Example text

These tiny red globules, whose job it is to keep my tissues supplied with oxygen, contain no chromosomes and play no further part in the search for my own Y-chromosome. Among the red cells, outnumbered by a thousand to one, float my white blood cells. Their job is to protect me from infection; to recognize a virus or a bacterium as foreign, an unwelcome intruder that must be eliminated. Once the white blood cells have identified their target, they draw on a fearsome army of weapons to destroy it.

THE ORIGINAL MR SYKES epidemics of diminishing ferocity over the next hundred years. The initial epidemic killed between one third and one half of the population in the space of eighteen months. It is hard to imagine the terrible effects of an epidemic on that scale among our ancestors. No family escaped as fear and death swept across the land like a swift black shadow. After the epidemic burned itself out, unable to find sufficient susceptible victims still living to sustain it, the survivors found themselves in a new economic landscape.

That is the reason why the salt solution has to be formulated so precisely. If it were only slightly more dilute, the white cells would be forced to swell even further and they too would burst. If it were just a little more concentrated, the red cells would be able to withstand the swelling pressure. 19 grams of salt per litre, no more and no less, do the red cells burst open and the white cells remain intact for us to collect. Once more the tube is carefully placed in the centrifuge and spun round and round.
