot of oxygen, which
