...mysterious killer as a medical student at Stanford. For two years he continued his research at the Rockefeller Institute, went on to the University of California. He discovered a phage of staphylococci (pus germs), showed that its inactivation by heat followed the same course as that of a protein. Poisons such as potassium cyanide and bichloride of mercury inactivated but did not kill it-in other words, like protein, it regained activity after the poison was removed. Finally Rockefeller Institute's John Howard Northrop isolated a phage, showed it to be a protein with the catalyzing properties...
...causes of these outbreaks are varied. Protein decomposition is probably the commonest cause. Meat and meat products of all kinds, fish, shellfish, milk, and milk products, such as cream, ice cream, cheese and all substances made with milk, such as pastry and pie fillings, may be the cause of the disturbance...
Cider has been a prominent source of acute upsets, due to arsenic residues. Arsenic produces almost exactly the same symptoms as decomposed protein...
...virus, found to contain carbon, hydrogen, nitrogen and oxygen like thousands of organic compounds, could now be contemplated as a huge protein molecule -a "macro-molecule." Was it alive or not alive? No known living thing is crystalline in form. It would be fantastic to imagine a crystalline pig. Yet the virus showed the ability to reproduce itself in great quantities when stimulated by contact with a plant. Thus the Princeton chemist had discovered an apparent bridge between living and nonliving matter. This was a discovery of Nobel Prize calibre...
...examination of the spinal fluid showed a normal cell count and protein content as well as a negative Wassermann reaction. The diagnosis of Disseminated Sclerosis of the Spinal Cord was made and concurred in by two eminent London neurologists. Unfortunately a post mortem examination was not permitted...
